Dale, Thanks for your constructive input to this thread. I've tried trimming tips with a single edge razor blade. I could never get it perfect.
Is there something wrong with my avatar? Chalking the cue is a whole different subject. The avatar looks like a legitimate one-handed chalking method to me.
But seriously, why do you never get it perfect? If holding/gripping/controlling the
razor blade is your problem, the box cutter frame solves that. In my own case, the
exposed sharp edge is a concern - fear of slicing open a finger is often with me. Box
cutter overcomes that one also.
Single edge blades are about 10x as sharp as utility blades, but you do attack the tip
at a slight angle - if that is a problem you could start the trim at the edge of the ferrule
with a utility knife, then finish up with a razor blade. The key idea is you must whittle
away a little bit at a time when doing a tip by hand and the final step is sanding very
carefully.
One hand...
After several decades around the game in most all of its aspects - I can say without
reservation, one hand chalking is good for one thing, and one thing only, transferring
vast amounts of chalk dust onto your hand, shaft, table bed, clothing, car seats,
carpets, and lawn.
