7 dot Canoe,6 dot baby Copperhead, both great walk'n'talk, Canoe especially snappy. Both single springs, and excellent fit. The canoe I can see between the blades,but a piece of standard paper won't fit. Of course it rubs a little opening,but with fitment this tight its unavoidable. I'm not knocking current Case, but the quality of these old ones is astounding. Hard to believe these are a mass produced factory knife.
