When saving ounces, this is the lightest multi-tool kit to carry. It’s got your knife, pliers, wire cutter, scissors, file, and two screwdrivers in only 2 ounces (57 g). Some folks use it as a keychain fob; I primarily carry it while backpacking and biking. The current best model is PS4.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
