Dave (Leatherface) is being modest regarding his sheath making skills! I've got 3 Mutt sheaths from him, and the leather models would fit a DMLE wondefully (not the Kydex though - since the Mutt LE is a different profile - but the leather sheaths would do well).
Jeff/Rainwalker is definitely your man for the DMLE though - especially if Dave says so! I'd suggest going w/ one of those two Junk Yard Dogs for all of your Scrapyard Sheathing Needs though - much respect to both of them for their outstanding work - and the fact that they are always here hanging out with the dogs gives them bonus points in my book!
