yes. not only while you're cutting it, but then you don't end up with half a pill here and half a pill somewhere across the room that the pets will probably find and eat.

the majority of my meds are for arthritis which i have in my hands, so the manual dexterity required to hold the pill, cut it with the knife, *not* cut my fingers off is much more than the manual dexterity required to pop the pill on the little angled doohickey and then whack it with the flat of my hand. big fan of pill cutters, me.
