    I have been wanting to make some of these things for a while. I had a few guys come into the shop and we got to talking, I find out one of them is a "blade smith". After some discussion on material he suggested O1 tool steel.
    I got busy drawing them up

    Then over to the machine

    The first few I cut were aluminum, easier to proof the program and set up in something cheap and easy to machine.

    Found out the ball groove was a little deep, so I backed it off and cut some steel.

    And since I went to the trouble to make one, I figured I should at least make 12.

    I also got a piece of steel from the blade smith that I was able to get 2 out of.

    After the flat work was done came the fun part, fixturing for the angle.

    I don't have any pictures of the backside of this fixture, but the backside is machined at 13 degrees and the two sides are square to the machined angle. This way I can hold the fixture in a vice and cut the angle with a regular end mill.
    The blade was held in with an aluminum strap that bolted to the fixture and one bolt down on the ring, it repeated on every blade, giving me a nice centerline from the groove to the tip.

    Then I heat treated them and ran 3 tempering cycles. After heat treat they were 62 Rockwell, after the tempering cycles they are between 56 and 58 Rockwell.
    After heat treat I ground a primary angle on the blade, leaving a little material in the middle.

    Now I am waiting for cerakote, half will be tungsten gray the other half will be graphite black, once back from cerakote then I will grind a secondary angle and put an edge on them.

    The piece of material I got from the guy helping me was damascus that he forged. I didn't put edges on these two blades as they will be more for looks and conversation pieces.

    I also learned a little about kydex, this stuff is pretty easy to work with.

    Very cool, and nicely done. I am a blacksmith by trade so I always look at things from a manipulation standpoint rather than removing material nor do I have the ability to draw fancy pictures on the computer. Always cool to see how a different mindset works. I just hit it with a hammer till it looks good ;)

    That's cool...ever thought about working with the handle a little bit more? Seams like with a good jab your hand could slip if you don't have a finger in the hole.

    Thanks, you won't find to many big hammers in our shop.

    This was the design I found and really liked. So far playing with them, I haven't had any real worries about my hand slipping, there's a pretty good distance between your hand and the sharp part.

    I have some pretty big hammers :) I have a Nazel 4B (350lb) in my shop here in Washington as well as 4 other smaller hammers. My big hammer though is in Idaho at my dads place, A 750 lb Chambersberg. The entire machine weighs about 33,000 lbs. Its about as big as a small hammer gets, from there they kind of get out of the range of practicality for a artist blacksmith (not because you cant do cool stuff with them but because the cost to install and run them gets prohibitive

    The Damascus blades are very cool.

    These need a final edge and they will be done. The graphite black cerakote is an awesome color!

    Thanks BillCoe.... We do some civilian sales but mostly Mil Contracts.. were trying to branch out to more standard sales and have been working on some designs that don't have quite the seriousness of most of our stuff.. a good part of what we make never makes it to the website.. once in awhile a picture will hit our facebook page submitted from someone using it in some not so nice of a place.. Thanks..

    for the record Nick B reached out to me as asked and now has a better understanding that just cause you can, does not mean you should..
