"We want variety!" It's an often heard sentiment from knife customers and is why Spyderco offers several bestsellers with different handle options. Knife nuts wanting the lightest-weight folders available, gravitate to FRN or fiberglass reinforced nylon handles. Ultra-light FRN is warp resistant, shuns chemicals, and isn't affected by temperature extremes. 

Spyderco's non-locking, one-hand open, clip carry folders are called SLIPITS. Starting in 2004, Spyderco launched a folding knife model called the UK Penknife, targeted for carry in the United Kingdom where newly imposed legal restrictions forbade folding knives with locking blades. As the SLIPIT concept gains momentum Spyderco keeps expanding the line with folders in varying sizes, steels and handles. Newly added are Lightweight SLIPITS. 

Lightweight UK Penknife blades are held open by a notched-joint at the knife's pivot. When closing the blade the notch produces resistance functionally similar to traditional slip-joint penknives. Heightening control and comfort, Spyderco designers added a deep finger choil positioning the index finger on the bottom of the blade directly under the thumb. This lets you choke up near the cutting edge with comfort and dexterity. A tension-wire clip carries the folder deeply in a pocket, tip-up and ambidextrously. 

How is this for variety- the Lightweight Penknife comes with a BD1 Drop Point or Leaf Shaped blade (both hollow-ground) in three edge configuration choices, PlainEdge, SpyderEdge and CombinationEdge™. Also pick your preference of a blue, gray or maroon FRN handle. A UK Lightweight Rescue is also available with a safety-orange FRN handle and fully Spyderedged blade.
