The Black Diamond G4 utilizes unique, state of the art, 100% USA wear-resistant alloy. With our beautiful “Black Diamond” wear finish fostering a smooth “buttery” glide to the cut, the G4 excels on both natural cane and all synthetic reeds. Exciting features include a newly designed length, a refined radius tip for precision work and a comfortable rounded back scraper for further pinpoint scraping options. With two new, elongated, contoured and curved rail bevels, specially designed to profile rails and re-contour the spine of both single and double reeds, the G4 is a must for every serious reed player! Encased in our ReedGeek self-locking neoprene bag and case, instructions included.
