At Knob Creek, I asked about the Sus Scrofa -- one of the folks said that they have a friend who does leather work and loves it for cutting patterns. Basically, it's a Wharncliffe/Hawkbill hybrid that is probably ideal for certain specialized tasks. If you cut line or you're an emergency responder who may need to slice through harness belt material, it's probably a great tool. Perhaps if you need to cut hoses or shape gaskets it could be just what you're looking for, but I ended up canceling my order because I couldn't convince myself that I had a need for one.
I have a few ADs and BADs, but no Busse Combat Wardens -- I didn't like their handle. I like the AD style, but if I was currently looking into an EDC, I'd go for the Mud Puppy (I fully intend to buy a few). As far as Busse Combat EDCs, I'd recommend a BAD if you can find one, although you'll spend more than for 3 Mud Puppies. If you want INFI, but don't require that it be a Busse Combat, then I'd search for an SS4 -- they can sometimes be had for about $200. The Street Scrapper 4 is a favorite with just about everybody who's ever held one.
