It's a reference only a knifeknut could see. Sal did a good job playing on our knowledge, and doing it in a nice way. It's not a slam, it's cute.
Those Benchmade fanboys who find that kind of reference vexing simply aren't tenacious enough to suck it up and laugh along, too.
How could someone not have said that yet?
+1. Mr. Glesser was having fun, IMHO. The 'inside joke' was between Spyderco, Benchmade and knife knuts. Pretty cool actually.
