This is a tool that you can use to make guitar picks out of plastic sheets or credit cards. As you can see, it didn’t really worked for me (video below). I suspect it’s something to do with my luck when buying new things.
I’ve seen plenty of videos on YouTube with this exact tool from Pickmaster that worked without problems. For some reason, mine didn’t.
I managed to make some picks by putting the front part of the tool in a bench vise, but the results were not like the ones I’ve seen from other people using the Pickmaster.
Hopefully you will have better luck!
