For what It's worth, I have my BullDog in the Sheath from the yard (listed as a 6 inch sheath I THINK) that I got to house my 6.5. I mailed it off to Rainwalker with the 6.5 so it would not cut throught anything and Jeff checked and said it would fit ok but could stand a slight lengthening of the insert. He I THINK put a 1/4 to 1/2 inch extension on the insert with duck tape as It will only be housing the Bulldog until I figure out what it's new home is gonna be. BUT I personally don't know why it wouldn't work as the regular carry sheath. I mean you could add a short extension made out of any semi-rigid material, and the duct tape is only there to keep it in place.

Oh well, long post out.
