Safe to say ??? No but it seems that many of the abrasive crossover, Diamond is a pretty effective cutter, so you want to be careful how you use it...

Some are looking to improve the actual sharpness of the edge, which isn't a bad thing per se but over doing it can lead to a harsh edge, myself I am looking to only smooth the feel of the edge when I look at using a paste so I want a specific result.. With Diamonds I like the results off Felt as it "Tempers" the cutting effect.

You have to experiment with your edges to see what works best for you, IMHO it depends on where the edge starts, to how things work out
