I've always wanted to check out an all-titanium knife and I've had the chance as I recently aquired two Pat Crawford all-titanium neck knives. An all-titanium KFF and a little all-titanium drop point.
First, let me say that titanium makes the PERFECT neck knife. I've owned them all, (neck knives), and I have to say, I still can't believe how light these things are! They truly disappear when they are worn and that is what you want when you "neck wear" a knife. You won't believe it until you try it, (the Kydex or Concealex sheaths that they came with almost weigh more than the knives!). Also for you defensive knife fans, they WILL penetrate flesh EASILY!
I have heard all the stories about titanium over the years, (no edge holding whatsoever), but believe me, these things are more than adequate! They take an incredibly sharp edge and are on par with a lot of carbon steels, (IMHO), in edge retention. I've cut lots of meat and veggies with these things and they get the job done. As a plus, they are simple to re-sharpen, (I use diamonds and a smooth butcher's steel to straighten the edge). All this and they are tough as nails and completely rust-proof to boot! No, they won't chop logs apart and they won't cut through staples but the edges are adequate as hell! I don't know why I waited this long to get one!
