  1. You can certainly do pattern welded blades with 1095 and 15N20 by hand. I did for a few years before I got serious enough to spend the money on building a press. However, it is very hard work, and I found that I wasn't so willing to do something bold or high-risk on a bar of material that I had literally spent 8 hours hand hammering on. This kept me from experimenting and trying new things. I also had to keep the billets rather small. 1"x1"x6" was about all I could handle. (Then again, I'm a pretty small guy) Many people would say 1084 is a better companion to 15N20 when you are just starting out. I use both, and can't say that I see much difference in workability. However, 1095 adds some complexity to heat treating. I can't really comment much on melting the brass. (Smelting actually means something else) I am a bit afraid of it, and have heard conflicting opinions on the danger. However, when I was younger and more foolish I did mess around with casting brass in the back yard, and remember seeing what I would now recognize as zinc smoke. Hopefully one of the more knowledgeable folks will chime in here for the both of us.
  2. I am good to go with my project, but would happily support extending the deadline to let more people have a chance to play.
  3. Looks really good for a first attempt. The "cumai" process is a pretty ambitious first attempt at pattern welding. Are the steel pieces pattern welded, or are you referring to the steel/copper/steel/copper/steel as the 5 layers? The fit and finish look good as well, especially for a first attempt. Is that a bit of lapidary work on the pommel? Cool story on the origin of the brass for the guard. Be carful melting down the brass though, the zinc in the alloy can burn off, and isn't good for you. A few smiths have died from simply burning off zinc galvanization from steel. Welcome to the madness
  4. Careful Jerrod. Using me as a sanity check is a pretty weak test
  5. Well, I like big bu... ...oh, we're talking knives. Maybe @Joël Mercier will chime in here as he has more kitchen knife design experience than I do. What I have noticed when I go real thin on a knife with a broad blade is that they feel unstable as I cut through thick food. Particularly with the tip on the board pushing the heel down through what I'm cutting. (chopping) If you have the time, I'd suggest you finish it, and try it out for a bit before you decide to start again.
  6. Thanks all for the generous compliments. Doh! Not sure how I messed up the link, but thanks for the catch and posting the right one. I've corrected it in the original post too. Yeah, this one came out a bit purple/plumb. To the point Jerrod always makes, I see a lot of variability in the oxide color when I heat blue these springs. They always go into my little lab oven (precise temp. control) at the same temp, and they are always well cleaned with acetone. However, I get shades from the classic spring steel blue to this more plumb color. I like the plumb more, it reminds me of the color of old rifles.
  7. I'm not sure I would claim the pins are domed. They are simply peened over with a tiny hammer I was surprisingly rusty at putting one of these together after a year off. I actually had to refer to a tutorial I did on this forum to remember how some of the steps go. It certainly made for a good argument to justify the time I spend writing the tutorial!
  8. Ooh, I really like that last one. I didn't even know Swordfish bill was a thing. Does it work like bone?
  9. Here is the first knife I have finished in quite some time. This is a slip-joint with bronze liners, bone scales, and nickel silver bolsters. The blade is made from a “Micro-mosaic” bar of steel I made a couple of years ago, but hadn’t made a knife from yet. You can see more about the steel here if you are so inclined: Micro-moasic The mainspring is 1075, and heat blued. I like the look of this, and it holds up surprisingly well in the pocket. My own knife still shows it blue color after 2 years of daily carry in the same pocket with my keys. The mechanicals of this knife are of my own design. I believe I have shared it on this forum before, but would be happy to put up the PDF pattern if y’all want. This knife will be my contribution to iron in the hat at the Bowie Memorial event coming up soon. Show up for a chance to win it Bowie Event Info Now for the pics:
  10. Just need to do a little final polishing on the bolsters, and sharpen the blade. Then this one will be done.
  11. There are some things you could easily do the the knife even though it is is assembled: A little time cleaning up the grooves in the bolster, and evening up the finish on the blade would make the knife look much better. As Alan said, an appropriate sized round file would make quick work of the bolster. Wrapping the same file with abrasive paper will let you polish it to whatever level of finish you desire. Taking some 400 grit paper on a hard backer, and stroking from the bolster to the tip would quickly even up the polish on the blade and make it look loads better. You'll be surprised how quickly the finish changes and improves if you stroke in one direction only. You could probably do both of these things in an hour. You could also use that hour to start your next project. That can be a tough choice, and I've decided to stop many projects before I finished them as well as I might have. Knowing what I know now, I would tell my past self to spend the extra hour to finish the knife if I were given the opportunity.
  12. It is something that has been re-handled, and probably reprofiled. It looks like it might have been a fillet knife originally to my eye. Is it pretty thin? Sadly, I don't think it is of much monetary value.
  13. I've not used one of those map torches like that, but I would be surprised if one of those could get that joint hot enough to braze. I suspect your suspicion is correct Can you get your hands on an oxy-acetylene torch for a bit?
  14. Getting close to finishing up my contribution for iron in the hat at the Bowie Memorial gathering...
  15. That is a fine contribution as it is. Nice!
  16. Yep body lead file. Funny, I have a couple that I got from my Dad's uncle. The ones I have are flexible so as to follow the contour of the body. I assume they were all that way?
  17. Looks like it's going to be a fine contribution to me!
  18. Wow. Glad to see you posting again. This piece is as inspirational as ever!
  19. Cool Looks like it's making good shavings.
  20. That is good news for the rest of us!
