Resurrecting the thread because I finally bit the bullet and started on a kitchen knife, so you all get to watch me stumble and fail. Here's my pattern in plywood and the result in steel:



Meant to be a gift, if I'm not too embarrassed by the end result. It's CM 154 steel, far too thick at 1/8", but here we are.

Next up: putting on a bevel using a belt grinder. Made myself a little scrap wood jig/guide so I don't burn off my fingertips any more than I already have. Stretch goal: make some mosaic pins.

Thread necromancy time. Put a crappy bevel on the blade, had it heat treated, made some pins of steel tubing filled with black epoxy (mosaics turned out awful), and roughly shaped stabilized maple into scales:



Next up: clean up the oxides from the heat treat, attach the handle & pins, shapeshapeshape, etc. But I don't want to make this a log so I'll just post the finished result. At this pace, I'll be done sometime in... November.

Well in that case :v:

Cleaned up the oxides from the blade and put on the handle + pins. Here it is, last chance to stop:



Epoxied and clamped:



And how it looks while curing, covered in epoxy goop due to handling:



Of course, I managed to drop it as I was unclamping the whole thing :downs:

I don't think I'll get to work on it any more until the weekend, which is just as well because I've learned not to push my luck while things are at least moving along.

^ very cool! Really digging the knurling.

Latest in my ongoing saga: put a small secondary bevel on the very edge and shaped the handle:



I'm also building an accompanying gift box -- you can it in the upper right corner. That became even more loving irritating because of the splintery nature of the wood I chose.

Up next: sharpen the edge, polish the blade (hopefully removing some of those scratches), wax the handle, and... that's it? I think.

And finally, some glamour shots of the finished knife and box:











The box is made of some raw, driftwood-looking maple (because the handle uses maple too) which I will never use again. It splinters like crazy, even in parts where it didn't have the knots, which made the box a really goddamn annoying part of the project.

Anyway, things I've learned/would change:

  • Thinner stock would've been a much better choice, as the final profile is more convex than I'd like
  • You have to be very firm and even when grinding, else you're left with scratches that are really difficult to remove. You can see them in the pictures, although the worst offenders are strategically hidden
  • Grinding the handle & pins was much easier and faster than I thought it would be. Getting a smooth, scratch-free bottom of the handle... not so much.
  • The CM154 steel takes a really good edge (which I had professionally done for fear of wrecking the blade)
  • Respirators are a really good thing, and I hope I used them consistently enough to avoid contracting black lung or some other Dickensian disease

Overall, I'm happy with my first knife ever, and I'll probably do it again but... This poo poo is hard, yo.

Nope, wasn't as refined as that. I took three cutoff pieces and cut/sanded them to the shape of the blade, then glued to the bottom of the box. Here's how they look under the flocking:



Pieces A and B were easy, just straight cuts. Piece C needed a scrollsaw and spindle sander to get the right curve, but none of it was terribly complex. Used the same approach on the handle holder/notch.

But if I were doing it again, I'd try to do the whole interior out of one piece. If you look at the original picture, you can see seams where A+C and B+C joined together, and I wish I had avoided that. I figured the flocking would make it uniform. No dice.

Hello knife thread. I just started getting into knife making about a month ago. This is my second attempt I think it turned out well.



I did not really take any pictures during construction. The knife is 3/16" thick 1084. I did the heat treat myself in a modified grill with lump charcoal and air being blown in from a shop vac. Hand sanded to 600 grit. The handle is Bolivian rosewood with a Danish oil finish.

Wow, really nice!

Knife #4 I made this for a friend she picked the scales. They are spalted and dyed maple. I used a water based poly for the handle.

Don't think I've ever seen dyed scales -- pretty cool effect.

Had steel left over, friend saw my first attempt and reacted with "I want one!", so wife suggested I make knives for said friend. I decided to go with cheese knives:





These are nos. 2 and 3 I ever made, so uh... scratches and dishing are still heavily featured. But they're well-received, so I'll just keep going and hopefully improve.

Until I lose access to the belt grinder :-/

I'd totally contribute more but no longer have access to the belt grinder and I'm about to lose access to a garage :( I don't think the wife or neighbours would be fans of me filing away in our condo or on the balcony.

I actually came across this while looking for some leatherworking ideas, but if you ever want to feel completely inadequate in this knifemaking business, just browse this dude's thread:

http://www.bladeforums.com/forums/showthread.php/798829-Knives-from-the-workshop-of-Roman-Blaha

Anyway, how do you think he pulls off these peened-yet-flush pins? I haven't tried peening, but it seems to me like they're far more likely to be proud instead of flush with the handle:



Do you need some kind of fancy press to pull that off? Fully shape the handle and pins before applying epoxy? I have no idea :psyduck:

For that matter, this is a really neat detail as well:



Is this a... rounded off rat-tail stick tang? Again, no idea how to pull it off short of shaping and finishing everything before assembly.

A drill press and vise could be extremely useful in drilling the tang and scales for your pins (if you plan on using them). You might be able to pull it off with a handheld drill, but getting them nice straight... it's tricky.

It's the opposite of the forging or stock removal approach most of us have to take, but I thought it was a neat overview of CNC-based manufacturing:

Those places, in my experience, also tend to be owned/staffed by grognards who have never used email and can barely stand the phone. Asking in person might be your best bet for getting in actual answer (which will probably still be a no, sadly).

I actually liked making handles and pins, back when I dabbled in this hobby. I treated it like sanding in woodworking: it means you're almost done!

On the topic of handles, this guy's videos popped up in my YouTube recommendations and whoa:

steak knife for myself (didn't put tons of effort into refinement, there's a few rough spots)
hunting knife for a friend
chief knives


the two on the left just need sharpening, the two on the right are sitting in a coffee etch overnight

Digging it all, esp that brass bolster. Is it a solid piece you drilled through for the tang or did you fold it over, glorious Nippon katana-style?

Is there an option for a belt grinder at around £200 (UK)?
I don’t have the budget, space, or time to dedicate to knives to justify a 2x72 fancy thing, but currently only have a combo 4” belt sander thing, so would like a bit of an upgrade.

I appreciate such a machine will be limited, and that’s fine. I’ve made 3 knives in the past and it’s fun, but not something I’ll take super seriously.

To follow up on Ghostnuke's comment, this just popped up in my recommendations:

Granted, it's sponsored by one of the Canadian equivalents of Harbor Freight, but the tool itself is a no-name generic 1x30.

Conclusion: yes, you can make very decent knives on them. I just imagine you'll have to go slow and get some decent belts.
