Extra marks on a chainsaw chain tooth

The marks on the Stihl chain are far to the rear of the tooth and the "end-of-life" has been reached, as well cannot catch a fingernail on the marks so not a problem if reached with a file. One mark on the Stihl chain is plenty to keep the angle aligned, IMO when hand filing.

I use the Stihl progressive depth gauge and it seems to work OK for me.

I was not aware that Stihl made a progressive depth gauge tool. If this is the one you are using, that is not a progressive depth gauge.


I'm not sure if the depth gauge tool included on their "FG 4 Roller Filing Guide" is progressive or not. It appears that it is, but I can't see enough in their picture to determine.

Well, all of these years I've been mistaken . Thanks for pointing this out, although my chains have always cut well.. I will source a progressive tool and assess the difference.
Thanks!

If it helps, use it. 
I myself would not use it.
But if it helps, use it.

Non of you guys is using the 2in1 filing system? since i use it i have not touched a normal handfile again. it's way faster and all the angles are done in one stoke, forget raker height. they perfect after two strokes. (for 95% of chainsaw users)

I bought a 2in1 a number of years ago due to the fact that my hand filing was...well not very good. It works. I did find that you could get the depth gauges too low if aggressive with the tool. I'm now better with hand filing when in the woods but do have an Oregon grinder to get all angles back to spec as mine get off some when hand filing. Also easier to clean up cutter that gets rocked or finds a nail. So, I hardly ever use my 2in1 anymore.
