yep that's the 3/8 x 4inch one. Sheath was made by Dwayne Puckett.

I have a leather piggyback rig on order w/ Rainwalker for my M9LE and HCLE.

On that one he's throwing a loop for a 1/2" x 6 firesteel that I got from Going Gear. The thing is a beast and throws off huge sparks that stay lit for 2 or 3 seconds it seems. Although that rig is going to be so heavy it's not going to be very practical. I'm sure I'll end up carrying the CampTramp/Swamp Warded combo much more often
