  1. What happens 20 years from now? If they aren't permanently marked "not for use". Someone down the line could use these and get hurt? I was told by 2 different makers with 20 plus years making knives "Don't make a wall hanger that is not safe for use.".

    I'm not implying you aren't a really good maker. I am questioning making something that looks like you can use it but would never be safe for sport use. Most of the wall hangers I see are welded or riveted to a board usually a coat of arms of some sort.

    They really look like they were never repaired. A testament to your experience and attention to detail.

  2. Rich is right. Forging a torsion bar will make you feel like you did something! I heated one from a new Jeep to a reddish yellow and it hardly moved under my homemade 3lb hammer. I got my wife out of the house. She put the gloves on and held the bar in place. I went after it with a 10lb sledge hammer. Quenched by dipping in the slack tub for 1 second in the water 3 seconds out. Back and forth until the rod end was cool to touch. It has a wide chisel blade for digging hole and going thru mild sandstone.

    I don't know if an interrupted water quench (terminology?) will work for you. This is what worked for me at my shop. Please let us know how yours works out.

  3. Bowfishjim is there a place to send a sample to be tested? It may or may not be worth it price wise. Once you know what it is then finding the proper heat treat should be doable.

    Balancing price savings verses your time used is a difficult balance. I have a friend who got a lot of free 5160. Problem is It's 3/8" X 8" X 8'. Cutting into manageable pieces with a torch and grinding the slag off takes a lot of time. Buying 5160 in the size he needs only costs about $3.50 per blade.

    Of course you can't put a price on fun! I hope you have fun with it.

  4. I sourced all of the metal for my build at Seaton metal in Athens Tn. It was all scrap cut offs at $0.25 per pound. I also found 3 12 foot pieces of cold rolled 1/4" X 1 1/2" tool steel. Given the yellow ends and spark test I'm thinking 1095 or something around that. I'll be using the mystery metal testing in the knife section of IFI. I'm tempted to go back and get the rest 20 or so more new unused 1/4." X 1 1/2" steel. Best 25 cents a pound for 140 pounds of steel.

  5. You can skin a coon. Can you run a trot line? Must be a country boy! B) I agree with you on the ability to improvise a tool. You makin' a hat?


    LOL glad I wasn't drinking when I read that! Great tool!
  6. First red flag. :o You got the steel from a hardware store? <_< I've never seen blade quality bar stock at a hardware store. I'm thinking you were using mild steel. Second you are probably working the steel at the wrong temp. Using mild steel will hide this as it will move at lower tempuratures (knife quality steel is hard to impossible to forge at low temps). That plus heavy scale and the hammer will drive the scale down into the metal causing pitting.
    Lastly, hammer control and using good forge theory (start hot, finish at red) and using the "finishing heat" not to move the metal but to smooth it will help clean thing up. There are a few smiths who need very little cleanup, they are just that good.
    Start with good metal. Most aren't like me, I'm hard headed and like a challenge, so buy stuff that you know what it is. Study the methods to work with it, steels like 5160, 1070-1084 will be the easiest to work. Stay away from higher alloy steels as these can be difficult to work.
    Don't be afraid to post pics.


    Exactly. Practice your technique with high carbon. Like old leaf springs. They will give you a good feel for how to work a quality knife steel. Then go buy a good bar or rod and make a blade. I would try to use someone else's quenching techniques that works for them for the steel you decide on. You can always tweak your quench technique as you gain experience.
