Old thread revived here, but I'm going to offer up a contrary voice. The Havalon #22XT blades have/do work best for me in a replaceable blade knife. I currently use them with a Goat Knives handle for its utility, but if I were to do it over I'd probably buy an Ovis Scalpel.
Most of the time folks snap blades its because they are doing something with them they're not designed for (popping joints etc). Simple solution is to bring two knives - a light fixed blade for camp work and the afore mentioned joint popping, and a smaller-bladed scalpel for skinning and such. YMMV but using the right tool for the job has always served me well.
