Our local national chain sporting goods store (sorry, already dinged for deal spotting!) has them for $28.95 during hunting season (now) and they have the nylon/cordura/fabric sheath. According to the guy behind the counter, most of the guys love the n/c/f sheath as it is easy to clean if you get some blood and guts in it, an it is just about impervious to wear. Makes sense to me, especially if you took the knife camping, etc., fishing, etc., and it was exposed to all manner of the elements and nasty cutting chores. The sheath would need nor more care than the rest of your ballistic gear.
In a hurry to clean up after a cleaning session, I left a small bit of blood and guts on a knife and put it away in a leather sheath. That sheath stunk for a couple of years after that, and I was afraid to eat off that knife after I did that to the sheath. Putting a fabric sheath in the washer with my jeans after I found the culprit would have saved all of that smell.
At the sporting goods store price, I would assume one could pay the $29 bucks, then go to a gun/knife show and get a leather sheath that would really dress it up for another $5 - $10, and still be ahead of the game. Or you could get a genuine Buck leather sheath for the Sunday go to meetin' and wedding days at Amazon for $10.75.
Or as pointed out, go to the local gun shop and pay $66 and get one sheath.
Sounds like it's all good to me. After fighting with the leather sheath to keep it from turning my Browning folder green every time I don't carry it, I would certainly look at the fabric sheath. I grew to hate the leather sheath that came with that Browning, as the brass snaps turned green the grommets turned green, and no matter what I treated with or how I cleaned it, it never stopped. Like the fabric replacement sheath a lot, though.
Added: Just checked "the right store, the right price, XXXXX" and they have now changed the online version to include a leather sheath at the 28.99 price!
