## Description

The MN850 -Safe Zone S-File is a fret file that allows you to quickly and safely round your frets. The file part is U-shaped to fit the radius of the fret, and the top is not diamond-coated, and when both sides of the fret are rounded they glide over the fret without any further sharpening. Premium diamond coating can be cut in both directions of push-pull for fast and accurate filing. When working with precision, the line of the file is placed vertically to prevent the work area from shifting between the actual work area. One side is for narrow/medium frets, the other side is for wide/jumbo frets and works with most guitar and bass. Many repair shops have heard that the existing file wide channels were too flat and difficult to use, and increased roundness for wide/jumbo frets to improve functionality. The ergonomic handle design provides optimal weight and balance for comfort, while the silicone comfort grip reduces hand fatigue. The innovative offset design also keeps your hands away from your body when working. Precautions for Use: Used on stainless fret wire will shorten the life of the file. Please check the frett of the main unit
