Fugaku Japanese Saws:
[ Ссылка ]
In this episode of Cool Tool Tuesday, Jesse gets excited about the two new Japanese saws in the store!
Fugaku Japanese Saws are the same as all other Razorsaws with the added benefit of having a blade that folds back in on the handle. This makes it handy for two reasons -
When not in use the hardened teeth are protected from damage. Impulse hardening, while improving the life of the teeth also makes them brittle and protecting the teeth from falls and knocks will extend the life of the saw.
The compact nature makes it easy to store both in your workshop where a full length Japanese Saw seems to take up a lot of space or can be put in a tool bag and pouch for easy use on a jobsite.
Available in both the Dozuki-style with spine (with a maxmimum depth of cut of 50mm) or Kataba that can work on all material thicknesses, the blades are both 240mm long an 17TPI for general crosscutting work. The Dozuki has a 0.3mm thick blade while the Kataba requires a thicker 0.6mm for improved rigidity while cutting.
Why Japanese Saws?
The most striking advantage of the pull stroke saw is the ability to cut accurately with less effort. There is less binding, buckling and breaking of the blade because the blade is under tension on the pull cutting stroke rather than under compression as in Western style saws. The ability of a saw to accurate cut along a line i.e. cutting control, is directly related to the saw's ease of cutting. Invariably, the saws that cut the most efficiently are the easiest to control.
Because Japanese saws cuts on the pull stroke, it permits the use of thinner, harder steel, and the blade can be much sharper. This will allow the blade's to have thinner kerfs, which reduces the effort of cutting because you are sawing a smaller amount of material compared to a Western-style saw, which means more smooth and accurate cuts.
Why Buy the Razorsaw Brand?
In 1969 the company marketing the RAZORSAW brand invented the system with the thinnest blade ever for the most efficient cutting. The introduction of this new disposable saw amazed the Japanese woodworking industry and its success has proved that this method of manufacturing Japanese saws has taken the world by storm.
RAZORSAW are continuously looking ahead. Development in the future will bring further benefits as they continue a history of combining human wisdom with technological innovation.
Each blade is impulse hardened. Impulse hardening is a new technique of heating for 1/1000 second by impulse energy at an extra high frequency resulting in hard and tenacious steel that gives remarkable durability. It is recommended you pull the saw towards you with a slight power keeping the edge at a 15-degree angle. Then push softly and repeat. Once you have used a RAZORSAW you will wonder how anything else in the workshop did the job.
