I didn't do the poll, but if I think about it, I go totally for the classic. Its widely available in most big box stores, inexpensive, and easy to give away. The give away is something I've done with the classic for the 20 plus years I carried one before the executive hit me. I don't know how many times I'd see someone having a hard time using a pen or car key trying to open a package or something. I'd hand them a classic and they were always amazed at how easy it was to cut open the whatever than trying to punch through it with a Bic pen or key. I'd give them the knife and then have them give me a coin. Any old coin will do, old superstition.
I've always said that the classic is the Giddeons Bible of knives in general, and SAK's in particular. A gateway SAK.
