No mate its apiece of a4 white paper i used as backing it magnified as well. I never used the felt which i think lynn uses with .5 diamond spray. I have in my posession full rang of the new bio diamaond shapening paste and 4 sideded paddle. This stuff cuts fast and can be harsh if you over do it. I realy like the ti rasoir paste and cr.ox. I find a well honed razor with my coticules and i don't need any paste. i've heard good things about diamond spray. This can also be harsh also less is better.
