Spyderco Caly 3.5 Carbon Fiber ZDP-189 Plain Edge Knife
Spiders has several knife designs that remain steadfast year after year.  What keeps people buying them over decades is their basic function but also that they're upgraded or refreshed with new technology and materials when they become available.  A prolific design in Spyderco's line is the Calypso. Its arrival over a decade ago as a mid-sized folder has spawned numerous variations and converted legions of knife buyers to the benefits of flat-ground, thick leaf-shaped blades.  This is a workingman's or woman's folder founded on the premise that a comfortable, usable pocketknife is one that feels like a natural extension of your hand. A larger, newer Bionic version of the original Calypso Jr. is the Caly3.5.  The latest Calypso progeny has a three and a half inch VG-10 leaf-shaped blade that is thick at the tang, then tapering to a tip.  The cutting edge is flat-ground and thin for precision and receptive cutting. Ergonomics and control were taken into the designs' consideration and where handle and blade meet is a substantial finger coil.  This is the spot where the index finger settles ergonomically leading the thumb to naturally position itself directly above on the blade's spine.  Also the spine is textured with slip resistant jumping making the knife feels like part of the hand with no sliding forward or backward while cutting.  The black G-10 handle has a mid-positioned back lock and a low profile wire clip, holding the folder deeply in a pocket facing tip-up.
