Wooden or rubber mallets are not suitable for metal stamping work. I even used a Stone hammer to get more pressure when stamping.

Please try to make backup seed phrases with washer material. At the same time, try using a wooden mallet to find out whether it suits the washer stamping process.

Wooden hammers are suitable for woodcarving jobs like mine, they don't require too much pressure and don't produce loud noises.
It muffles the sound a bit.

But about the stone hammer, I just found out, that the material is indeed made of stone.
How does it compare with iron hammers that are both used for the washer stamping process?

Stone Iron Wood

Regarding which one is good and which one produces the least sound so as not to interfere with hearing, it is the choice of each.
The noise level of a person's ears is also different, but the ultimate goal is to choose the best washer material so that it will be more durable and use stamping washers and supporting tools that are comfortable to use in the process.
