Set #1 Simple Crimps offer about 1/4" inch of room to dig into. More specifically, the range is 10 to 14 millimeters deep crimps. This set is the smallest in our line as of 2025 and is the most difficult set in this series.
You are crimping down on the plate's "crease." Each hold varies in depth and width, which is a nice variety in this set. Most have a positive incut, but a few are flat to barely incut, and one is slopey.
If you set these on vertical walls, you can get gym-grade V3 out of them, especially with bad feet.
