I have them and love them for trimming up tiny squares made from left-over triangles. The first cut kind of sticks them to the board and makes the other cuts quicker. Retired -- have more time than brains some days. Also like them for going to quilt guild work days -- light and small -- fit into the machine bag that I tote along on public transportation. Worth the money if you get them with a 50% cupon plus 20% off your total purchase at J's. Don't regret the purchase even though I only use at select times.
