I've been wondering ever since I received my Izula, how well the small rised plastic molded restraints in the sheath hold up long term. Been using mine for about 3 months now and I can tell they are both wearing down a bit. Since this is primarily my neck knife it is a bit of a concern seeing how you wouldn't really want the knife to eventually fall out. That could be an accident wainting to happen. Or even worse yet...... losing my prized bush knife. Does anyone have any long term use with this sheath system? If so, how does it fair? If not... any suggestions? Thanks in advance for any feedback. Look foward to seeing what you guys have to say.
