I originally posted this in the Custom and Handmade knife subforum, but given the kind of work the customer put this through, I thought it also appropriate here.
My original post on the subject:
I was contacted by a flight engineer on an AC-130 gunship about a knife to carry with him. He's about to go do his SERE training and wanted a good knife to take, as well as just general usage. He gave me some general parameters of what he was looking for and a blade size, 7". I sent him a quick sketch:
He approved and I got busy. I started with 3/4" round 5160 and forged this:
I cleaned up the profile and it looked much more like the sketch, even though I didn't have to take off much steel. After cleanup grinding:
I soaked it in vinegar to eat the scale off the blade, filed the bevels, and triple hardened it in veggie oil:
After tempering three times and cleanup, I used a new style of cord wrap I've been working on. It uses an underlay and an overlay of contrasting parachute cord, the underlay intact to build up the size of the handle appropriately and the overlay stipped of its core cords to lay flatter. The inspiration for this style of wrap came from a Mongol saber I saw recently in a museum exhibit on Ghengis Khan. I looked at it closely and fixed in my mind how it looked, then played around with paracrod until I figured it out. Fairly simple, really. After each layer is wrapped, it is sealed in cyanoacrylate (superglue), which wicks down into the fibers and hardens, forming a solid composite material in place.
In this case, the underlay is olive drab and the overlay is desert tan. After that, a Kydex sheath with a pair of MOLLE clips, sharpening, and it's in the mail on its way to him.
The spine on this is 1/4" thick, yet because it's forged into one long bevel (essentially a full flat grind, though it's forged and not ground), it still has a bevel angle that cuts well.
I'm looking forward to hearing how this knife does with the SERE training. Several more in this basic style are in the works for some Marines.
And now the after-report:
The airman who ordered this knife completed his SERE training. With his permission, here's what he told me about using it:
"Ok, so im back from SERE school and it was rough. Learned alot though. My wife sent me the knife and out of the box i thought it was awsome. Sheath is very cool and functional. knife stays well with tension. The clips work very well on a web belt as well as MOLLE attachments on my vest. The knife itself is very beefy. I was not able to take pictures because alot of the training is classified and i was not able to bring a camera. I can say that the knife worked like a dream. We had many tasks during the training that involved a good knife. They issued us all bolt knives but i chose to use yours even though i still had to lug around the bolt knife as well. cutting tree bows down was very easy. I probobly cut down about 150 bows for shelters and camo. We also cut down alot of tree bolts for fires. we used large branches to beat the knife through the the tree bolts to have smaller pieces and the knife went through like butter. finished way faster than the guys with the bolt knifes. probobly went through about 20 bolts of wood. the tip worked real well for breaking down wood too. I also used the kinfe to start fires with a metal match and cut down alot of brush while evading. The knife worked like a dream and i had alot of guys ask where i got it so your cards went to good homes. Im sure you will get a few calls. This knife is definately staying in my helmet bag when i fly. Great knife. email me with any specific questions you have. Im still telling alot of people about it. Oh and the knife is still as sharp as it was when i got it in the mail. Thanks again. "
I had to look up that a "bolt knife" is the USAF-issued survival knife, named that for it's bolt head-shaped pommel. I also hadn't heard the term "tree bolt", but he sent some pictures to show me.
Folks, I was surprised to see his comment about the blade being as sharp as when he got it after putting it through the kind of work he described. I was hoping it would serve him well, but this is by far the hardest use one of my little blades has seen and it performed better than I had expected. That's why I made that part bold.
I'm pretty proud to have made a blade that would do that well.
I asked him about how the handle had been both in comfort and in durability. His response: "I really liked the handle wrap as well. It fit good in my hand even when i wore gloves. It was very cold so we wore nomex flight gloves as well as calf skin leather gloves. Very good grip. also the sheath worked very well and was very quiet with the knife in as well which was good because we had to do alot of evading."
A couple of pics he sent of it on his bag:
This is not the last primal/tactical knife I will be making. I have four in the works for active-duty military and hope to have more serving our armed forces in the future.

I'll think about it.
