A buddy of mine had a firestorm. Tough little knife. The blade was a little soft, but the knife was used as a thrower on multiple occasions and never had a single problem. The Carson flipper was great with the super slick bearings in the Firestorm.
Most blades that are secured to the frame by a screw of some sort come loose fairly easy. Even after using the knife as a thrower the blade to frame fit never had any play in it. The liner lock never lost it's composure. He got it about the same time I obtained a Cold Steel Zytel Ti-Lite. I only wish my knife had held up even half as good as his.
The only reason I never bought one was because the blade was 420 Stainless. However, his blade seemed to hold up to everything mine could, and if I could go back and trade him I would have.
