You razor-cut things on this mat, and unlike other materials it won’t accumulate a field of cut marks to misguide your blade. The self-healing rubber keeps the surface uniformly smooth, clean, and firm. And protects your table. Get the largest one you have room for and can afford. A large mat also says: don’t pile stuff here.
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.
