  1. Mf (the temperature at which all retained austenite is converted to martensite is about -100F for most (all?) of the knife steels that need this treatment. Thus dry ice should be just barely cold enough for that. However, liquid nitrogen is more economical for makers that do this frequently because you can keep a dewar of it for a month or so. There may be some added benefits to the lower temps of liquid nitrogen but that is more controversial.
  2. Really nice looking traditional santoku Sam! How does it work?
  3. Great to hear this Larry. I'll be in touch about a wand after you get this set up (and I finally get the power for the forge set up).
  4. Wonderful machine. I'm so glad it's still working and being used. I wonder if your workshop would fit in it :)
  5. I've used both WSSI and K&G with good results. Other folks I know also think well of both of them though opinion is pretty split on which is better.
  6. Cool! That does look worth the work.
  7. So sad, he leaves a mighty big hole. Excellent verse Brasikilt!
  8. Beautiful knife in all and that Aspen is really something. I hope your stabilization of it works well.
  9. Design and workmanship both look great!
  10. Beautiful design! I completely agree that a pro shot of this should be one of the highlights of your portfolio.
  11. The best, though most PIA way, is to fully shape and fit the handle slabs (and bolsters if any) in a removable way. Some people use bolts or temporary pins. Others use super glue. Then remove the handle, etch, and attach the handle permanently. Top makers tend to intentionally chamfer the tang/handle junction and/or make the wood be a couple of thousands proud of the junction. This is because wood will move anyway and an intentional junction looks better than what you'll wind up with after it moves.
  12. Chain saw damascus has definitely been done for blades. Both as the sole material and as the outside layers of a san mai.
  13. Both of the damascus are beautiful and that musk ox is just phenomenal! You've done the materials justice.
  14. This is what I wear most of the time I'm not doing hot work, especially when doing anything to wood with power tools: Resp-O-Rator. Light, comfortable, inexpensive. You have to breath through your mouth. Wears out after a while.
