CardSharp  – new improved superlight and supersharp utility knife size of a credit card. Updated features include stiffer, polypropylene body (living hinges guaranteed for life) and unique safety lock (cannot open in pocket or drawer and child proof). Just three ingenious folding operations metamorphosise the card into an elegant pocket utility tool. Slimmer and lighter than an ordinary knife.

The extra long stainless steel surgical blade ensures longer lasting rust free sharpness. The superlight polypropylene body includes a built-in protective sheath that helps prevent injury or blunting. CardSharp2® is an ingenious conversation piece. A sharp idea that slips safely inside your wallet or kit bag.

LIGHTWEIGHT - 13 grams (regular Stanley® type utility knife weighs around 150 grams, Leatherman® same sized blade knife weighs around 85 grams, smallest Victorinox® Swiss Army penknife weighs around 23 grams).

ULTRA THIN - 2.2 mm thick (traditional Stanley® utility knife body thickness is around 25 mm).

RAZOR SHARP - Surgical blade technology with extra long 65mm cutting edge ensures longer lasting sharpness (Stanley® utility knife blade edge is only 25mm long). Blade made from high quality rust free stainless steel. Independent testing laboratory; CATRA awarded Cardsharp penknife; VERY GOOD status for sharpness (ICP mm) and life (TCC mm). Blade color choice: Teflon Black or Natural Brushed Stainless Steel.

SAFETY - Blade edge is protected when stored in wallet, drawer, or kit bag which avoids accidents and blunting (blunting often caused by rubbing against other knives or tools). Integral blade 'sheath' cannot be lost. Protective hilt appears when opened. When docked in closed position, design prevents injury. Cannot fold accidentally (as some folding pocket knives). Blade is locked solidly in open, cutting mode with no blade tremor allowing accurate precision cutting.

WATERPROOF - Machine washable with no hinged parts to rust up like ordinary folding pocket knives.

ECO FRIENDLY - Lightness and flatness reduces storage and shipping costs including carbon footprint. Simple two part construction with automated assembly saves manufacturing waste.

PERMUTABILITY - Highly suitable for customization by pad printing or invisible label (printed 1-4 color lithographic) and/or custom laser engraving blade - please email us if you have a promotion inquiry).

PACKAGING - Various options available including slimline card eco-pack for gift/mail order and harder sell retail design with euro hook.

LEGAL

- Blade is under 3” (76 mm) and is visible when closed so easily identifiable as a knife (optional clear body versions show blade from both sides - P.O.A).
