The Chain Shark

The Chain Shark semi-automatic grinder attachment was developed to help in the chain sharpening process, giving you a razor sharp edge consistently while reducing arm stress. The Chain Shark will work on chains from 1/4" all the way to 3/4" harvester chain and everything in between. Unit mounts easily to a Oregon 620-120 or Tecomec Super Jolly. This is for The Chain Shark unit only.
