I like the old case 1970-90s knives but not much love for newer ones

I agree with others above that GEC is the best current traditional slip joint. They're made in Pa and appreciate rapidly.

I will admit that other than GEC or the older Case knives, I have several Spyderco knives after turning my nose up to them for years. Good choices of steel and high quality work to satisfy most buyers’ needs
They get carried the most while the others sit in the display cabinet.
