I find some basic knife skills to be a huge labor saver. I've had the same decent (ie, not serrated) $25 chef's knife for decades and can plow through basic veg prep in a few minutes. I don't like all the extra gadgets except a peeler. When I factor in setting up and washing some chopping or slicing machine, I'm way faster with just a knife and board. Two things to wash. And the board is also used to hold stuff on its way to the pot, so that cuts down on temp bowls too.
