Second update: With regards to the tanto Nimravus, although not exactly what I wanted, it works great for general use and over time with sharpenings, will turn into an ever better blade shape (IMO).
As for the black short Ka-Bar...I'm happy that I'm not afraid to do use it as a general camp/hiking knife, and for that use, it's turning out great. What I'm not happy about, though, is that I'm having to re-profile the edge on one side. One side is right around 20 degrees while the other side is about 30 degrees (possibly a tad more). Re-profiling has taken a small bit of time, but really it's not that big of a deal.
The handles on both knives are very nice feeling for me, though I do have somewhat small-ish hands. The Ka-Bar's handle is nice and grippy and I'm had no problem with it when it's wet. The Nimravus's texturing on the aluminum handles adds to the grippiness, but after a while of using it, can be a little rough on the hands, but it's nothing that's painful or problematic...the jimping on the spine is great, though.
Also having a 3/4 of an inch less blade than the Ka-Bar, the Nimravus looks and feels like a much bigger knife to me. The thickness of the Nim is going to lend well to food preparation and other slim jobs than the Ka-Bar...In addition, I think the Ka-Bar's grind starts a bit low (below the halfway point).
All in all, both knives aren't bad, but they do lend themselves to different applications, and I've got no problem carrying both if wanted.
