Since ingame% and irl% have very different drill charging mechanics, would it be acceptable to use a corded drill for irl% attempts in order to keep consistency over the course of a run? Also, since as far as I can tell the sharpener doesn't dull in ingame%, are there any specific rules for sharpeners (number of alternate sharpeners allowed, switching off a sharpener before it has broken, mounting the sharpener in something to make it easier to hold, etc.)? Thanks.

I mean, nothing says we can't, riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiight?

well any electric drill is allowed and any non mechanical, non crank sharpener is allowed.
Also mounting the sharperner is now not allowed but technically was before

can I modify my drill to spin faster

you could do but you may burn out the motor.
