I have about 30 Podgers in the shop.
They taper from 3/8" to 1" over 18" of length.
The have a large easy to use T handle welded to the top which works better than anything else that I have used.
The T handle is also the standard design in England.
They work perfectly for 3/4"-1" Peg Holes.
Good luck with the extension sockets LOL!
