Did anyone else notice the difference in quality between the DF sheaths and the S6 sized sheaths? The Cordura on the DF sheath is so much nicer than the nylon on the others. Is there any way to get the nylon line made out of cordura instead?

I have both sheaths and didn't really notice any difference. I will look at them closer tonight and see if I can see a difference.

how is the durability of these sheaths?

They are really high quality for the price. I carry my dogfather around most places and its held up really well. I would recommend them for someone who wants a quality sheath for a low price.

Yours came with sheaths ?

No they sell them at the company store.
