    Easy as pie.  Pick out the biggest one you have and stare at the
angles of the bevels.  Also take note of how there is a ridge running
perpendicular to the flutes.  Keep these images in your minds eye.  Hold
the bit on a sharpening media (I use a small diamond hone) and hone away
whilst preserving the bevel angle and the ridge.  Do the other side.
Schmear with paraffin.  Put it back in the magazine and take out the
next one.  Repeat, until the last one is sharp.  Bob is your uncle.

    I just saw the twist type in the Lee Valley catalog.  Something like
$18 for a set of 8.  If you like that sort of thing.  Me, I'm a proud
luddite who prefers the fluted variety, not some new-aged twisted
nonsense.
