Support BladeForums! Paid memberships don't see ads! I don't see much talk about hollow handle CRKs lately. It's a shame because they are all so beautiful and on occasion, you can find them for $500 or so, which seems to me to be a steal given raw materials, craftsmanship, and rarity! My favorite are: Project 2 - reminds me a K-Bar knife shape, but in higher build quality Al Mar Collab - I've always liked looking at Al Mar knives in various knife and tactical mags growing up. Never owned one, and I'm so spoiled by CRK folders that I don't think I'd be happy with one of the production Al Mar SERE knives. But the Collab CRK OPK would tickle my nostalgia button! Aviator with sawback - probably the coolest and most practical. While I love the Project 2s, they are pretty big and from a practical standpoint, it seems like if you're carrying something that large out into the bush, you'd be able to carry a separate survival kit. Whereas the aviator is like a compact, one-and-done type kit. Also looks really cool! Skinner - big, fatter brother to the aviator.
