This is a hand rebar bender number B6 built by DC Mach Inc, in Houston, TX.   It is designed to bend up to #6 bar or 3/4".   It has a 40" handle to help with the leverage too.   The head is tilted in such a way as to help your back a little by not having to bend over so far.

It is tested tough in the field from the Virgin Islands to Canada.  You know for a fact if it wasn't a great tool I would hear about it.   These tools are a perfect low dollar bender for general construction roadways or slabs.   I paint these tools black to protect from corrosion and paint the heads red so you can find them on a construction site.
