This YouTube video about Japanese Saw Vise for Sharpening Japanese Hand Saws (kataba, ryoba, dozuki)

1. Why when sharpening Japanese saws need vise / vise? can he be sharpened barbaric (stepped on foot for example (without vise / vise saw)?
2. What is the difference between western saw vise and japanese saw vise? Can western saw vise be used to sharpen Japanese saws?
3. What about the difference in the file used between western saw and japanese saw?
4. etc. only.

Answer:
1. Due to Japanese saws made very thin (especially dozuki whose thickness is only 0.35mm compared to carl schlieper hand saws which have a thickness of 0.9mm) then when sharpening it is prone to vibrations or back-pounding, this vibration or back-pounding will result in two possibilities: the saw is broken or the file is broken, in other words, sharpening the Japanese saw must use vise / vise / vise and cannot or rather be difficult to sharpen barbarically (stepped on foot).
2. Japanese saw blade requires a little tilt (tilt) while in western saw vise it can be upright or tilted (the term sloped gullets), Japanese saw vise must be easily rotated to and fro to find the right position of thought while in the western made fix.
3. The file used to sharpen a Japanese saw is different from an ordinary manual saw file, a Japanese saw file has an angle of 15-20 degrees, while an ordinary manual file saw is an equilateral triangle having an angle of 60 degrees each.

miser saws are coated with diamond (diamond coated) some are in the form of ordinary hard steel. Diamond coated Japanese saw files can be used to sharpen Japanese saws that go through the process of heat treatment at the edges (edge โ€‹โ€‹hardening) or non-hardening Japanese saws but if diamond coated files are used on non-hardening Japanese saws it is less strong (less durable) easily eroded. While the miser is not coated with diamond only for Japanese saws that do not go through the heat treatment process.

That's all for the ins and outs of sharpening Japanese saws (ryoba, kataba, dozuki) in detail, maybe uploaded in subsequent videos (if there is free time ...), see you later and hopefully useful ๐Ÿ™‚ Woodworking video.
