This is a good way to store your seed phrase and once you figure out how to use the jig it works pretty good. I would advise having a piece of hardwood or a metal plate for striking your phrase into the washers. The washers fit snugly into the side of the jig where you do not see slots and has a slightly rough finish so it is the uncut side. You will need a hammer and punch set to do this.
