Another great example of the importance of "peer review" when evaluating anything. The reviewer had no idea what he was talking about. My favorite part is using the Nagura slurry on the Norton.

This would be like buying a hybrid car and saying it doesn't run well on diesel.

I believe the Wiki has better information.

I would atleast feel compelled to read reviews from people who know how to hone. Sometimes men have to stand up and say "you know what? If I can't hone it might not be the stone that is at fault"
