Looking at them again, am I right in thinking it's the Old Timer stockman that's seen the most use?
That's probably true because at one time, that OT and the little kabar next to it in the pic below were my only whittlers. I've had both knives since the early 70s.
I don't use the Old Timer for whittling as much as I used to. Believe it or not, I prefer an SAK for most whittling I do with a pocket knife, although I still like the tiny, thin blades on small folders like that kabar for getting into tight places. But the large handles and thin blades on SAKs make great whittlers. If the steel is bad for whittling, it's news to me.
The Schrade with the copper inlay is also an old one and has been abused quite a bit. The scales were broken and the clip blade is still slightly bent. This knife was a toolbox knife for many years. I had the scales replaced obviously.
The large two-bladed Schrade folder has cleaned a lot of fish and field dressed and butchered a fair share of deer. It dates back to the late 60s. Folders like that have thin blades and large, wide flat grinds, making them great slicers and perfect for outdoor use imo. They were pretty common among outdoors folks at one time. However, the Buck 110 was sexier and generally replaced them. A friend of mine with a similar knife got a little careless with one and it closed on him while he was cleaning a deer. Got a big cut in his hand and ended up in the emergency room.
The thing about slip joints is that you can't be careless with them but generally I don't think they are any more dangerous than any other knife. However, I do like a good lockback.
