Today Maggie answered me her understanding "the behavior of the pins during rotation", giving the example of the Levitan lever there. I must comment on this there. And, I was forced to create new topic. If we consider the design of the Levitan lever, then this is an example of ergonomics for any tuner.

Since it is very inconvenient for a tuner of a grand piano to work in the sector (15-18) as an ordinary classic hammer. I would call the work here, like "sticking the handle of the hammer into your own belly", then Levitan solves this problem brilliantly, with the help of the counterweight handle he allows you to work here (15-18).
If we do not have Levitan's lever, then we can still use (15-18) to save the wooden pinblock hole. Yes, it's funny and not convenient, but... The breaking of the strings will be minimized, the piano must keep the pitch longer in time. And, most importantly, the piano will serve its owners longer.
Don't throw rocks at Max right away. Try tuning at least one grand piano (15 -18) using a regular hammer and you'll feel the difference, I'm think. Or to press down his madness be using tech.argumently words (15 -18) about
