Thanks guys,
That's what I was worried about, the HR2 looks like the blade height would be pretty close to the 1 3/4" max of the Spec-ops sheath, I know the plastic insert can be heated and formed to the blade, but with the thickness of the HR2, if the blade is right at 1 3/4" +/-, it might be too close.
I do like the variations available from Buy Brown, though kydex will scratch up the finish, mine will be a user anyway.
The thing I like about the Spec-ops style of sheath is the flexibility, both in carrying and mounting, and the pouch on the front is a nice option for carrying a stone, fire steel etc...
I've also considered leather, like the sheaths available from Savage or Patriot Leather but was thinking of going with more of a tactical style for this beauty.
