I don't use or carry any Full Congress knives anymore, gave them away, although I do have a Rough rider Mini Congress out of interest. The pattern is an old one and very admired but I find it a bit awkward in the hand and they often have blade duplication which I don't care for in knives (same with most Muskrats).
I like the Half Congress, 2 blades, preferably single-spring at each end. GEC have offered them, Queen too and probably CASE.
It's always gratifying to hear of somebody getting interested in Traditionals again and actually using them on the job
Here's a GEC 13 'Clerk' that I've recently become interested in again.
Thanks, Will
