This is our new “toy”, Dozuki or Japanese saw, that will be useful during next times to cut the tenons – connectors.
In order to understand the tool accuracy , we must understand its philosophy. Bruno Mari in his book “Da cosa nasce cosa” (1981) talked us about the strong relationship between the form of the objects and its use or function, and he supported his explanation by using, among others, Dozuki as an example.
Dozuki is a wooden saw, that as other Japanese traditional tools is different from western tools in relation with the cut direction. While western saws cut by push action, Japanese one cut by pull (the opposite). This fact, also means a change in the carpenter position during cutting, it is not necessary push with the body in the cut direction as western carpenters do. In this case we use gravity in our benefit so we maintain the handle in the button part and the blame up.
This use is safer (overall in case of break) so the blade can be extremely thin and we obtain accuracy and clean cuts.
As a result, the cutting edge penetrates extremely aggressively into the wood without generating repellency. Dozukis adapt their precision according to the thickness of the blade and are the protagonists of the great wealth of joints in traditional Japanese carpentry and can be used for cutting conifers or hardwoods.
In the picture you can see the quality of the finish and the appearance of our Dozuki, a beautiful object in itself because it is the result of a philosophy consistent with its use.
