I've owned this Case XX 6375 CV with amber bone scales since it was new in the early 1990s. Recently I discovered it in a tool bag in the garage. It had a significant amount of rust/putting, the blades didn't snap, and the Case shield was lost! With some steel wool TLC, lubing, and cleaning, it's back in good shape with nice "walk and talk" of all three blades. I have a replacement shield en route from Case customer service, which I'll use to make it appear whole again. Until then, I've been carrying it my shirt pocket for a couple of weeks and using it. It's a good cutting tool!
Nice , and useful again.
