Sandro, I also have a pair of duel cutter/strippers like Electricmanscott has and really like them. They work really great on 12 and 14 but have their limits. Don't try and slip in a #10 or larger, it will take the life out of your tool. If used within it's design you will enjoy using them. But if you don't fancy two or three tools in your pocket vs another trip to the truck for a pair of lineman pilers or dikes they'll be a great addition to your tool bag.
