This is a now Discontinued Blue Spyderco Stretch model featuring a flat ground satin finished ZDP-189 steel blade. It is from a private collection in brand new, unused condition with original box.
The Blade: Sal Glesser (Spyderco owner and designer) wanted an all around outdoors knife which could also be used for everyday indoor chores. This led to a flat ground, modified drop point blade, constructed of ZDP-189 steel chosen for its ability to hold an edge.
The Handle: Traditional FRN with bi-directional texturing Spyderco is so well-known for done in a handsome grey-Blue coloring. Inside the handle are skeletonized stainless steel liners for added strength and stability over time.
The handle is also drilled for a four-position clip configuration. This combined with the lock back mechanism makes this knife a true ambidextrous carry. The black coated clip is a nice touch to the Stretch.About ZDP-189: Developed by Hitachi, this steel boasts excellent edge retention. Our research shows many users reporting their knife staying considerably sharper than other knives using D2, 154CM and S30V. Most makers harden ZDP-189 above 60HRC with some going as high as 65-67HRC. The result is a harder blade which will hold an edge longer, but may be more brittle at higher hardness levels. A great steel for repetitive cutting and slicing, but not for prying or an improvised screwdriver. Despite being labeled a stainless steel, we recommend keeping the blade surface clean due to the high carbon content.
