I assume you are talking about the SERE 2000 with the 3.625" liner-lock blade that I have seen you post.
Actually, I was referring to the 5" fixed blade model. There are signs posted at the regional and State Parks forbidding "knives, axes, machetes....etc". It came with the tec-lok which I hate. I removed the junk and rigged up a close to the body high-ride that is hidden by my fat belly and vest while I hike.
That is why I have rainwalker make high ride or horizontal carry sheaths for my Scrappers and others.
