Should be a fun one!
If you are resting the paddle on the blade twist the paddle slightly so that only the leading or trailing edge is touching the blade at any time during the recurve.
Especially at the choil end if the paddle is making full contact front and back… you can see it start to make a groove.
That’s all there is to it. Good luck.!
i normally maintain full contact w/ both corners of the stone the full way through, the key is not to do directly up and down scrubbing motions. instead, you need to do scrubbing motions or sweeping motions covering at least 2x the stone width from heel to tip so you don’t groove anything. works great for me!
