Hi
As has been said we sheath makers do need to buy the knives & wait just like everyone else.
**now for a little somewhat off topic talk**
I make the trip every year to Blade to buy the knives to make sheaths with and this year drove/rode to Knob Creek, so that you do not have to send yours in, sometimes passing buy knives I would love to collect because I can only afford so many knives.
But the main reason I buy Busse, Swamp Rat, Scrap Yard knives, is that I am a HOG, a Fan, a Collector, or whatever else you may call me
. I collect/buy these knives because I believe in the product and the people, & especially Jerry. I call him my friend along with all the others I have met on this journey.
I have beat on these things & they do everything that Jerry says they will, & he stands behind his product 110%
So even if I did not make sheaths I would buy these knives. I like a guy that does that, & his influence is why I do the same, my sheaths and holsters are guaranteed for life.

As far as the finish, any sheath, I repeat any sheath could mar the finish if you shove the knife in & out of it enough, even the cardboard.
If I were to make the sheath loose enough as to never touch the finish the blade rattles around in the sheath & no one wants that.
If you want it to remain in mint/new condition please leave it in the safe, & do not use it.
I use tape on all my molding knives & the finish is un-marred on my own personal knives that I only use for sheath making, my users are a different story, but it is not the sheaths marring the finish
I can not guarantee if you shove the knife in & out of the sheath & use it that there will be no rubbing, no one can.
I sincerely hope this helps & has been a little informative. I did not mean to rant just to explain because I am not sure if people know how it works.
