【With subtitles】How to Preparing new Japanese chisels for reliable service

I purchased a chisels for the first time I will prepare the chisels for reliable service Remove butt hoop Use small pieces of wood Use a metal file to loosen a gradient With this gradient it can be fixed firmly to the handle The angle of the gradient is very gentle. About 10 ° Hit the part to insert called "kigoroshi". In order to improve the suction of water, drop the varnish of the part of the handle. To knock down. Knock down until the edge of the handle is about 1 ~ 2 mm If you do not enter、 "kigoroshi" to redo Soak the handle in water Raise the head of the handle (part of the tree) so that it spreads outward It arranges the shape so that the handle becomes a dome shape We will chamfer not to cut our hands next to fleas. (Chamfer is on the hand side of the blade, half range) Absolutely do not chamfer the cutting edge Do not use metal file. Use grinding wheels and oil stone For details of the whetstone used, please refer to the description section of the video. This is a # 800 diamond whetstone The bottom is an aluminum plate The aluminum plate puts out a flat surface and pastes waterproof paper Waterproof paper is used for nonslip and face repair of grindstone This is a # 3000 diamond whetstone This is an 8000 whetstone For this simple sharpening machine, please refer to the past movie how to make your own Imprint "Ibota" on the corner (1 cm) of the grindstone. This is to clog the grinding stone and not to sharpen the blade until it is backed down Because it is a diamond whetstone just spray water with misting it is OK 【Uraoshi】 We grind the back of the chisel to the plane Since I am not a job, I work slowly and carefully. Working until it is flat while looking at the back side Sharpen while slightly shifting without using the same place It became a plane Then finish with #3000 → #8000. If the grindstone is prone to clogging, use "Nagura" It is flat, if it looks like a mirror OK Correct the surface of the whetstone Remove abrasive grains Sharpen the Blade edge We will make cutting edge with stable sideways grinding (moving the blade sideways) Use the whole whetstone to grind so as not to reduce one side I will advance the grinding so that the cutting edge becomes a flat surface, while looking at the blade return # 3000 with medium grinding Finish with # 8000 Make sure the cutting edge is flat. Do not become as arc as possible ... Finally a vertical grinding wheel (move the blade vertically) Place the abrasive stripe of the cutting edge vertically. Vertical grinding tends to round the surface, so sharpen it in one direction. I will return the blade for the first time here Take the burr of the cutting edge Polished up. Apply oil to finish
