Foundational
I have a 14 year old son that I train with and we’re at equivalent levels on the hang board; thus is the perfect board for beginners & maintenance!!

Excellent product
Glad to have tried out the Whetstone at my gym, then purchase for home. I've been climbing for decades and have some injuries (arthritis included). The rounded more egonomic top is perfect for me and I use this board as my warmup. It's got many useful options and I love that it's low profile. My former hangboard was over twice the size and a heavy material, so mounting it above doors when we've moved several times was always challenging. Not with the Whetstone!

Large radius comfy edges
I randomly tried a Whetstone board at a climbing gym and really liked the large radius edges. So I updated my home hangboard quiver to include one. It's become a favorite simply for the pure comfort of the edges.
