You can reshape the material by standard methods. Sandpaper can be used. We would suggest starting out with 220 and then 400 and then 600 and 1000. The black wet and dry sandpaper works the best, if you use it with a steady stream of water that will keep the paper clean. Be advised that this material is difficult to shape.
We recommend that you not go any thinner than .035″(35 thousandths) or .85mm.
Remember that any modification of the pick will void our 30 day guarantee.
