As of yet, I haven't found a belt cutter/web cutting tool I like as much as the seatbelt cutter on the Victorinox Fireman model (JumpMaster modell too I think). Rounded tip, cuts webbing and seat belts very well, but I am pretty sure it isn't what your looking for.
For my CERT bag, I have a Blackhawk double pouch sheath, one pocket has my Leatherman, the other my SAK Fireman. Works well for me.
