For the Knife of Me - New utility knife from Irwin
Why a Snap Blade?
The Irwin Bi-Metal Snap blade actually contains 8 mini-blades. When you notice that your blade is starting to lose its edge (i.e. it's as dull as a fish's abdomen) you simply extend the blade, snap off the old segment along a scored line and voila - fresh new cutting surface.
The Irwin snap knife is ergonomically designed and easy to control. It has a handy storage hatch for up to 3 replacement blade, and the blades themselves are composed of two different kinds of metal to maximize efficiency and durability.
The body of the blade is spring steel, so you can exert a lot of pressure without breaking the blade and launching bits of shrapnel into soft body parts. Tough, hIgh-speed steel forms the blade edge, keeping the edge sharp much longer. You'll get 3 times the number of cuts you'd get with a regular carbon steel blade.
Irwin also makes a Pro model that has a slightly stickier grip, contains free refills, and comes in two sizes to fit your very own hand. Available at most hardware retailers.
