  1. Nice looking knife but i'm am wondering why you just clayed the center of the blade and did not go for a softer spine?

    Bob


    Bob, I am starting to harden the spines on my knives. The center section is still soft.
    I have an old bowie I made a long time ago and I use it to drive through some hart pine kindling and the spine has mushroomed out quite a bit. I know this is abuse of the knife, but that is how I use it.
    I don't have a hardness tester but I think I have the spine just a little softer than the edge.
    I kinda like the way it looks.
  2. The first piece of damascus I made I used 0-1 and 1018. If I remember right I started with 5 pieces (3-1018 & 2- 01). There are a lot of different combinations of steels you can use, but this is the one I welded first and it will give a medium carbon steel and will have good contrast when etched. I think the key to get good welds is to have your steel clean and flat. I started out trying to make a small billet at first to learn to weld. If your son has success on smaller pieces maybe that will encourage him to stick with it.

  3. Just finished this folder. Blade is forged 52100 about 3" long acid etched finished, Titanium liners bolsters and clip, G10 scales. This one is going in the pocket of a soldier headed back to Iraq very soon. Thanks for looking,

  4. This is one I made after MS Terry Vandeventer did a demo. I think the hardest part of this is cutting the slot in the antler and getting it straight. This one has a brass pin and some little copper washers under the pin where it is peened. 100_1087.JPG


    Very good looking folder!! More pics please,,,
  5. what is with this normalize 3 times quench 3 times, anneal 3 times, temper 3 times. If 3 is good why is 6 not better and 12 best?

    Normalizing is a function of time AT temperature and then slow cooling not the number of times raised to temperature. According to JPH triple quenching has "some marginal effect on deep hardening steels like 52100 but otherwise is a good way to crack a blade." Tempering is once again a function of time at temperature not the number of times cycled thru the process.


    Perhaps you can try 6 times, 12 times and let us know. I only state what I know works for me. I have broken many small pieces of forged steel with different numbers of heat treatments and the "3" number produces the finest grain in the blades I forge.
  6. I think it is a good idea to start and stick with one type of steel while learning to forge blades. For large and small knives, I think 5160 would be a good steel.1/4" x 1" bar stock would be a good size to start with. I've made several knives from 5160, and it is one of my favorites, and it's easy to work with. I forge mine at about 1500-1600 degrees. Normalize 3 times, anneal 3 times, quench 3 times(in oil heated to about 160 degrees), and temper 3 times. A Google search for "forging 5160" steel will probably load you with information. Hope tis helps,
