greetings, a few days ago I happened to come across a piano with particularly hard pins, so much so that it made me reflect on the need to buy a carbon key, which flexes less, and perhaps with a telescopic handle that gives me more leverage. at the end of the work my hand from using the key was aching and I would like to avoid this situation. I am asking for advice from anyone who can give me first-hand information. it is possible that there is already a discussion on the subject on the forum, in which case I would appreciate a tip on how to find it.
thanks anyway
