It's a knife, flashlight, fire starter and signal whistle all in one. Tool logic is better known for those credit card tool kits you see in the "Men's Gift" section at department stores. The only problem is they are never really the size of a credit card nor do they strike me as being very functional.
The SLP2 however, with its knife, light, whistle, fire starter combo seems to have all the things you might need. Especially, if you find yourself needing to find your way in the dark, dry your wet clothes by a fire, or cut something. It also has a whistle so you can signal your buddies when they come looking for your sorry hide. Available from Amazon.com and other retailers for around $30.
