Don't shave my hull with a shaving razor..
Have a Scupper-Pro that gets pretty scratched and niked up from use, launch sites are not all smoothe, shallow water fishing has rock and coral contatc, and oyester beds in unexpected places.
I have cut my self more than once loading/unloading or carrying the kayak from stand to car or roof to water on the jagged little curleys.
I do take a safety razor and shave the curleys off every once in a while just for visual affect, never thought of it helping performance as they go in all directions, and don't notice the differenct but I'm not racing anyone from place to place. No more of unectected cuts do to running your hand or leg across the hull.
I also once stole my daughters flat hair iron, busted it into 2 parts and used the hot flat iron to reshape and flatten out the jaggiies and curleys.. did teh the trick also.. I guess you could use a high enough heat to melt the jaggies and curleys back into the hull but I've never tried it and would be skeptical of getting the roto plastic hull that hot.
