This one went out today to a retired SWAT officer who works at a military school and does survival training with the cadets, the Boy Scouts, and Venture Scouts.

He wanted a similar pattern to the SERE knife I made for the airman at the beginning of the year. I forged 3/4" round 5160 into a blade approximately 8" long with a spine 1/4" thick and a cross section that tapers from the spine down to the secondary bevel (or as some folks call it, the primary bevel. :D ). Essentially a full flat grind except that it's forged and filed instead of ground.

You can see how closely it was forged to its final dimensions. Not a whole lot had to be ground away to clean up the profile and not a lot had to be filed to complete the primary bevel.

After my typical triple quench in canola oil and triple temper cycle heat treatment I use on 5160, I cleaned off the oil and cut out a slab of leather for either side of the handle and cut a hole to match the anchor hole drilled through the tang. A little patience, a little tape to temporarily hold things in place, and I started wrapping the hemp cord around the leather. It anchors at the end of the handle through both the steel and the leather. Then I tied the two-strand Turk's head knot a the front of the handle using black cotton cord.

And then plenty of amber shellac to seal things and create a natural composite material in place on the handle.

After the shellac was nicely dried and hardened, I sharpened it to shaving sharp (giving it its secondary (or primary :D ) bevel. Here's what it looked like right before being packed away and dropped in the mail.

I would consider this to be part of my Primal/Tactical lineup, but leaning a bit more on the primal side of things.
 
Wonderful knife..I like the look of the handle to blade connection point..I bet it balances nicely!
Next time I am in Tejas can I visit the shop?? I have family on Canyon Lake.
 
Baldtaco-II - I use the shellac largely as a means of using a natural sealer with natural handle materials. Shellac is made from insect hulls dissolved in alcohol and when grain alcohol is used is non-toxic to the point that it is/has been used to coat pills and candy. This is made with denatured alcohol so you won't drink it, but once it dries and the alcohol has evaporated there isn't anything toxic about it.

I use synthetic sealer (Minwax Wood Hardener) with synthetic cord wraps and natural sealer with natural cord wraps. Just 'cause it seemed to make sense. :)
 
Storm Crow, hey – Yeah, I'm aware of the properties of shellac. Continuing a theme is a good enough reason I guess. I've seen your work at a couple of other places. That's a good looking amount of shop space you've got there.
 
Looks like a useful design. ;)
After my typical triple quench in canola oil and triple temper cycle heat treatment I use on 5160, I cleaned off the oil and cut out a slab of leather for either side of the handle and cut a hole to match the anchor hole drilled through the tang.
Just curious, any idea what Rockwell hardness you're getting from this process?

No Rockwell tester, so I can't give you any kind of number. I know that the blades hold a good edge while cutting hardwoods, but are easy to resharpen, so that may give you an idea of the Rockwell.
