Are you trying to make the picks out of a tape measure? If you are ...why?
Just get some hack saw blades/wiper blades.
I just use a template from the template sticky thread, I then photoshop everything out of it so you can't see anything but the pick, no white except where there are curves.
I then open it in Microsoft Word, and resize it to W: .31'' and L: 4.7''
for example, here is one *not resized*
Then I cut it out, glue it to the hacksaw blade, trace it with a fine tip permanent marker (so it won't go off when you quench it).
