This past July, I purchased the Solo knife from the SFO. This is a gentleman's knife.
The blade is a sleek four fingers long with an unbelievably sharp edge. Instead of the Spyder hole, there's a giz on the back end of the blade that helps you open the knife as quickly as any Spderco tool.
However, with its elegant design, it doesn't come off looking like a frightening looking weapon.
I carry the Solo all the time in any situation, except while flying. This is a reasonably sized knife that passes muster in a business setting. I also generally carry my Military (except in a business meeting).
Check out this knife if you get a chance.
One way or the other, you pay for your tools!
