I recently bought a D2 Spear point Ka bar Impact and was not too impressed with it. First of all, out of the box, the grind was very lopsided and I had to send it back to the factory because D2 is to much to put a new grind on with just bench stones. I found the micarta handles to be uncomfortable, something that a belt sander could easily fix. Basiclly, I am used to the fit and finish of BMs, and I would suggest a BM myself, but if you want a thick, indistructable knife, this one would be a good bet.
p.s. Ka Bar customer service is sooooo sloooooow! they get the job done, but it takes weeks and weeks. if you have a problem, try and work it out with the retailer, not Ka bar!
