That carve looks nice.
The NCO2 sword has a little detail to it. You can try the pattern to see a 3D preview of what it looks like on screen. Whether it will carve nice I couldn't tell you. I've never carved it. I don't think it would carve that good because of the size of the blade. I told that to the guy who I made it for, but he wanted it anyway. He didn't tell me how it carved. The bigger it's carved, the better it would end up being.
I looked up Ka-Bar knifes but there are a few different kinds. Something like that I would make to order because it's something that might not sell on the depot. I have a Marines knife on the depot that can be found by searching for "knife". You've probably seen that though.
