David Brown’s kydex sheaths hold the knife by squeezing the blade itself. If you’re using a coated blade you’ll get instant kydex wear. Nothing against David, I like his work. But it’s something to think about any time you order kydex. You can ask whoever you order from to make the sheath tension the knife at the top, where the guard enters the sheath. That will minimize wear marks on the blade or coating. Though a kydex sheath that squeezes the blade is probably more secure. There are always tradeoffs.
