If you need a good backup-style fixed blade that can flex into the neck and boot knife roles, at a great price, you won’t do much better than the BK-4 from Camillus. This mini double edge dagger features a 2" blade and 4.5" overall profile, not including the neon green lanyard. Each knife is made from titanium coated 440 steel with a finger hole for a secure grip and bottle opener for added utility coolness.
