Swoboda4 - I will be posting a blog in December that focuses on knobs and player's numbers on knobs. The blog will not so much focus on players who do, or do not pen their number on the knob, but some interesting ways past and present players have penned their uniform number on the knob of their bats - with photo examples of knobs and pictures of them at the plate batting.....in the meantime, good luck collecting!
