Personally, I found the sheath to be appropriate, and I appreciate that I can draw the blade safely without forcing it (I have kydex that is so tight it is dangerous), yet retains the blade well (I have kydex that is so loose it is dangerous). I was just thinking that this one hits the sweet spot.
I have to tell you, however, that beating the Griffin X through a fallen pine tree left some marks on the blade... Rest assured, however, the marks on the tree are much more pronounced...
All that said, if there are folks out there who want a user but also wish to avoid scratches, in my experience a patina will mask them quite effectively. Therefore, it may be viewed as a transitional aesthetic of the blade.
Thanks for your post and for making the knife.
