Disregarding the difference between a straight and a shavette, as I have been given a shavette I have tried to use it. I found it didn't cut that well, using a yellow 7oclock. Changed to a half astra platinum and it seems better but not a patch on the same blade in my de. I gave up this morning when I scratched myself and just finished off with the de. I'm not sure whether it's worth persevering
