Rare earth magnets are far stronger than your ceramic type of the same size.
And what most don’t know is you can quadruple the strength of the RE magnets by simply putting a tiny piece of metal on the other side.
Although it may be too late for your existing bottle openers, for the next ones, bore a countersink hole, glue in a washer (or available cups that they sit in) then the RE magnet and finally your wood cover, you will notice a ten times stronger grip compared to the six that you have now.
