I think this idea is interesting and would like to try it some day. Some think the rice might damage the edge or dust to get into the pivot but I think there is ways around all problems. You can have the rice and razors separated by something to save the razor from damage (if that risk even exists with careful handling). It doesn't necessarily have to be rice, maybe some other sort of moisture absorbent. Whichever is the best solution I find the thought interesting.
