I have a Spyderco folder, too. They make good stuff.

Yep, Spyderco is my favorite folding knife maker. Quality materials and construction. The Harpy is my favorite design. Very useful but also useful for self defense.
I also have an old Swiss army knife, a Gerber Flik multi tool, Cold Steel Gunsite, Kabar black fighting knife, SOG seal team elite, tactical tomahawk, and my collection of throwing knives which see heavy use.
