Japanese chef knife DIY project by DOROCO.
HSS or HS (high-speed tool steel) is an excellent material for sushi knife DIY.
Designed to withstand harsh operating environment and high heat (as with the drill bits or machine saws), HSS makes a very sharp and durable knife.
Making a knife using an HSS saw blade, NO HEAT TREATING is required because the saw blade comes already heat treated to HRC 62-64 from the factory, and the material stands the heat during the cutting and the grinding (it does not get soft or change it's properties). The only downside... it's hard and tough to cut and grind.
The M2 steel, which is familiar to knife hobbyists, belongs to this category.
This Channel will be updated weekly, with different videos on making Japanese chef knives and using them : ) Please leave a LIKE and SUBSCRIBE if you enjoyed my video.
Thank you for watching! - DOROCO -

Nice work👍🏼 what basic materials I can use for Handle of the knife?

@diydoroco-japanesechefknif7866 4 жыл бұрын

Thank you for your interest : ) Traditional handle materials for Japanese kitchen knives would be horn for the cap and magnolia for the handle, but they are not fancy... I prefer hard wood such as ebony for the cap and combination of hardwood and softwood for the handle. Hard wood with different colors and soft wood with beautiful grains may be used basically, and a waterproof finish using natural oil or resin is required to keep it dry at all times. Popular wood such as walnut, padauk, ash, olive can all make nice handles. Beware though when using hardwoods such as ebony, rosewood, wenge, cocobolo, bocote, etc. The sawdust and sand powder can cause an allergic reaction! So, be sure to wear a mask, and keep your garage well ventilated : ) Hope this helps. Cheers!

@kalleklp7291 4 жыл бұрын

Excellent job..! I like the classic look of it with just one bevel. I bet you've already sharpened to a razor grade sharpness? I made a few knives from sawblades myself and also used old files for the purpose. The trick is not to let it get so hot it changes color. Then the hardness is ruined. That knife can serve you for years to come..

@Divine_Serpent_Geh 2 жыл бұрын

These saw blades are High Speed Steel (M2/M4 more than likely). They’re used for cutting metal and they derive their name from being able to retain their full hardness from the high temperatures generated by the friction of metal on metal cutting. So there is no worry about getting the blue/purple colors here. Just have at it with a grinder like in this video, you pretty much have to anyway. There’s just no other way otherwise. Note: the alloying these steels have is what makes this possible. Molybdenum and Silicone IIRC. Where you want to avoid the colors is on something like circular or sawmill blades. Those are low alloy, carbon nickel steels for incredible durability, but will have their hardness reduced if you get them too hot. By the way, those are excellent steels as well, extremely tough and very strong (hard).

I did lots of file tests over the cut edges and ground blade to make sure the heat did not soften the steel. Cheers.

@diydoroco-japanesechefknif7866 3 жыл бұрын

I am sorry to hear that you had problems... HSS materials are often harder than the drill bits and you cannot make holes on them unless you soften the materials by annealing them. Wrap the blade with wet towel and heat the handle stock using a torch until the part to be drilled begins to glow. Then let it cool slowly in room tmeperature. Only then will you be able to drill the handle stock. Also, there is a simpler alternative; instead of drilling holes, cut out a rectangular hole in the middle of the handle stock with an angle grinder, and use like two pins to fix the handle cover at the left and right edges of the box. Hope this helps : )

Nope. Not as long as you ruin the original composition of the blade by overheating it during the cutting and grinding. HSS was designed to withstand quite a high temperature anyway. I'd say you are in the safe side unless the blade burns in red during the cutting and grinding. Hope this helps : )

@MountainFisher 3 жыл бұрын

First off HSS or high speed tool steel can be many different alloys, many configurations. Obviously the alloy you used didn't soften up from being cut with an angle grinder so I'm going to guess you got lucky and obtained some high quality M4 type hot work tungsten alloy. Typical for a Swedish made steel. Some of the blades made from Chinesium are barely more than very high carbon steel with some molybdenum added to add some toughness. Just as well buy a Nicholson file. Cutting some HSS with a grinder will soften the edge back a good 1mm and it must be ground back without creating heat. If you do not have means to heat treat a knife a HSS blade can be used, but avoid cheap one, but you'd be better served to get an old Nicholson file and pop into your oven and heat up to 425 for two hours and let slow cool then do it again. Then it will be around HRC60 and easier to grind than a fully hardened file. Keeping water handy and dipping often. Whatever you do don't overheat the blade.

Thank you for your comment. The material I used is almost identical to M2 as far as I know (DMO5 or SKH-51, a bit softer than M4 but a little tougher). I love your idea of softening a high quality file a bit for the job. I might give it a try! (Do you fly fish by the way? : )
