I was messing around in guitar center a few weeks ago and stumbled across something I'd never seen on ibanezes, hemispherical fret ends (they were ibby premiums btw). The only production guitars I've ever seen this on prior to that were some ESP E-IIs. I think it's a great touch that can make guitars feel a lot comfier, just like blind fret slots help mitigate fret end creep. I've been working on my personal guitars and builds to put hemispherical fret ends on them since I like the look and the feel of them so much. I wish more brands would do hemispherical frets, they look great and feel great when they're done well.
