You really can't go far wrong with some version of a SAK; there are so many kinds that it's hard not to be able to tailor one specific model to each of your gift recipients if given a little thought. However, this year I grabbed a bunch of the 2016 "Kokeshi" Classics as stocking stuffers for female friends and relatives both young and not so young. Like the "Blossoms" model of last year, it was just too pretty to ignore. And for anyone born in the Chinese zodiac year of the monkey (1932, 1944, 1956, 1968, 1980, 1992, 2004 & 2016) the "Three Wise Monkeys" Classic isn't a bad choice either.
For my more "hands on" sort of friends who don't mind getting a little dirt under their fingernails now and then, I set aside some Victorinox EvoGrip 18 models in yellow and with the locking main blade. They're fairly cheap right now (well under 30 bucks) and are built on the smaller 3-1/3" Wenger chassis. For those that despised the Wenger-style can opener, you'll be glad to know that Victorinox ditched that style for their own after the assimilation of Wenger.
