Review on Official Regulation Ice Hockey Pucks For Classic Training And Practice - 6Oz, 3 Inch Thickness, Black by Don Leblanc

I did not buy these for hockey practice. In reality I have very little knowledge of hockey. This review is for those who wish to use a puck as a tuning fork activator. These pucks work very well for that purpose.I am also a jeweler and use a rubber block in my work. I think these pucks would work very well as a jewelers' tool as well. Since there are six pucks, and I only need one as an activator, I have more rubber blocks than I can use in a lifetime.
