Since this knife manufacturer specializes in making kydex products - the same material the sheath is made from, there is no excuse. Maybe I should have even give two stars, but hopefully I'll be able to fix the sheath myself. However, if I end up damaging it, this will drop down to one star. Review: Not snug - The sheath is not snug enough,I can't have it upside down for a downward draw, it's going to fall out if I'm running or jumping down. Maybe I got a bad sheath, I haven't read so far about no one complaining about that. The knife itself is sharp,the handle made it a bit heavy but still a nice knife. ## Features - ESSENTIAL FOR TACTICAL DEFENSE: 8.1" Full length, moderate size, exquisite and dexterous, Kydex tactical sheath, double-edged, sharp and practical, excellent tactical defense. - HIGH QUALITY: The blade is made of 440C steel, with real heat treatment + cryogenic treatment, high hardness (59HRC), good toughness, fine cutting edge, and very sharp.
