Saws during the late 50's to the early 70's came with a small tool kit that usually included the following items: flat bladed screwdriver, three round files, one small regular bastard file, a spark plug wrench that was a stamped steel socket with a hole through it- a small round piece of barstock was included; you slipped this through holes in the socket and wrenched with it that way; a small wire brush, extra starter rope, extra spark plug, a hex wrench, and sometimes a small, cheap pair of pliers.
