Product Description
The Demko AD20.5 in smooth gray titanium is the quieter version of an already purposeful knife. Where the milled titanium carries obvious texture and machining marks, the smooth titanium handle presents a clean, refined surface that feels different in the hand — warmer, more refined, closer to what you might expect from a custom build than a production folder. Titanium is already exceptional handle material — nonferrous, stronger than most steels relative to its weight, completely impervious to corrosion. The smooth finish just lets the material speak for itself without anything added to it. The knife ships in a plastic tube for protection, as Demko does on select titanium variants.
The 2.88-inch Slicer Shark blade is CPM-3V tool steel with a stonewash finish — the same non-stainless powdered tool steel known for outstanding toughness, chip resistance, and edge retention under hard use. The Slicer Shark is a recurved blade profile that maximizes belly and cutting length in a compact overall footprint. Deployment is through a thumb pull that engages the patented Shark-Lock — Andrew Demko's spine-mounted locking system operated by a ramp-like fin. Pull the fin back, the blade deploys, the fin becomes a jimped thumb ramp when open. The whole sequence is fast, ambidextrous, and deliberately designed to keep your fingers out of the blade path at every stage.
At 4.38 inches closed and 4.02 ounces the AD20.5 sits right where a serious EDC should — substantial enough to feel purposeful, light enough to forget it is there. The ball bearing pivot runs smooth throughout. The reversible tip-up pocket clip handles left or right hand carry. A lanyard hole is built into the handle. Knifeworks is an authorized Demko Knives dealer and your purchase is backed by Demko's manufacturer warranty.
