Crescent Nicholson T01891 5/32″ x 8″ Round Knurl Cut Chainsaw File – 1 File Per Card

The Crescent Nicholson T01891 5/32″ x 8″ Round Knurl Cut Chainsaw File is a reliable sharpening tool built for anyone maintaining chainsaw chains in the shop, on the jobsite, or out in the bush. This American pattern round knurl-cut file is designed specifically for chainsaw cutter teeth, delivering precise sharpening results on standard 3/8″ low-profile chains, which are common across saws used in forestry, landscaping, and arborist work. With an 8″ length and 5/32″ diameter, this file fits snugly into cutting teeth, giving operators the ability to restore edge sharpness while maintaining proper cutter geometry.

Sharpening with the T01891 is straightforward: position the file at a 20° to 45° angle against the cutter’s beveled surface and work from the inside to the outside of each tooth. This process keeps chains performing safely and efficiently, reducing wear and tear on both the saw and the user. Its knurl-cut surface ensures consistent material removal without clogging, and the steel construction gives the file a long working life even in rough outdoor environments.
