SOG Centi II Black Oxide Blade Lockback Knife

The SOG Centi II has a 2-inch 3Cr13 blade in black oxide, a stainless handle and a lockback, closing to 3 inches.

At 3 inches closed this is a keyring knife rather than a pocket knife, small enough to hang alongside keys without adding noticeable bulk to a pocket. 3Cr13 is a soft stainless chosen for corrosion resistance and easy sharpening rather than edge retention, which suits a knife that will spend its life clipped to keys and used occasionally. A lockback on a knife this small is worth having, since it holds the blade solidly rather than relying on friction, and the all-stainless build resists the moisture a keyring knife inevitably meets.

Black oxide grows out of the steel surface rather than sitting on top as a paint layer, so it cuts glare and slows rust without adding thickness that could chip away. Explore more Lockback Knives.
