One of the world’s oldest tools, but one that is often overlooked. This is a heavy-duty needle with its eye at the working end, mounted in a handle. For mending leather, shoes, bags, sewing canvas, or stitching heavy materials, there’s no better tool. I don’t use mine often, but it has a place in the essential toolbox. Your local Ace Hardware sells a kit with tool, extra needles, and waxed thread.
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.
