I happened upon these while on vacation in a hardware store (yes, I go to hardware stores while on vacation). These safety glasses provide great eye protection and the bifocal lens allows me to perform closeup tasks without resorting to pulling them off for my reading glasses. Essentially a perfect solution for those who work in a shop with ‘older’ active eyes.
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.
