The 1/3/8/12…20 progression is perfect, you won’t need the 5K.

Surprisingly with modern synthetics you can, in the high grits, make large grit jumps, just fine. The 20k seemed excessive to me. But once I bought one, I too was impressed.

I re-honed a 40+ rotation, once I got the 20 dialed in. Just with the 20K. It is an amazing touch up stone.
Not saying you need one, but doubt you will be putting it up for sale anytime soon…

+1, but we are supposed to reel them in slowly...

Naw, that hook’s deep, reel, baby reel….
