Dennis, I just now found this thread from your post in the "Sheath Thickness" thread - you did GREAT!!! With both the Bowie and the sheath. The sheath WIP is really good. I've bookmarked it for future reference. I need to make a sheath for this Bowie I did.
For me, Bowie sheaths take a bit of extra attention because of the guards. You have to think about that issue in the early planning stages and build around it.
