Battery life extender and Klein Beers - were cute too
But I think that the folks at Lee Valley/Veritas really outdid themselves yesterday. Almost every line in the description - from the very fist “perfect marriage of speed and risk” to the last bit about right and left handed versions (snipe hunts in Boy Scouts often had the new scouts searching for a left-handed smoke shifter) had something to chuckle about. As I noted, I particularly like the Thorium bit.
