C90 Stretch

The C90 Stretch started as a pet-project lockback knife design. Spyderco’s owner and chief designer made it for his personal use, incorporating features he wanted. He wanted high performance blade steel with edge retention super-powers for outdoor cutting: things like wood, rope and anything encountered in the wild. It had to work equally well indoors on cardboard, mail and fingernails. He sized it so it wouldn’t scare non–knife people.

Appearance in catalogs

The C90 Stretch Lightweight first appeared in the 2009 Spyderco Mid-Year Spyderco Catalog Supplement.

Information from the Spyderco catalog on the web

C90BK:

"The Spyderco Stretch has changed over the years much like watching one of your kids grow up. What started as a small basic Hunter model in the 1980s matured/stretched into an elegant high performance drop point folder available in a variety of handle materials and blade steels. The latest is a lightweight model with a black FRN (fiberglass reinforced nylon) handle. The VG-10 modified drop-point blade is ground thin and fully-flat with an arcing belly, installing itself as a winner for outdoor endeavors and carrying everyday. Turned-out with a mid-spine positioned back lock the FRN handle is injection molded and surfaced with Bi-Directional Texturing® When the palm meets the texturing tactile resistance results, stopping in its tracks forward or backward sliding under harsh, wet or slippery cutting circumstances."
