I’ve used this for a year, and it can hold nails, pins, etc., on my wrist rather than in my mouth. Here’s a brief list of tasks I’ve used this for: Putting together a Huffy Green Machine for my son; hanging pictures; shortening pants/dresses. It really does make jobs easier, and I don’t think anything similar exists.
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.
