Raised grip rhombuses
The raised grip rhombuses are also inspired by several vintage picks from the 1930s. Then they were fairly crude affairs, it looks like they were pressed or hammered into the celluloid of the pick.
I don’t want to press or hammer my plectra.
So I experimented with raised islands on the cnc. Shape, size and position of the raised islands are all part of the equation. Too close together and your skin will interpret the rhombuses as a single surface, the grip is gone. You’ll only need about .3mm raise, a good distance between them, and preferably sharp edges to each rhombus.
Result? Sticks like glue. Probably better grip than the originals, but I can’t confirm that, since I’ve never laid hands on an original…
Because of their construction, these plectra are very much directional: you play with the tip, and you hold it by the rhombuses. That’s it.
You can’t flip these around for another radius, and this makes the bevel quite important. I beveled these to taper down in the space of about 6mm from the body thickness to a tip thickness of less than 1mm.
All in all a very interesting player.
