Spyderco SpyderFly Butterfly Bali Flipper 440C Knife (4.125″ Satin) *Collection*

This Spyderco Spyderfly was recently acquired from a collection. The knife is in great condition with a few light marks from being handled. Pictured is the actual knife for sale.

The SpyderFly infuses traditional Balisong (or Butterfly) knife elements with innovative Spyderco features. Balis are all about swinging, sometimes called doing the dance. Eric Glesser, the designer of the SpyderFly, incorporates Spyderco’s Trademark Round Hole into both handles. The holes position the thumb and fingers (pinching either side of the handle) for superb control while indexing/rotating and enhancing fluidity of the swing. Contours and valleys lining the handle offer friction resistance keeping The Fly firmly in grip while maneuvering. A spring-loaded locking lever attaches to either handle for left- or right-hand use and locks the blade closed (but not open) for safe carry inside a pocket.

Squeezing the handles together releases the lock’s lever. The blade is 440C that is hollow-ground and sharpened on one side only. Straight down the center of the blade, a dagger grind balances out both sides of the knife, again designed for smoother and even swinging. Manipulating the wire pocket clip to either handle or either side of the knife sets it up for a variety of carry options and draw positions. The SpyderFly links all that is utilitarian in a traditional Balisong with innovative features you’ve come to expect from Spyderco.
