    ~W I P~ First Stock Removal Knife Project

    Also, even though I have a nice 2x72, I still finish my profiles with files. I like slower, more precise. I begin with a large double cut bastard and I drawfile once the profile is done to smooth out and i'm ready to grind the bevels. And grinding profiles is pretty hard on belts, I also save money this way.

    Zircon belts are pretty good on soft steel. It would be a cheaper alternative for pre HT grinding. But nothing compares to ceramics on hardened steel.

    Ya, this also explains why Ni Mai white#1-2 billets are apparently non existent on the market while San Mai is easy to find. He told me Kata ha blade makers do their own Ni Mai billets.

    I am having a hard time trying to finish a pair of black walnut handles. Seems that no matter how many layers of oil I put on, those damned pores just won't fill up. How do I achieve a smooth finish on such porous wood? Should I sand the oil off and repeat? I was sanded to 600 and buffed to a very smooth finish but that darned wood seems full of hole.

    It was just to make sure there wasn't any dirt left before I put an oil coat on.

    Thanks Rich it seems handy, I'll look that up Tonight I decided to wet sand both handles with 1500grit until almost no pore were visible. Cleaned and dried with brake cleaner and reapplied oil. So far it seems it worked well. I'll update tomorrow

    Yeah, that's why I mentioned kitchen knives. 5160 may not be able to hold the accute edge required for these. I believe 1095 shines the most at high hardness, just like W2 and is ideal where higher hardness is required.

    Also, it's just a detail but I am unsure if 5160 is so good in the edge retention department, at least not with kitchen knives since it's working hardness is relatively low(cleaver being an exception).

    It's a matter of how comfortable you are to deal with warps, but you should go no thinner than 1/32". This steel decarbs if you soak it at critical temperature unless you use ATP-641 so you should keep some meat at edge to compensate. Since I've got my 2x72, I keep around 1/16" at edge before HT.

    I spoke with an apprentice bladesmith from where I live who went to learn in Japan and he told me Kata ha (chisel ground) blades are not that common there, it's a type from a particular region which I forgot the name and is used for specific blade types such as kiritsuke. Most of their kitchen knives are actually double beveled but usually partial flat ground. The guy married a Japanese so he's going to live there in the summer . Edit: according to Murray Carter, they actually put a secondary bevel(they call it the primary edge) but it's so tiny it's barely visible.

    It's not so complicated if you do it step by step and ask questions on the way. But you should do what you want or it won't be fun . Go ahead and see if you can replicate my mustard etch! Buy 80CrV2, I love that stuff.

    That would be cool! I do mostly hidden tangs lately, it's up to you if you want to send a block or scales.

    I honestly don't know if coffee can be used but I never heard of it. I think it's too mild and would not dig deep enough. Depending on the desired effect, you can use diluted ferric of warm lemon juice. The idea is to polish the blade as far as you are willing to go (1500# in my case). Then do very short dips in diluted ferric(I use 1:7) and very gently and slowly remove the oxides with 3000#. Edit: duh Alan was faster.

    A flat bevel that doesn't go all the way to the spine. Pretty common in Japanese cutlery.

    Because I live in Canada and it's hard to find someone to do it at a reasonable cost. Edit: it is also out of the question to equip myself for stabilizing because I could only do it in the shed and there's no room left. I think I'll just stick with denser woods or buy already stabilized.

    I made a nakiri with 3/32"X2" stock. I ground full flat and I believe it was a mistake because the edge was overly thin. I believe a partial flat would have been ideal for edge geometry and food release. Edit: try this calculator and put a 3.5° bevel angle to see. On 3/32" stock the bevel should be no wider than 1.5", if you want to have a near zero edge that is... https://www.calculator.net/triangle-calculator.html

    Nope, what is that? This issue is new to me because so far I had only used very hard and dense woods for my handles. Edit: the pic makes it look a bit worse than it really is. Here's a video in which I believe 3 coats had been applied. One more has been done since.

    The only time I managed to see the recalescence during the day I had to put the hot blade inside a 20 gallon steel drum. I heard oxy-cutting glasses work for this but I've never tried. Great idea writing all that up Zeb!

    Propane and butane evaporate quickly so perhaps these are part of the reason TruOil dries so fast.

    I did. I am guessing the added stuff is mainly to accelerate polymerization, not just solvents?

    That's a lot of precious info. Thank you gentlemen! I think I'm going to sand and go straight TruOil.
  23. Joël Mercier

    Seeking advice

    This is a mix of boiled linseed oil and TruOil. Perhaps I should try straight TruOil like Clifford says. I usually mix it to improve penetration. As for wet sanding, do you guys use plain linseed oil?

    For some reason, it never crossed my mind. Do you have a particular product in mind?
