I have a 1965 Hardware distributor catalog (Baker & Hamilton, of Stiletto
fame) which referred to it as"
Sets Seven in One
8 piece combination tool set in a pilfer proof plastic roll kit. Set
consists of one each of the following:
Point #2 Recessed Blade
Tack Puller
Mechanic 1/4 inch blade
Electrician 3/16" blade
Cabinet 1/8: blad
Scratch Awl Blade
Wood chisel 1/2" cut
Unbreakable (yeah right) amber handle with heavy aluminum chuck

$1.40 / set

So basically they didn't give it a real name.

Similar for a 4-in-1 set, " sure grip plastic handle, aluminum chuck" and a
6 piece hammer set, "Sure-Grip plastic handle, strong chuck"..... Both by
Fuller
