Sometimes a kickstarter project comes along and just makes you say "How the hell do people think of these things?". The SharkTooth was initially one of them for me, but now that I have it in hand it makes total sense. A simple laser cut pendant at first glance, upon closer inspection it is easy to see how useful this tiny tool could be. Besides the ten wrenches cut into the center it is easy to see the saw blade on one edge and knife edge opposite. Harder to see until you hold it is the shape of the point besides being able to sharpen into a spear or arrow point also has a diamond shape which makes it usable as a Phillips head screw driver.
Designed by the minds at Archwing LLC. in Madison, WI as part of what they are calling their Tactical Apparel venture, it really is a marvelous design. They will soon be available for order from this website.
