I currently carry a Robeson Shuredge (made in Perry NY) 2 blade jack knife (both blades open at the same end) with the main blade a clip blade and the other a pen blade. I purchased the knife new in 1962. It has strawberry jigged bone handles.

Or a Case XX 2 blade equal end pen knife (blades open at opposite ends) with 2 pen blades. This one has stainless steel blades and jigged red bone handles. I've had this knife about 20 years.

I've carried others that I have lost, sadly.

If I have pants on with a pocket, I'll have a pocket knife in my left front pocket.
