The HEST has become my primary knife for my overnight trips, and I love it. The only problem that I've had with it is that it rattles quite a bit within the sheath (and I've even tried moving the screw to the tighter configuration). Is this a common thing? The lock up is tight... but the sound can get a bit bothersome on hikes. I'll probably end up getting an aftermarket sheath made for this... but I was just wondering.
