Support BladeForums! Paid memberships don't see ads! I have carried a pocket knife since about 4th grade, 50 some years ago. My first is a little jack that I bought from Sears. That is my letter opener at my desk. After a number of different knives over the years I am liking the Stockman pattern for EDC. Case has an amazing variety of Stockman patterns. I like the rounded ends as a more pocket friendly shape and nicer on the hands. The clip blade where the nail nick is farther out on the blade than the clip break point on the back edge (is that a muskrat blade?) does not look right to me, looks fragile. Case has both clip blade styles (conventional with the nail nick inboard of the clip and muskrat). I bought two Case Stockman knives, one with rounded ends & muskrat clip, and one with squared ends & conventional clip. Then I found a Case with rounded ends & conventional clip. When I received it I was surprised to see that the sheepfoot and spey blades do not share a common spring but each have their own spring on different layers. With all other Stockman knives that I have seen, those two blades are angled so they fit into the same layer and use the same spring. This Case has thinner blades and they are not angled. I am also surprised that the spring strength on these two separate narrower springs seems to be greater than the wider single springs on other Stockman. I guess I am just curious about what is known about those two configurations. Historical background? Is that a Case only configuration? Are there any good or bad aspects of either configuration?
