I agree the retention is insanely way too much on this knife. Now I’ll be the first to admit when I do something stupid, but I bought this knife for bail bags for the family so everyone had a knife/ 72 hour bag they could keep in the car for emergencies, so this knife isn’t even intended for me. And while theres no excuse for a lapse in saftey this sheath simply doesn't add to it. I tried breaking this sheath in for multiple days leaving the knife semi sheathed like suggested to loosen up the retention but after that still ended up having put a lot of pressure on the sheath with thumb release or otherwise so much that the blade jumps out uncontrollably. I ended up slicing my left thumb because I choked too much on the scabbard and recoiled back and forward in an attempt to control the release of the blade. The blade needless to say, (I know from first hand experience) it’s extremely sharp. So all the toughy wanna be knife aficionados out there, consider this: even with military training or otherwise, would you put that much retention on a gun holster and not expect bad things to happen? That’s without someone making a mistake? My Chris Reeve knive in the spec op sheath? Loose, but I can shake the knife violently and it stays retained until simple thumb snap and the blade drops free. Benchmade bushcrafter? Has a loose leather sheath, I can shake that violently and it retains the knife, until a simple thumb snap releases the blade. The esee knife is great but maybe they ought to relax their retention boner and have a sheath that isn’t dangerously hard to pull the knife from. And those other sheaths? No break in, no jolting knife release, butter smooth. Maybe esee should get the sheath rivets a few thousands longer or put a tension adjusting screw in all their sheaths. Just saying. Anyone considering buying this knife? It appears to be an impressive moderately price winner. The sheath? If its got a retention stiffy, throw it in the garbage and look for other options. Don’t risk your safety or worse, someone else’s, I don’t care how strong or trained you are. Needlessly dangerous is needlessly dangerous.
