Ok I hate to derail this fishing thread and talk about chains but ya know...
So I got my chinesium “diamond” chain saw file I ordered to try and sort out my Archer chains

Not impressed but then I didn’t expect to be for less than $5 shipped
The cutting surface is just over half the amount on a Stihl file so you have to take baby strokes
It is also closer to a 13/64" file than a 7/32"

The “diamonds” are pretty coarse but they did cut into the extra hard cutters on the 2 loops of Archer
Total of 5 cutters on 2 chains that just bounce a fresh file right off
Even after filing them sharp with the diamond file I still can’t cut them with a regular saw file
They must have been at the bottom of the pile when they went through the annealing oven or something
This is not something I would be willing to deal with if I was in the field away from a vise and stuffs
I will say it I honestly feel that it cut better and longer after I was able to bring all the cutters to the same profile
I will wear these loops out or lose my temper and toss them out but I certainly won’t buy any more Archer
YMMV
