this is how to make it!
Step 1: What Kind of Steel.
I used a old Simonds file, but any file will do.
Step 2: Blade Dimensions
The main angle is 8 degrees, but the cutting edge is 35 degrees. As you can see it's 3.75 in long, and a little less than one inch high, and .128 or 1/8 in thick.
Step 3: Sheath
this is just some 1/8 in leather. than you'll need to take some thicker leather and put it around the outside border, (this is optional but will help to keep the knife from cutting the thread)
Step 4: Materials You Will Need:
one median sizes file.
a 3in by 2in square of leather.
and one heavy duty snap button
first you need to copy and past the pic that shows the sheath spread flat, and the one of the knife outline.put it on word and print it out. and then measure to make sure it's the right size. the sheath needs to be 3.5in long
Step 5: Slice and Dice
then put the template on the file and trace around it with a sharpie,now you need to clamp it down and cut it out with an angle grinder make sure to cool it regularly. when you come to the semi circle, cut from both corners to the center and the grind the rest out with a dremel, use a sanding cylinder.
Step 6: It's Time to File Down the Blade
the bevel is about 3/4in on a 8 degree angle. i used a disk sander but you can do the same with file.you will need a file for touch up work.
