It is an interesting question but I think it is good that there is a Swamp Rat.
SR started out a lot like Scrapyard in that they made knives out of cheaper steel than INFI and used RES C handles. After a while though the line developed and they moved a bit upmarket to micarta handles and more exotic designs. They were not as expensive as Busse but they were not the bargain they used to be. In the end it turned out that SR was an exellent middle ground between Busse and Scrapyard.
