Cut your hammer with precision using a Leber V2 Hammer Eraser cut jig. Manufactured to @S3igu2 spec, simply mark your hammer and begin trimming. Keep the hammer in the guide or remove it, the choice is yours. We recommend you simply use the jig as a guide, but with patience you can have success keeping your hammer in the jig.
