At a minimum, they would have to be very good, and very fast with large knives. I use the Klingon management style when in the kitchen. ;)

Actually, nobody gets in my way when I brandish sharp things. I specialized in esoteric Chinese weapons for two years back in the day (giggle). I demolished ceiling tiles, glass fixtures, outdoor shed roofs (rooves?) while in training. Mr. Sg is so great in the kitchen that I try not to endanger him or any other member of the household.
Have fun tomorrow!
