The Spin may be the runt in Spyderco's Little Big Knife line of folders but scores points by combining compact size and workhorse attitude. Eric Glesser of Spyderco's engineering department created the Spin to be the smallest possible folder with the largest possible cutting performance and it had to be stylish. Its 1-13/16" (46mm) blade is high-carbon VG-10 stainless steel with a Wharncliffe profile. This shape offers a utilitarian long PlainEdge cutting surface and slightly rounded tip that works well when cutting with detail or even cleaning fingernails. The blade folds into a flat stainless steel acid etched handle that dresses it up while adding textured resistance for top-notch grip.

On the back of the handle is an Integral Lock®. This LinerLock design modification was created by custom knifemaker Chris Reeve, using the handle scale as the lock's liner. With the back portion of the handle doubling as both handle and lock, the need for internal liners is eliminated and the knife can be manufactured incredibly slim yet strong. The Spin comes with a three-screwed stainless clothing clip that positions the knife tip-down in a pocket and also offers a way to money-clip your cash or attach to a necktie.
