How PowerSharp Works
- Steel pins in the bar-mount sharpener slide through the twin guide holes in the PowerSharp bar, ensuring perfect alignment between cutter and the crescent-shaped sharpening stone.
- As the chain moves through the bar-mount sharpener, the unique top-sharpening cutters contact the stone, which hones them to knife-edge sharpness.
- The guidance drive link works together with the cutter and depth gauge to provide the stability required to create a precision cutting edge.
- The diamond-coated dresser link resurfaces the stone, ensuring flat cutter to stone contact.
This bar uses 50 drive links of 3/8" low profile PowerSharp chain - ORF PS50
