Hi Kimberly!
I was afraid someone was going to say Dona
They're so expensive! But maybe it's worth it. I haven't had much luck finding any...most of them are quasi-parallel. The only other one I found works on a sort of plier mechanism but tweaked to press parallel. The cost increase is remarkably steep so maybe there isn't much of a price difference between those and the Dona tools. I'll have to check it out!
Thanks!
