    Need help with bent Nakiri at handle

    Place the blade flat on a sturdy table with your palm close to the handle, push handle to straighten, if that doesn’t work then turn it over. Hoss

    Need help with bent Nakiri at handle

    If it was bent with the handle on, it’s best to try to straighten it with the handle on. Hoss

    How did you get here? On this knife journey that is.

    Stole a pocket knife from my scout master when I was 12 years old, thought I really needed it. Made my first knife when I was 13. Been making knives for 42 years now. Made some kitchen knives at age 17 and my mom threw them away because they didn’t cut very good and they stained because they...

    I Tested the Edge Retention of 48 Steels

    Predicted wear resistance of 15N20 would be close to 8670, maybe a little less. Hoss

    I Tested the Edge Retention of 48 Steels

    Heat treating takes a big jump from a poor heat treat to a good heat treat. There is a smaller jump from a good heat treat to a superior heat treat. Hoss

    There should have been a warning in the title stating some of the content might be offensive to sensitive viewers. Hoss

    I Tested the Edge Retention of 48 Steels

    There might be a conflict of interest for a company to buy their own machine and do their own testing and show superiority of the knives they make. Knife testing is different than steel testing. Hoss

    Who has a Global knife that we can test to see if the results can be duplicated? Hoss

    I Tested the Edge Retention of 48 Steels

    This wasn’t a test designed for kitchen knives or kitchen knife steels. It was posted here because Larrin is a member of this forum. Hoss

    You should make test coupons from the steels that you’ve seen the most improvement with your advanced heat treat. Even with the aggressive media being cut/tested, there will be a separation from the standard heat treat. Then we can find out how much of a measurable difference there is. Hoss

    I had forgotten how good those articles are. It was good for me to reread them. Hoss

    I Tested the Edge Retention of 48 Steels

    I apologize for being so offensive. @RDalman and @bryan03 are highly respected knife makers who make excellent knives. I don’t think this is the best test for simple carbon and low alloy steels because it uses far too aggressive media. We need to devise a better test for all of the most...

    I Tested the Edge Retention of 48 Steels

    This wasn’t a study of heat treating like some of you are trying to make it in to. Wear resistance is controlled mostly by carbides and hardness which is controlled by the chemical composition of the steel. Most of these test coupons were heat treated using the standard recommended heat...

    Looks like a nickel layer to me. Hoss
