There are a number in my "collection" I once used a lot and am still very fond of, but "top 3 SAKS" means to me is what gets used the most. These days, and for some time, those have been OH Trekker and Rambler, with Swisschamp a distant third. Actually, the OHT is my main outdoors multitool for yardwork or the boonies, while the Rambler is an auxiliary for the Leathermen I usually carry. The Swisschamp, for its versatility, gets packed when I am on the road, but I haven't carried it regularly for years. Formerly, that was the only SAK I owned for quite a few years, but then my lifestyle changed.
