Hikermor, I've got a Stiff K.I.S.S also and freakin love it. I don't know why they stopped making it, and looking around their website now I don't see a comparable replacement. It's a shame. Out of all my knives, I tend to carry that one for weekend backpacking and hiking. Even the fixed Ritter, which I also love, I only tend to bring on hunting trips.
It seems a tad big for a neck knife, but that Buck Smidgen seems to be awfully close to perfect for that, might have to check it out. Thanks Northerner for the heads up!
