I echo judge. Nice knife for the price. handle isn't great, but very effective for concealment. The first Kobun I had, the guard came loose as described; I sent it to CS & they sent me a replacement, saying they had fixed the flaw on current knives. I haven't had this problem since, but I haven't used the knife mucc. The first one I used as a camping knife, and it worked very well - strong, light, sharp. If you are considering it for defensive purposes I would suggest the serrated version - I used mine for all kinds of utility tasks, and those serrations are savage, just mean.
BTW, I got mine new for $70 some time ago, and I'm sure you can beat that used.
