The Chain Sharp CS-X from Pferd sharpens your chain and rakers at the same time. When you want to switch from sharpening left teeth to right you simply flip the CS-X over. The Chain Sharp's design ensures you get the correct angles every time. Chain saw sharpeners from PFERD are exceptionally well suited to the manual sharpening of saw chains. Manual sharpening is more economic and much more gentle than machine-based sharpening, and can prolong the service life of the saw chain. The CHAIN SHARP CS-X chain saw sharpener stands out due to its excellent file position, ergonomic shape and easier operation.
