Trifacet blade for stab incisions, initial groove and tunneling. Titanium handle with locking mechanism. Extreme sharpness of the blades. Minimal pressure. Up to 3000 incisions. Natural diamond. Predictable cuts and architecture of the wound for more consistent healing. Potentially reduced risk of wound leak. The cutting edge of 4-10 nm pushes the molecules apart without damaging them and allows the penetration with minimal pressure.
