Anyone here have experience with Ka-bar folding knives? I recently bought a Ka-bar 4051 folding knife with a D2 blade. I had a small problem that I was able to fix myself but I had emailed Ka-bar about it. They told me the knife was discontinued and no replacement parts were available so they would replace it with a different model. Since I had corrected the problem I declined. I was very happy with their customer service. I think I like this knife and I know I like this company and I'm sure I will buy more of their knives. Their customer service was top notch. My question to you guys is: are their knives good also? Mine hasn't yet been used enough to form an opinion.
