Here is a side view of tooth.@firewoodhuntingman Looks OK from what I can see, maybe clean the gullet out, but need to see inside the tooth like in my pics. Looks like the depth gauges might be down quite a bit. Is it real grabby? Should be about .025" lower than the cutter.
Much better photo!Hope this is a better picture.View attachment 288284
This photo appears to show similar damage on the top plate (especially second tooth / Left side). Excessive 'hook' too. Does not look like the profile that the '2-in-1' sharpening guide would make: did you go deep into the gullet with another file afterwards?Here is a side view of tooth.View attachment 288286
This is the chain i ran into the dirt and sand a Month ago and had my Sthil dealer do a tooth sharping, i am guessing your seeing the top of tooth that was in dirt and sand.Much better photo!
Always hard to judge from a picture, but how does it cut? That is what is important.
Having said that . . . it looks like there is some abrasion on the top plates of the cutters? Could be dirt. But if they are worn down on top, that could push the cutters away from the wood, instead of digging in. I would normally file / grind past that type of damage, but again, it depends on how they cut.

Remember that it is only the top part of the tooth that actually does the cutting: about the thickness of the chips that you are removing. The rest of the gullet only helps to remove the chips. A steeper top plate cutting edge may cut more aggressively, but the gullet does not do any of the cutting.

What pitch chain and what file size is in yourHere is a side view of tooth.View attachment 288286
If you're mindful to not get "too far" down into the gullet & still get the inside of your top plate, a 3/16" file instead of 7/32" on 3/8 chain makes for a pretty aggressive pretty fast chain. Produces sharper inside angles.The next thing I want to try (for speed/play) is a real sharp/aggressive angle.
Look at these pictures file size is 3/16 as Stihl calls for in this their 3/8 Picco chain.What pitch chain and what file size is in your
2 in 1 file set up? It's always hard to judge in pictures, but to me, it looks like too small of a file (for the chain size) and too far down in the tooth producing too much hook. You want a nice even arc or "C" top to bottom. In the first picture it doesn't look like the file even touched the inside of the top plate, leaving it with a dull inside edge. (although I think it's just the angle of the photo) The second picture shows a VERY large hook, produced by filing too far down in the tooth with too small of file. Everything is a compromise. Not picking, trying to help. You're filing yourself & that's more than a lot are willing to do. Kudos to you! It may just be my misinterpretation of the photos. If so, please disregard.

What do these cutting chips tell you?Not sure what you are trying to show in those pictures. Both of those top plate edges look really dull.
File size should be 5/32" / 4.0 mm.

If it's dull then why is it doing a good job of cutting?Definitely Dull!
If i took the time to use brake cleaner to remove the lub from my chain, you would see it's just as nicely sharpen as in your picture brother.This is what sharp looks like brother! Any chain can still cut doesn’t mean it’s sharp! Just sayinView attachment 288446

Again, always hard to tell from photos. But that looks like an old, dry, maybe 'punky' log, where you are never gonna get good chips, so that may not be a good indicator.If it's dull then why is it doing a good job of cutting?
Looks like you were cutting soft pine i was cutting a hard dry log, so what does your chips really tell anyone except your not getting saw dust.Again, always hard to tell from photos.

I prefer chips that look more like this (fresh silver maple):

Ash?

Mixed (spruce, ash, etc., ignore the grass raked up in there)

Read it again: maple, ash, spruce.Looks like you were cutting soft pine i was cutting a hard dry log, so what does your chips really tell anyone except your not getting saw dust.
Do you think from looking at pictures is my sharping of chain doing the job good enough?
My small chips of a hard wood tells me it's doing Ok.
