Universal G4 Reed Tool. The ReedGeek Universal G4 pays for itself in a few different ways. First, there is the simple mathematical calculation you can make by increasing the number of reeds per box that suit you. Additionally, you can get longer life from your reeds, especially when they warp to a degree that you would ordinarily discard them. This "break even" happens within a few months for most professionals and easily within a year for students. More importantly though, you can get better performance out of any reed with the Universal G4. With its proprietary true edge-retention technology and superior U.S. steel blends, the ReedGeek G4 rivals even the most expensive reed knives sold today, with no sharpening required and no dangerous knife blade. Exciting features new to the G4 include a refined pencil eraser radius ip and a comfortable rounded back scraper which offers further pinpoint scraping options. It offers four crisp planing edges and two new, elongated, contoured and curved rail bevels, which are specially designed to profile rails and re- contour the spine of both single and double reeds. The G4 is finished in a beautiful black diamond wear finish, which provides ultimate refinement of the cut on both natural cane and synthetic reeds. The tip of the tool features a gentle proprietary radius that can be used for precision scraping, including balancing the tip, adjusting the heart or other fine adjustments. The radius allows single-point contact for scraping very precise areas of the reed quickly. On each side of the scraper blade, there is a blade designed specifically to adjust or modify the rails of the reed. These blades quickly define the desired rail profile.
