Say hello to my Lil Friend. Literally. At just 3.375" long, Boker's Magnum Lil Friend micro fixed blade isn't just small enough to slide into your pocket, it's small enough to slide into the wallet you slide into your pocket. Or more probably, given that the knife comes with a necklace and sheath, small enough to wear around your neck.
Amazon reviewers report that while the 1.38" blade is super Lil, it's still "sharp enough to shave with." Lil Friend's ergonomics and G-10 handle also get positive feedback for grip and ease of use. The blade is made of 440 stainless steel.
