Craftsman Kromedge Poly-Tap

[Yadda]

I picked this up in the estate sale items this past weekend.   It is used by electricians to tap or chase threads in electrical cabinets according to what I found on the web.

Good find.  Never saw a Craftsman. 
My electrician brother-in-law always called them triple taps.  His were Kleins.  They had replaceable shafts.
