Oneway Terminte:

The Oneway Termite will allow you to do end grain hollowing faster, deeper, and with more precision than ever before.  As a bonus, it's great for finishing cuts on any flat or curved surface, and because it really is an end grain tool, pommels on spindles can be cut so clean it's unbelievable.

Use the Termite for the finishing cut and drastically reduce the amount of finish sanding.  This will save you both time and money.
