Not much of a fan old folders. But when I use one, its either a Swiss Army Hunter or the Normark Super Swede below.
I've had the Super Swede probably 20 years, and as the scratches on the blade attest, its a working knife not safe queen.
Although not as fashionable as the latest tactical style folders, its strong, bomb proof and takes a shaving edge; in fact the Sandvik steel never fails to impress me..
