Since it's forged, the fullers don't really affect the simplicity of it. Simple fullers are fine.
I'm not a fan of paracord wrapped handles. I like real handle scales or a one piece handle. A handle like the Tamang or Tarwar would be a sweet option.
True, it was made as a matter of what was available, however the design is a great one. Simple, straightforward, effective. It bears repeating. Simple is good. Form follows function. No frills. All go, no show. Businesslike. Spartan.
I could live with a little less curve to the blade, but I like your design just like it is. In fact, I prefer it. You did a great job on a 5 minute sketch. Had I drawn it, it would have looked like it was drawn by a monkey on crack. Or worse.
You should design knives for HI. That one would go great with an AK Bowie.
I think we've found the next great HI knife design. I think this one would be a winner, like the Tamang. Please, Yangdu, get the kamis to make these.
