It all stems from the old days.

 

a 3/8th chain was a 3/8th chain. and use a 7/32 file. job done.

 

Modern technology means there are numerous pitches of chains (0.325, 3/8, 0.404) that now have different sized teeth. it means a 3/8 chain by one manufacturer may always be filed differently to another 3/8th chain.

there are differences even in-house! oregon 35lg is a 0.325 chain, files with a 5/23 file.

oregon 22lp is a 0.325 chain, files with a 3/16 file.

Give it a few years and it'll be me wrongly telling the young guns they should be useing 5.2 when I fail to keep up.:001_rolleyes:
