An Oregon reti (file) is a sharpening tool used for sharpening chainsaw chains and maintaining proper cutting performance. Oregon Tool manufactures high-quality round files, flat files, and filing kits specially designed for Oregon and other chainsaw chains. These files help sharpen the cutter teeth and adjust the depth gauge (raker) so the chainsaw can cut smoothly, quickly, and safely. Oregon files are available in different sizes such as 4.0 mm, 4.8 mm, 5.2 mm, and 5.5 mm depending on the chain pitch and cutter size. Regular sharpening with an Oregon file increases chain life, improves cutting speed, reduces fuel consumption, and prevents extra load on the chainsaw engine. Oregon filing kits usually include a round file, file guide, flat file, and depth gauge tool for proper chain maintenance.
