Logmatic System – intelligent innovation

The Logmatic - Wedge Axe is a highly efficient, durable, ergonomically designed tool for splitting firewood and kindling. Safer and more efficient than an axe, easier to use than any comparable product on the market, the Logmatic is the perfect tool to have around for splitting wood for your stove or open fire.

The Logmatic - Wedge Axe is a truly revolutionary design improvement on the traditional axe, which has changed very little in thousands of years, and created specifically for splitting firewood. Since traditional tools used for splitting wood – such as a common axe or maul and wedge – require a great degree of strength and skill to use properly, it is not always safe for the average Joe to split wood with an axe. However because the Logmatic Wedge Axe is much more simple to use, the wood being split quickly and accurately with consecutive strikes in the chosen position, it is also safer.

The ergonomic design of the Logmatic – Wedge Axe means that there is no need to lift or swing this tool through the air or overhead, often causing injury, and no need to continually bend at the waist, which can cause considerable back strain.

1. Select the striking point with care by placing the wedge axe’s wedge-shaped point precisely where you want to split the block of wood. Begin splitting the block of wood from the edges – it’s easier that way.

2. Lift the striking bar up. It slides up and down inside the tube extending upwards from the wedge-shaped point and the wedge blade remains constantly in place.

3. Strike the striking bar down and it will cause the wedge point to embed itself in the wood. You can strike softly or hard – just as you like – and use repeated blows as necessary.

4. Each repeated blow targets on the same crack in the wood – not a single blow misses the mark. You do not disengage the wedge-shaped blade even if making repeated blows.

5. Also, each repeated blow directs the action of force towards the ground, this makes the Wedge-Axe very safe to use.

6. Thanks to this accuracy of the splitting action, you can benefit from existing cracks in the wood and also go around knotty parts.

7. From a working point of view your posture remains straight and this means that their is a massive reducion in strain on your back.

8. The block of wood will split readily thanks to the weight of the striking bar, which is simply obaying the Law of Continuity, and muscle power.

9. When using the Logmatic - Log Splitting Basket (LM-1000) the split firewood is formed into suitable bundles for carrying and for drying quickly.

The Logmatic – Wedge Axe (LM-250) is a truly revolutionary and innovative alternative to conventional firewood splitting. It perfectly combines the simple and practical technology of a a traditional splitting forged wedge with a hefty striking bar to simply and easily split even the biggest log, into firewood and kindling.

As far as truly great systems go the Logmatic - Wedge Axe splits wood safely and ergonomically . Splitting takes considerably less time than with an axe.

To make the Logmatic – Wedge Axe even more efficient it is advised that a Logmatic Splitting Basket (LM-1000) be used, which will securely support several logs all at once. By supporting several logs, all at the same time, the basket allows you to concentrate on the splitting and not have to worry about supporting each log as it is being split. Also, as each log is split it continues to support the logs that are yet to be split. Once all of the logs have been split the Logmatic – Log Splitting Basket then functions as a smart log carrier, and basket or rack, at your fireside.

Splitting firewood and kindling has never been so simple and safe, efficient and ergonomic!

The Logmatic – Log Splitting Baskets is both durable and modern in design, and forms part of Logmatic log splitting system. The Splitting Basket keeps the wood to be split in an upright position during the splitting process, which makes the job of splitting logs much easier and very much safer. The Splitting Basket also serves the purpose of the traditional firewood basket when carrying the split wood into the house or the woodshed and keeping it in a tidy formation next to the fireplace.

The Logmatic - Base Plate

The Logmatic – Log Splitting Basket’s base plate made of formwork thick heavy duty plywood, which will support the logs to be split in the basket and allow maximum force to be applied to each log as it is being split. However, the Splitting Base is at its best when used on a non-giving surface such as concrete or paving slabs.

The idea is to connect the Splitting Base to the Splitting Basket when splitting firewood and then to disconnect it when the wood has been split, and the pieces are ready to be carried into the house or the woodshed. This product can also be used as a base without the Splitting Basket when splitting firewood, but is at its best when used together with the Splitting Basket.

Quality product, ergonomic and safe to use.

Decades of design and experience in the field of wood harvesting and forestry machinery back up Logmatic products. Logmatic products received international acclaim at a forestry trade fair held in France, where the Logmatic won the Award of Security. However, the best accolade is from the tens of thousands of users, who are making this safe and efficient product known in all the major countries of the World. Nordic quality and guarantee stand behind Logmatic products.

The wedge axe is safe to use because the direction of the action is towards the ground. Thanks to this accuracy of the splitting action, you can benefit from existing cracks in the wood and also go around knotty parts. The block of wood splits readily thanks to the weight of the striking bar, the Law of Continuity, and muscle power. The split firewood is gathered into suitable bundles for carrying and drying quickly.

Environmentally Friendly

The environmental and efficient burning of wood requires the wood to be below 20% moisture content. Many people don’t understand the extent to which the environment is polluted by burning wood that is too wet, which besides releasing pollutants can deposit tar in the chimney. According to the producers of the Ekoisti television program in Finland, one-third of the methane released, which is 20 times worse than carbon dioxide, is a result of the burning of wood that is too wet.

Wood can be dried in a woodshed or shelter or if not available stacked in rows on pallets or paving stones with a narrow tarpaulin over the top to keep out rain or snow. This allows a good circulation of air, which will dry the wood. To burn, the wood should be dry and then taken into the house a couple of days before burning to become ‘house dry’.

For use in wood burning stoves wood should be split into pieces about 5-10 cm thick. This is easily achieved by using the Logmatic Wedge-Axe and Splitting Basket to produce the right size firewood quickly and then easily carry the wood to where it is needed. Pieces about 5-10 cm thick produce a good burn in woodburning stoves and the rate of burn is controlled by the vent, i.e. how much the stove is damped down and not by the thickness of the wood.

Application and Operating Principles

The LOGMATIC wedge axe is designed for splitting blocks of wood placed at the user’s feet. Its efficiency is based on repeated blows, which (due to the structure of the wedge axe) are always directed at the same spot. It is not necessary to force the wood to split with one powerful blow, but instead to split the wood in a controlled and energy-conserving way with several light blows, the force of the blows depending on the strength of the person using this tool.

As with all new, repeated motions, the beginner should restrict the first work session to between half an hour and an hour, depending on the work conditions and work pace.

If you happen to be suffering from an illness restricting normal body motions, please consult your physician before starting to use the wedge axe.

The LOGMATIC wedge axe is designed to withstand impact stresses directed against its blade. Do not try to dislodge a jammed blade by bending or pulling it up towards the stopper. Likewise, do not try to split materials harder than wood.

Although the LOGMATIC wedge axe is safer to use than conventional axes, it should be remembered that it is a sharp-bladed tool and should be handled as such. Pay special attention to the words of caution given below, and do not allow persons unfamiliar with the wedge axe to use it.

Beginning To Use Your Wedge Axe

1. Hold the wedge axe by the lower grip on the guiding tube and raise it upright while avoiding the blade. Get used to always carrying the wedge axe by this grip.

2. When using wedge axe type, place the LOGMATIC wedge axe firmly on a horizontal surface and remove the knurl-headed screw holding the blade protector in place. Note that this screw, when removed, releases the locking system holding the striking bar and guiding tube together during transportation and storage.

Using The Wedge Axe

Wear proper protective clothing. Use thick safety gloves and proper footwear!

A firm, horizontal surface (e.g. a plate-like piece of concrete) is required for efficient splitting. If the purpose-built LOGMATIC splitting plate is not available, a large tree stump, a piece of thick plywood, particleboard, or a platform made of short planks resting on compact soil are equally suitable.

Place the block of wood to be split upright on the splitting plate and position the blade of the wedge axe on the block. You will note that you can select the desired splitting point with precision and thereby benefit from any natural cracks in the wood. Continue to hold the wedge axe by the lower grip with one hand and then snap the striking bar up and down with the other hand so that the blade of the wedge axe sinks into the wood and stays there. Next, grab the wedge axe by both of the grips and lift the striking bar up. Try to keep the striking bar at right angles to the top of the block of wood and bring the striking bar down. Repeat this until you have split the block of wood.

When splitting large blocks of wood, do not start from the centre of the block. Instead, start splitting from the perimeter of the block. Splitting is easier this way and you don’t have to handle the same block several times.

Usually, the butt end of the knot does not come off the stem wood parallel to the knot. Split the block of wood first from other directions and, if necessary, place the knotty piece flat on the splitting plate and place the axe blade very close to the upper and lower side of the knot parallel to the wood so that the knot will split off.

You can also place long pieces of pre-split block of wood flat on the splitting plate and split them into smaller pieces with further blows to the side.

When splitting small blocks of wood, with diameter less than 12 inches, the job becomes easier if you bunch such blocks together using the purpose-made LOGMATIC splitting basket. If such a basket is not available, you can bunch the blocks of wood together by means of a hoop made of a discarded car tyre.

Stack the wood to be split loosely within the splitting frame so that there is sufficient room for the wood to be split. You will soon find that you can split the blocks of wood easily one-by-one, and thereby avoid unnecessary bending to pick up pieces of wood.

Developing Technique

As soon as you master the basic technique, you can use more power with one hand and notice that such force is enough to split blocks of wood. We recommend that you place large blocks of wood in the splitting basket or frame before splitting them so that they will remain upright and support one another.

Further splitting and making of kindling wood can then be carried out in a controlled manner.

Remember that you must not “push” the blade into the wood at the end of a blow. Instead, the blade’s penetration is based on the velocity of the striking bar. At the end of each blow, you should slightly loosen your hold on the grips and allow the striking bar to do its job.

Finishing The Job

When you have stopped splitting wood, place the wedge axe in a horizontal position and reattach the blade protector. If left unprotected, the blade may inflict serious injury.

Before tightening the knurl-headed screw, make sure that the striking bar is inserted completely as otherwise the guiding tube will not lock properly.

Store the wedge axe in a horizontal position or hang it by the blade protector hook in a safe place and when transporting the wedge axe in a car, place it in the boot of the car and secure it firmly in place.

The Logmatic System

As a user of the LOGMATIC system, you have the most to gain, including safety, efficiency and ergonomics, from the wedge axe by also using the purpose-made splitting plate and splitting basket.

When the splitting basket is placed on the splitting plate, it is automatically propped up in the proper position. There is a handle attached to the plate by means of which the plate and the basket (together with the split wood) can be lifted upright with the user using one hand to support the system. When placed upright, the splitting basket forms a wood-carrying basket with handles and supporting legs. The wood in the basket can then be moved to the wood pile or carried to the fireplace.

Note that the splitting basket (must not be placed closer than 3 ft to a fire to avoid overheating.) When using the LOGMATIC system, there is no need to handle the same pieces of wood more than once nor to carry them in your arms after splitting. All stages of work are performed rationally with minimum of stress and, most important of all, with improved safety.

Should you find any defects in this manual or in the LOGMATIC system, please send in your comments and suggestions. We shall be grateful for all comments as our aim is to constantly improve this product.

WORDS OF CAUTION

1. When handling the wedge axe, always hold it vertically by the lower grip.

2. Do not change your hold to the upper grip as then the guiding tube and the blade will fall off.

3. When striking the striking bar down, make sure that you hold the device by the rubber grips.

4. If you intend to split a thin piece from a tough block of wood and you notice that the piece does not break off but instead starts to bend and yield, stop trying to split the block. Otherwise there is the risk of the wedge axe’s head jumping out of the cleft in the wood and off the block altogether.

5. Always maintain a steady position with respect to your legs, keeping them slightly apart and at a safe distance from the block off wood being split, especially if you are not using the protective splitting basket.

6.Always aim your strikes to the part of the block of wood furthest away from you.

FAQ

1. The traditional axe has been with us for thousands of years, is it time to try and shake its position or is this even desired?

The traditional axe is here to stay. Experience and knowledge of axes goes back thousands of years. However, development requires further specialization so a new method for manual splitting and handling of firewood is now available.

2. What kind of new qualities does this invention provide?

Among others, more efficient usage and improved safety: the strike line of the axe and the sledgehammer is a curved line running from top to bottom towards the ankles. With a wedge axe this line is always perpendicular from top to bottom towards the Logmatic splitting plate. With the Logmatic splitting basket it is possible to chop one bigger log or several smaller logs at once. Logs are no longer lifted on top of the chopping log as is done when splitting wood with a traditional axe, and logs do not “fly around” either. The logs are ready to be carried to a sauna or shed immediaPhny after splitting.

3. Are there any other differences? Why is the term “precision tool” used in this context?

When working with a traditional axe the desired target is always chosen before the strike. The result, however, depends entirely on the skill of the person. With a wedge axe the blade is always set precisely on the spot where the log is easiest to split; therefore, less strength and more in Phnligence is required in splitting wood. In addition, every consecutive strike with the wedge axe continues the work by hitting the same spot until the log is split in two.

4. Is it possible to use car tyres as a kind of splitting cylinder?

Of course, especially if you wish to save money and the number of logs are limited. However, carrying logs to another location is a different problem. Carrying and piling logs is complicated because they are placed in a pile one by one if the firewood basket is not used, and carrying logs with a tyre is impossible.

5. Is the wedge axe environmentally friendly?

Efficient drying and the environmental burning of wood requires that the firewood be chopped into logs of 5 to 10cm in width. The recommended drying time for firewood is one year. With the Logmatic wedge axe and basket this – as well as splitting kindling and ‘eco logs’ – is quick and efficient. The basket makes carrying the logs to the place where they are split and stored easy.

6. What does the Logmatic System really mean?

The Logmatic system, i.e. the wedge axe, and the basket and plate, is based on a new kind of thinking that ‘revolutionizes’ all phases of splitting and handling firewood:

  1. Logs are easy to carry to the desired location in the basket either by hand or with a small wheelbarrow.
  2. Splitting is carried out within the basket as a kind of mass production – not one by one.
  3. Note! Lifting the logs and picking them up afterwards is history – this is no longer required.
  4. After splitting, the logs are taken to the fireplace or a shed to be dried in the basket.
  5. In addition, the high-quality basket is an excellent place to store the logs indoors.

Attentive readers have probably already noticed that the sound of a splitting log is yet another phase in the logistic journey of firewood from woods to hearth.

7. Safety?

According to study No. 293 by VTT, the estimated number of accidents involving axes that required medical attention was over 4,200 in Finland. The most frequently injured parts of the body were respectively legs, hands and eyes (up to two or three percent of all injuries). When splitting logs with the Logmatic these hazards are minimized provided that the instructions are followed.

8. Can women the young, the old and people with back problems use the Logmatic?

The ‘macho image’ of splitting logs is history! Neither great strength nor skill is required, nor as the Logmatic wedge axe is used in an upright position does the user have to bend and so there is little strain to the back.

9. The wedge axe – a cross between a splitting wedge and a sledgehammer?

This is true in a way. However, a guide tube has been welded onto the wedge axe head. Unlike a sledgehammer, the striking bar is lifted up to one meter and brought down. In this way, each strike of the ‘hammer’ is aimed safely at the ‘wedge’, and the log is split as result of the weight of the striking bar, muscle power and repeated strikes.

10 How did it all begin?

A tall birch once grew in the garden of Sarvela. This birch did not die of old age, but was blown down in an autumn storm. Jussi Sarvela took an axe in his hand, for the first time in years, and after having spent half a day trying to clear the great tree away, he became convinced that there must be an easier way to do this. Mindful that man’s idleness is the greatest motivator of creativity Jussi devised a better solution.

Safety

Forexpo 2000 Safety Award Winner

EUROPEAN RECOGNITION, OSCAR SECURITE 2000 PRIZE TO A leading Central-European special exhibition FOREXPO, dedicated to the development of forest- and wood-related technology, awarded System Logmatic a new Finnish product and method, the esteemed Encouragement Prize in the face of some tough competition . The jury’s decision was influenced, first and foremost, by the overall safety features of System Logmatic as well as its general properties.

The accomplishing of improved safety when making household firewood has been found to be a central problem in studies conducted in this area. For example, VTT Finnish Technical Research Centre states in its research results (no. 293 ), that more than 94% of the accidents involving the use of an axe took place in normal use and less than 4% of these accidents were caused by incorrect use. Thus, the study reports, approximately 4,000 Finns per year are injured to such an extent that they need to seek medical attention despite the fact that they had used an axe in the normal way.

This figure applies solely to Finland, with a population of 5 million people, which corresponds to less than 1,000th of the world population. Consequently, one can only guess at how many people injure themselves the world over in connection with firewood splitting. It would appear then that Logmatic Wedge-Axes could do away with a lot of global pain.
