Cool dye job on the sheath. I like that.
I'm not quite sure if it will fit, it might. but I love the GST Gossman Survival Tool.
I have the large one, that I recommend, but they also make a smaller one.
It's old timey, and unique at the same time. Very handy.
It's basically hardened steel. Harder than your knives. You run it along it as if you are sharpening on it.
it touches up your dull blade. Less than a stone, but more than stropping.
It's also a wedge for spitting wood. Scraper, and striker for your firesteel.
I'm sure there are a Ton of uses. I like it alot.
I'll look tonight if it will fit in my 15's sheath. I'm betting they are the same?
