that wokshop site is cool, so tempted to get something like this. cheap, thin and flippable.
The Wok Shop's carbon steel hand hammered 'pow' wok
i imagine care would be just like the carbon steel de buyer skillet i use, i just rinse/scrub it out with hot water and then reheat to dry it.
if it gets dull looking i'll rub a very light coat of oil in it, heat, then wipe it out again...
i'm tempted to order a wok, so cheap...if i do i'll probably get one of those DEBA knives too and some fancy chopsticks...
