    I started machining my hoddy knives. I work at a small machine shop that is nice enough to let me jump on the 2 axis cnc once in a while.

    About 4 years ago I made a 23.5 inch cpm3V chopper called the grinch. It was 0.220 thick and 2.3 wide. The handle could be handled two handed but was shorter.

    Long and the short is I started to explore making a faster, lighter and backpackable grinch.

    I drew up a design in bobcad and made it. I recently finished it and have been testing. I live up north and it was 0 degrees this morning. I had it hardened a 58 59RC because it the lower temps it will endure.
    When i go winter camping i have a 24inch saw and a cutting impliment. Mainly cutting 5 to 6 inch and under wood.

    Well it is handling as expected. 0.150 stock. 1lb 6 oz. 23.5 inches overall.

    Nice work. The contours on your 2-handed Grinch look well-thought out, trading out the possibility for a mid-hilt grip for solid holds on either end. It also looks like a beast of a chopper....and given that the time of year you want to use it, that makes the Grinch the best Christmas Chopper around. What a way to put the fun back into Christmas chopping season!

    that really is a cool build, congrats... I've been looking at using some cpm4v which is essentially the same stuff... I was concerned about the 1% carbon making it too brittle/carbidy for a chopper. So I kept swinging back to 3v at 0.8% (or even the super low cost, 80crv2)

    how hard have you pushed it? how much abuse is it taking? Did you cryo it?

    I had bought the 2x23.5x0.150 to make some edc size knives. I had machined some out of CPM3V and was going to compare to V4E.

    I ended up randomingly drawing that chopper and making it.
    That said I 3V is my favorite steel in that section.
    I wanted to see if it would fail or chip real bad.
    I did not do the heat treat. I have had very good luck with peters. I did request a low temper but it was around blade show and I think they were low staffed and did the standard heat treat with cryo.

    The other chopper picture is 3V with the low temper 60.5 RC. I beat that as far as it can be beaten.

    I do plan on running this hard. I have already started but it will be a ultralight selection. I also wanted this to have really good edge holding as far as wood working goes.
    I figured it the comp choppers are using it at 62 64 RC. It should work good.
    With the RC 58 59 is is actually pretty flexable.
