Cardsharp4 new metal knife: CNC machined from a wafer thin strip of ultralight aluminum including hard anodized surface finish. Cardsharp4 has ultimate robustness and strength. New construction with two-stage, child-proof Zytel® safety lock helps prevent accidental opening and gives the knife excellent rigidity in both open and closed positions. The new improved Zytel® rivet secures the blade to the body. Spring-loaded Nitinol hinges ensure the Cardsharp4 remains flat while in card mode with no sagging. A tough, heavy duty tool suitable for most types of cutting tasks.
Just three ingenious folding operations turn the card into an elegant pocket utility tool. Less bulky than a pocket knife and as sharp as a scalpel. Cardsharp® is the first real innovation in penknives since the first folding knife, which has been around for over 2000 years and is virtually unchanged from today's Swiss Army™ penknife. Cardsharp® is thinner, lighter and due to its use of 420 series surgical stainless steel: sharper. Sharp enough in fact, that it can cut through an automobile safety belt in an emergency.
Cardsharp® was originally designed as a lightweight surgical knife that can be easily transported and safely disposed of by hospitals and medical centers together with paramedics and aid workers throughout the world (without needing expensive and wasteful sharps containers).
Cardsharp's unique surgical blade technology features an extra long 65mm cutting edge that ensures longer lasting sharpness (conventional utility knife blade edge is only 25mm long).
A good test for Cardsharp® is to carefully cut through a tennis ball or two inch foam which is more difficult using a normal carton knife.
Cardsharp4 weighs only 24 grams (regular Stanley® type utility knife weighs around 150 grams, Leatherman® same sized blade knife weighs around 85 grams). Less weight equals carrying and storing convenience plus reduced carbon footprint.
Cardsharp® is a great chef's knife. The blade is sharp – rated 'very good' by CATRA – long and thin enough to cut bread and also extremely useful for fast cutting of ultra thin slices of vegetables including tomatoes, cucumber, garlic etc. Great for camping and expedition use; Cardsharp® is an essential outdoor companion/survival tool.
