  1. Thank you. I made a vertical tank but have been hesitant to use it until I had better understanding of this. I knocked over my horizontal quench tank. It took four hours to properly clean up. It gave me new motivation to do the further research for the vertical tank.
  2. For quenching, there is the Leidenfrost effect where a vapor gap occurs and the cooling rate is relatively low until the temperature drops enough for wetting. Upon wetting the cooling rate increases significantly. With metal thickness on a bevel, and this effect, I have seen natural hamon occur in a horizontal quench. In a vertical quench the Leidenfrost effect causes the wetting transition to progress up the knife or sword, so in my mind this means the higher up the piece the slower the overall quench rate and therefore an influence on the hardness from tip to end. Convection in the quenchan
  3. Your comments are much appreciated.
  4. The Ridgid brand hardened up very well. If I find out the exact alloy I will use it often.
  5. I decided to try my hand at a pipe wrench knife over the weekend. I know a lot of these have been made, but it I enjoyed the process. I’m thinking of making one or two more. Maybe a dagger. What do you all think?
  6. Sleek. It makes me want to use it just looking at it.
  7. Using your own knives for a short while may help your design work. It is important to know what works, instead of what just looks good to your eye.
  8. If I may chime in... Learn everything you possibly can about metallurgy. Alloying elements, what temperatures and other contributing factors affect the structure of the steel, TTT, etc. Find out what books are used in bachelor's degrees, and later masters degrees in metallurgy, and read them. There is more to knife making than almost any other career (or hobby), if you take the time to learn it correctly. Practicing the art is only part of it. You will never regret knowing the technical aspects. From steel you make from the ground yourself, to the latest high alloy particle steel, learn i
  9. Thank you Alan. Dustin, I found this rusted and beat up at a swap meet for $8. I shaped and hollow ground it, put it through the heat treat and temper cycles, hit it with a wire wheel, followed by a sisal wheel with black rouge. I was careful not to blur the lines. The tip line looks blurred, but it is just the photo.
  10. I only have one dog. She's not aware she's a dog and doesn't spend nights outside so I don't have to worry about her. They roam my area in packs of 8 to 10. A couple of the pics from that night have three in the frame.
  11. Taken Christmas night 2016 outside of my back fence. Infra-red game camera at night. Healthy coyotes in my area.
  12. Hollow ground with a temper line not yet developed.
  13. I finally got around to finishing this. Not the best pic, but its the only one I have of it. Ebony, nickel silver, pomele sapele.
