Until the last couple releases (and, of course, excluding the SS4, which was like a startup gift of INFI from Jerry), all of the non-stainless Scrap Yard knives were made of SR77. Dan has also posted that he's been trying to Jerry to release some more INFI for the S5LE, but thus far only the SS4 has been INFI (like a limited release of Bandicoots, the INFIcoots, were Swamp Rat's only INFI knife). The story is that Jerry bought tons of steel at auction when Camillus cutlery went under, and that's where the 154CM stainless came from. Up until recently, like most people, I'd have said that Swamp Rat makes SR101 knives and Scrap Yard makes SR77 knives, but that line is blurring, possible even disappearing. The short answer is that the business models have been changing, and I'm not sure if anyone outside of the Busse production group knows what will happen next.
