Description: |
| From the 1889-05-09 The Iron Age: "Holt Mfg. Company, Cleveland, Ohio, issued a circular describing their Combined Anvil and Vise, the invention of their John P. Holt. It is reported as meeting with a large and satisfactory sale. The vise it so made that it can be separated from the anvil by driving ou the key with a single stroke of the hammer, and can be used as a clamp separate from the anvil. The back jaw has a lip projecting over upon the anvil, so that anything held by the vise can sustain heavy hammering." |
