Possibly the most popular ‘other’ shape
The Meantone J3 shape is only a hair larger than a real one, and a bit, let’s say, more voluminous than the original.
Obviously that extra volume gives you something more to hold on to (I know I need that), and the Meantone grip bars prevent lateral slippage. Sounds terrible, but basically it means just nice and stable between your fingers.
The business end bevels down to a nicely slim, fairly rounded tip, for your precision and your smooov tone.
