big fan of the Nimravus! I remember when they came out. You had the choice of a kydex sheath or the nylon, IIRC. I have one with the nylon sheath in my truck!
I'm pretty sure the Stryker (fullsize though) was my first too. Might have even been a "first production run" version as we used to get a lot of those in (and people thought "1 of 250" meant they had #1 haha). I'll have to dig mine up. Pretty sure mine was a "teflon" blade and that most of that finish is now gone.
