Scrapper 5 LE specifically. I have Busses and Rats and love them, but the SY S5 LE has something no other knife in my collection has: ResC + Infi. I always switch from Busse (AD or BA3) to Swamprat Howler when the weather gets cold, because I can feel exposed metal tangs even through gloves/mittens when the temps get below 0F. I carry a 4-5" fixed blade in my pack as a camp/survival knife whenever I'm out in the winter (and we are out a lot) - no complaints about the Howler - GREAT little knife, but I've always wanted the Infi+ResC combination in a 4-5" blade. I didn't have the funds when the S5s were offered, but did recently and one came up on BFE for a reasonable price. Now it is mine! Now need a better fitting sheath for it...
