Is it ok to round file and then clean up the top plate with a flat file a couple of strokes? I just messed with this a tax but don’t want to get carried away and mess my chains up. The flat file gets the top plate sharp fast
You do not ever touch the top surface of the chain thooth, thats a super thin layer of hardened metal.Is it ok to round file and then clean up the top plate with a flat file a couple of strokes?

Here’s what ur chain should look like after filing , round file onlyYou shouldn’t be using a flat for anything but taking ur rakers down not exactly sure what ur doing
You trying to square file ?I’m not talking about really going at it. Just light touch up
I know a lot of people do. That’s why I was wondering if there is anyone who does a mix of bothYou trying to square file ?
You either round file a chain or square file a chain not mixing both together here is a square file chainI know a lot of people do. That’s why I was wondering if there is anyone who does a mix of
Square filing is more involved of course than round filingYou either round file a chain or square file a chain not mixing both together here is a square file chain
As you progress with square down the tooth you can clean up the gullet as you go like roundSquare filing is more involved of course than round filing

Thank you sir. And everyone that responded.Welcome to A.S.!
Lots of was to sharpen a chain, and you can try ‘hybrid’ methods to see if they work for you (tell us if they do!).
But, starting with fundamentals, each modern chainsaw cutter has 2 cutting edges: one on the top and one on the side. When Joe Cox, the founder of Oregon Chain, invented this chain, about 76 years ago, a key design element was sharpening BOTH the top and side edges with a single pass of a round file. This was revolutionary. For real.
So, if you choose to focus on one of these edges, you need to consider how it affects the other edge. TRIGGER WARNING!!! A lot of guys don’t realize that the 30° ‘top plate angle’ really shapes the side plate cutting bevel. The top plate cutting bevel is shaped by the diameter and height of the round file.
‘Square filing’ (done with special files) shapes these edges differently. Which may be fine if done intentionally, or just to experiment. But taking a conventional flat file to a conventional cutter will likely mess up the side plates, which does the bulk of the work when cross-cutting.

Not only that, but making the top plate thinner will result in it failing earlier.You do not ever touch the top surface of the chain thooth, thats a super thin layer of hardened metal.
You grind that and you have a tooth sharp edge with the hardness like butter.
