K-Nackers Are Fantastic

By: on 4 February 2026
K-nackers are fantastic. They are large with a very grippy texture. There is a juggy void and lots of variety with the contours. It can be rotated to provide lots of options of varying difficulty on most wall angles. I have two K-nackers. Both are on the 35 degree wall and I mostly use them as pinches and jugs when I’d like to go for one last big hold before I can’t hold on any longer. It could probably go on the ceiling for some people, but not me just yet. I highly recommend.
