With 1" of incut on these edges, they perform well on vertical through steep terrain. The incuts range from 30 to 45-degrees. To explain 45-degrees, if you put a 45-degree incut hold on a 45-degree wall, the incut is now horizontal to the ground. It becomes a crimp. The incut is smooth yet has some undulation, which gives an organic feel to them.
All five holds make for an excellent set to put on vertical walls for beginners to get the feel of crimping. As you build confidence in them, move them into steeper terrain. The holds will yield V1 on vertical walls and V4 on a 45-degree wall.
