I'd favour sedate and understated, Sal. Something simple and classy.
The t-shirt idea with a simple 'Spyderco' along with the spydie logo along side it on the left chest (in lieu of a pocket) would be cool. On the back perhaps just a similar small design, up by the nape of the neck.
Going the other way, maybe even a large spyder emblem, but muted...like a light grey logo on a white shirt, or some such. Just thinking out loud now.
Hey, random thought time: how about a Spyderco tie line? You know, nice patterns with subtle images of Enduras and Delicas and spyderwebs and spyders and matriarchs and starmates and such...
More random thoughts: does the spider mascot have a name?
