Tools for Concrete Formwork and Rebar

Ideal tie wire reel
The Ideal tie wire reel is the most popular tool of its type, and is made by the Ideal Reel Co. of Paducah, KY. It was invented by George E. Beiderwell, who received US Patent 2683000 on 6 July 1954. His application summarized his invention as follows:

This invention relates to reels for dispensing tie wires and it has for its object to provide an improved type of reel adapted for use by either right or left handed persons and from which short sections of tie wire may be dispensed, for the use of workmen employed in fastening together the elongated steel rods or other shapes used as reinforcing for concrete buildings, bridges or other structures.

Old cast iron and steel form tie wedges
The reusable form tie wedge is another tool for concrete formwork. An early form tie wedge was US Patent 1808912, patented 9 June 1931. The wedges can be cast iron or stamped tempered steel.

An early rebar bender is below. All parts were forged steel, it weighed 200 pounds, and it was bolted to a plank or beam.
