Yea, these are indeed at Home Depot (but not Lowe's). But they are about $22 EACH. So after spending $44 (plus tax), I'm still left with nothing for 14/3. They make a 1/4 twist strip tool that works on 14/3 and 12/3, but it was way more expensive.
The other similar tool that was strait and worked on both 14/2 and 12/2 was only about $16.
