There have been a lot of different screwdrivers used in the show and more often than not, their history isn’t very well documented. Dimensions are hard to find, paint is impossible to identify, and all the information is too scattered. This is a repository of all the information we have gathered so far on the various props. Some designs, such as Sonic 11, also document mechanisms to make the screwdriver work. However, it is up the builder to make sure their tolerances allow these features.
