Concrete workers use Hickey bars to hand-bend rebar for custom work. DC Mach sells a few different versions, but their Type A three-finger Hickey bars are probably the most versatile — they can handle rebar up to 5/8″, using three hardened studs to grip the rebar while bending. And you can even repair your Hickey in the field, if you have a torch and grinder handy.
DC Mach makes the handles from 3/4″ steel tubing and the heads from 3/8″ plate. Then they press fit and weld hardened, threaded studs into the head. Finally, they paint ’em black with red heads to reduce corrosion and to make ’em easier to locate. The final tool weighs about 3-1/2 to 4 pounds.
Look to pay about $30 for the 24″ Type A Hickey bar, or add a few bucks and get the 30-incher. You can also purchase extra studs, for repairs.
