After trying a number of ultra light knives I've been very happy with my current knife setup (Gerber Vital), but as a gear junkie I'm always looking at new gear and tweaking my backpacking setup. The Kestrel and Tyto knives have caught my eye (I'm probably just too bored in the off-season). My question is....how secure are the knives in those sheaths? I noticed there is no cross over strap to ensure it won't accidentally come out. Those knives are soooo sharp I would never want one to come out of the sheath in my pack, yet it seems like it could happen. Just curious if others share that concern and/or if you have significant experience with them what have you seen. If I bought one, I might consider adding a light bungee strap or something to keep it in the sheath. Just better safe than sorry in the backcountry.
