I learn new things about neat 1.14.4 items every day. Today it was the grindstone,
One of the problems of AFK fishing is that you accumulate a lot of enchanted junk. I say junk as being books, rods, and bows which have enchantments you would obviously never want to use or very low level ones that aren't worth building up. Now comes the grindstone....
I use an infinity bow, and never use mending bows so have no use for them except as fuel. By disenchanting 6 of them on the grindstone they are still fuel, but I recovered 3 levels of experience ( from 17 to 20). This is much more than the XP obtained from the AFK fishing to get them. I figure If I empty all my chests of trash stuff I can do better than an average MOB farm.
Yeah, I love the grindstone. Fished for 7 hours last Saturday while I was shopping and watching a football game. Came back and had 4 double chest full of stuff. Threw away all the fish and saddles (multiple chests full of those already) and unenchanted all the bows, poles and books (except for the 2 mending books I got) and got almost as much XP as I did fishing in the first place. Careful when unenchanting bows though... I was just clicking away unenchanting stuff and almost threw my good bow in there...lol. Now I just throw it in a chest before I start so I don't grab it by accident.
