**If you are looking for a metal or hard as metal tool this is not the right tool for you.  Although very strong and durable, this wrench is made of black Polycarbonate ABS plastic and is intended to replace a discontinued metal tool at a cheaper price.  It is lighter and not as firm or strong as metal.  If you have stuck manabloc nuts or intend to tighten them beyond manufacturer recommendations, then please look for the original metal tool.
