What Ed says - the only thing that I would add is that when I am rapping down on the top of the becket breaker, I lift up on the becket breaker with the hand that is holding it just as the hammer is striking it. This prevents the becket breaker from jamming on top of the becket and becoming a pain in the buttendski to remove. I know that it sounds counter intuitive, but it works. I don't have problems marring the plate this way either.

It can leave you with a handful if not many chips and dents in the plate and if the plate needs to maintain its condition you might skip the becket breaker. Also my experience has been that becket breakers work best with some tension in the string. If there is not enough to hold the coil tight on the pin it won't break the becket everytime. Of course the more tension that is on the string the more danger there is of flying piano wire, which is super sharp, so be careful. These becket breakers do wonderful jobs of getting the strings off, and there are some things that make it go better. First off, make sure that the inside edge of the hole is sharp. This is easily done by touching the bottom to a grinding wheel. Second, make sure that the tool is held at a slight angle, so that the edge is resting on just the becket, not the entire top of the coil. Third, it doesn't take a mallet slamming down to break the string, just a very fast, sharp, rap. I use a little ballpeen hammer and rarely does the becket survive long enough to drive the pin into the block. I only want the tool to move .035" or so, as that is all it takes to break the wire. I do lower the tension slightly but the coils need to be tight on the pin to make for a clean break. I then use a 1/2" drill to remove the pins from amid the coils, afterwhich the strings are easily removed.
