VIKING WRENCH SET (FLICKR)
|
|
Description: |
| The key features are the matching "rack" type teeth and internal springs forming "one-way" ratchets, and the use of a standard hex shaft for handle, extension, etc. which allows the tool to reach into places difficult of access.
Late 1921 and early 1922 ads show the patent employed in a complete ratchet socket set.
