Information from the Spyderco catalog on the web

C158 Techno:

"Polish knifemaker Marcin Slysz marks his Techno folder with a progressive European appearance.

The Techno falls into Spyderco’s “Little Big Knives” category; meaning it has a smaller blade and handle, paired with a hard-duty locking mechanism, exotic blade steel and vault-like construction found primarily on hard-use, larger knives. Spyderco’s first collaboration with Mr. Slysz, the Techno is also the first main-line production Spyderco CLIPIT to use Carpenter’s Steel CTS-XHP. Knife steel metallurgists refer to CTS-XHP as having the steel properties and hardness of D2 carbon tool steel but with the added advantage of chromium to classify it as a powdered stainless steel.

Ground fully flat, the blade has an oversized Spyderco Round Hole and slide-resistant jimping perched on the spine. The handle is titanium with contrasting blue handle spacers leaving the handle open and exposing the inner workings for ease of cleaning. A Chris Reeve Integral Lock (R.I.L.) incorporates the handle’s back scale as the lock. With the handle’s back side doubling as both handle and lock, the need for internal liners is dispensed with, and the knife can be manufactured lighter and slimmer while retaining greater strength. A deep pocket wire clip can be positioned for left-hand or right –hand use with the blade tip positioned with the tip upward in the pocket."

C158 Techno 2:

"Designed by Polish custom knifemaker Marcin Slysz, the first-generation Techno folding knife packed tremendous strength and utility into an incredibly compact package. The Techno 2 continues this tradition and transcends the original design with even greater functionality and ease of maintenance.

The Techno 2’s stonewash-finished blade is crafted from 3.5mm-thick (0.138 inch) CTS® XHP stainless steel. Its high saber grind maintains a full-thickness spine for strength, while ensuring superior edge geometry for low-friction cutting performance. The refined, near-sheepfoot profile provides enhanced point utility and thoughtful jimping (textured grooves) on the thumb ramp provides an excellent purchase for maximum control during use.

The handle of the Techno 2 is constructed with two solid titanium scales precision machined from 6AL-4V titanium and sporting a handsome stonewashed matte finish. Both feature machined recesses to accept the knife’s deep-pocket wire clip, which is easily reversible to support left or right-side tip-up carry. The reverse-side scale forms the foundation of the knife’s stout Reeve Integral Lock (R.I.L.) mechanism, which locks the blade securely open during use, yet can be easily released with one hand. Green-anodized titanium standoffs join the two handle halves to create an open-backed construction style that reduces overall weight and allows easy cleaning and maintenance. For end users who like to accessorize their knives with lanyards or fobs, the Techno 2’s handle also includes a generously sized lanyard hole."
