Keychain-sized Swiss Army knives from Wenger were by far their best sellers. They are extremely convenient for their small size (65mm / 2 1/2"). The small Wenger knives are flatter and more "pocket-friendly" than the small Victorinox knives. All of these models are now retired, but not yet rare (though supplies are limited). We also have rare, vintage & collectible knives in a separate list, plus a list of all 65mm Wenger knives.
