I cut a small oversized square of teabag to go over the split, tiny lick just to make it adhere, then dop nail glue / cyanoacrylate a tiny amount on top to soak through and adhere. let it dry, then you can trim the excess and even file it. If you do a lot of typing it will last until the split grows out
The split is vertical from top to bottom for context.
It’s been trimmed back as far as it can go.
yeah I do that off and on, shits me up the wall.
