Japanese saws

why use japanese saws?

Japan boasts a millenary tradition in the field of wood. From the simple house to the temple (even the foundations) are built almost exclusively of wood. Many of these masterpieces often made only with hand saws and other traditional tools are now part of the cultural heritage of humanity. Over the centuries a great wealth of knowledge has developed which, combined with the profound experience in metalworking, has produced extraordinary tools for woodworking. Among these it is natural to think first of all of saws.

These saws were once made by hand in small workshops. Today there is a shift towards industrially produced saws with disposable blades, basically for three reasons:

  • For an inexperienced user it is difficult to sharpen these rather complex geometry saws.
  • ordinary files can't cope with these laser-treated teeth - they're harder than files.
  • the replacement blade is cheaper than the time it takes to sharpen

Japanese saws are becoming increasingly popular, especially in the professional field, simply because they are technically superior.

Japanese saws

Cut to shoot

European saw

Push saw

Japanese saws cut in the pulling phase, while European saws cut in the pushing phase. And it takes very little to change your habit!

Japanese saws

The pull keeps the blade straight

European saw

The thrust crooked the blade

A Japanese saw blade naturally stays straight when traction cuts, whereas a European saw always risks bending.

Pull machining allows you to use a thin blade

European saw

Push machining requires a thick blade

Since Japanese saws are pulled, the blade can be much thinner than European saws, which instead need to be thick to withstand the force of the push cut.

Thin cutting requires less effort

European saw

The large cut requires more effort

Also keep in mind that a thin blade requires less material removal, which means less time and effort to complete the job.

Quick and clean cuts

Slow and coarse cuts

The result: fast and clean cuts with the Japanese saw. Forget all previous experiences and beliefs about hand saws!

The three main types of saws are:

  • the Dozuki - a saw with teeth on one side, equipped with a back, which stiffens the blade allowing very precise cuts
  • the Ryoba - a blade with teeth on both sides for cuts both along and across the grain.
  • the Kataba - a saw with teeth on one side without a back. Normally used for cross grain cuts.

According to the type of teeth in Japan it is customary to distinguish between saws mainly intended for cutting along the grain or across the grain. The trapezoid toothing shown in the enlargement has the teeth alternately set and is particularly suitable for cross cuts. The triangle toothing, on the other hand, is reminiscent of that of European saws and is particularly suitable for long-grain cuts.

Which type should I take?

The answer depends on the type of use and the user's experience.

But we can provide some tips:

First of all: the instructions for use are not binding and therefore you can make cuts along the grain with a saw suitable for cross cuts and it works very well, it will take youjust a little more; just as you can with a saw for long cuts make transversal cuts, you will simply have a cut a little less clean. In any case, the saw does not get damaged.

If you are a beginner, don't buy the most expensive saw you can find. In my experience, blades are changed not because they are worn out, but because they are damaged by improper use. With a cheap saw, this is less displeasing.

A back saw is easier to use than one without. However, the cutting depth is limited and the blade is a little more delicate, precisely because it is thinner than a backless saw. On the other hand, a backless saw allows for deep cuts and moves better in confined spaces, making it a favorite of those who work in construction.

What should be your first purchase, evaluate it for yourself. In the long run it is advisable to have two models at home.

However, there is no one-size-fits-all solution. Do not hesitate to ask for advice, by telephone, fax or email. Better yet: go to the store and try it out. You will see that the choice will come by itself.

Regarding the dimensions: the width is measured in the center, the same for the number of teeth per inch or centimeter because this value for triangular-shaped teeth decreases as it approaches the handle.
