There are knives, and there is the Tool Logic’s SL1 utility knife.
The frame is made from Zytel, which is a light weight yet ultra strong thermoplastic polymer. In short order it can take a licking. But that’s hardly the shining feature of this multipurpose tool.
There is also an LED flashlight that stays in place thanks to a magnetic bass. Remove it and it can easily be stuck to the under hood of a car or any place you need to shine some light, provided of course there is a metal object to stick it too. If need be, it can also help you pick up nuts and bolts or other fiddly metal objects that your banana hands are just too large to pick up. The 50/50 “razor sharp” serrated blade measures 3-inches long and is forged from stainless steel, meaning it should never rust and probably won’t dull very easily. To boot the whole getup is waterproof, even the LED flashlight and includes an emergency whistle.
Surprising you can grab this bad ass knife from Amazon for just $24.
