Here's a rare and highly collectible (but fairly modern) SAK - the 84mm Recruit with fully serrated blade. Victorinox has released several versions of their popular knives with a serrated main blade like the Spartan. There are sometimes a few listed on ebay and if you're lucky, you can own one. I got this as part of a SAK lot I purchased. I almost listed it in ebay without knowing its value! Good thing I like to research before selling or trading anything.
