C228 Sliverax

"Designed by automotive engineer and knife enthusiast Paul Alexander, the Sliverax is the first factory-made folding knife to combine Spyderco’s Compression Lock™ mechanism with a flipper-style opener. Its sleek drop-point blade is crafted from CPM® S30V® stainless steel and proudly includes both a fully accessible Trademark Round Hole™ and an index-finger flipper to support a full spectrum of one-handed opening options with either hand. A full-flat grind gives it outstanding edge geometry and its slightly negative blade-to-handle angle enhances its cutting leverage and shortens its opening arc for swift, positive deployment.

The Sliverax’s blade is supported by Spyderco’s patented Compression Lock mechanism—a high-strength lock located in the spine of the handle to greatly reduce the risk of unintentional release during use. Its lightweight, open-backed handle design features stunning carbon fiber/G-10 laminate scales and nested stainless steel liners. This advanced construction style provides impressive structural strength, keeps the knife slim and pocket friendly, and offers a solid foundation for the knife’s lock mechanism. To allow convenient carry and keep the Sliverax instantly accessible, its handle includes a reversible deep-pocket wire clip that can be configured for right or left-side tip-up carry."
