The seller says this is a Case 6208. The pattern stamp agrees, says 6208. However it’s not an 08 frame. When I first saw it I thought 06267. The 08 is not a swell center, it’s more a humpback. the 08 pattern is 3-1/4 inches. Swell center patterns are the 67, also 3-1/4 inches. And the 83 which is 3-1/2 inches.
Although the seller shows a picture of the knife next to a ruler and has it positioned to appear 3-1/4 inches long, the ruler doesn’t appear to be measuring from the end of the bolster - looks to me like it’s actually 3-1/2 inches. Which would mean the frame is an 83 pattern. Which has always been a three blade whittler - I’ve never seen a two-blade 83 pattern.
Factory error with 6208 blade in an 83 frame? 06267 with a 6208 blade? Cobbled frankenknife? Or?
