Review on 📏 Relitec Contour Gauge Duplicators - Simple Shape Contour Gauge Duplication - Instant Template For Curved and Odd Shapes - Easy Master Outline Gauge Tool for Cutting Set of 2 (5" and 10" Widen) by Donald Cox

I bought this for my husband and dad for Father's Day. I got my husbands back (didn't think about getting my dads back until it was too late). That's a great idea, but the newer ones have locks. These form well, but you can't track them towards anything because as soon as you try, they'll start moving towards you. Don't waste your time and money, buy with lock or double lock!
