The Whetstone was designed to be an ideal first hangboard for climbers beginning their training journey. We have included a series of elements that we’ve found consistently valuable for both new and seasoned climbers.

The top jug on the Whetstone is something new. The edge profile was designed to promote a more “active” grip and reduce “over-wrapping” the wrist. A series of “ergo-bumps” was included to both improve the comfort of the grip and also to act as an edge that can be draped in an open-handed grip to more evenly distribute force between each finger as an aid for rehabilitating some finger tweaks.

The 40mm 2-finger pockets are perfectly sculpted to provide the most comfortable pockets you’ve ever felt on a hangboard.

We built in a progression of larger edges for beginning hangboarders (and for experienced hangboarders with larger hands), while still progressing down to a 20mm edge, which has become the de facto edge size for benchmark testing.

The center edge is 40mm deep, but with a fully custom edge profile that is incut at 10 degrees to help facilitate an introduction to more advanced 1-arm hanging progressions
