The Mission Bowie is much harder to come by. You can usually find Sly II's listed on E-Bay or thru private individuals rather frequently, as there are more of these in circulation. Mission bowies, on the other hand, are a little more rare. They do come in an assortment of finishes, just like the SLY II. I have recently acquired versions of both knives, and are they ever nice. Jimmy Lile made some damn nice pieces. Are looking to purchase either one of these knives, or do you have some for sale?
