That OK tool works great, and you can see it has the wire stripper in the handle.
One end is the unwrap, put it on the post and twist counter clockwise.
Clockwise is the wrap direction.
You strip 1 1/2 inch, shove the wire into the notch on the wrap end, place on post and twist.

Takes a bit of time for these, but I'd try for one recommended by Bill
or one of these:
New OEM Wire Wrap Strip Unwrap Tool Hand Manual Winding Rods For WSU-30M AWG 30<http://www.ebay.com/itm/262798514618>
New OEM Wire Wrap Strip Unwrap Tool Hand Manual Winding Rods For WSU-30M AWG 30 in Business & Industrial, Electrical & Test Equipment, Connectors, Switches & Wire, Wire & Cable, Hookup & Lead Wire | eBay
30 gauge, so if you want to use the stripper, that size wire will be
needed. They used to have
them with semi safe to use strippers for other sizes. If you are really
worried, get NoNics strippers
if you can find them.
