What are your real world signs it’s time to touch up the chain?

[Alan]

I wanted to start a practical Logging Forum thread on chain sharpness, because I think a lot of us have had that moment where the chain is “technically sharp,” but it still cuts like trash.

What are your go to field signs that tell you the chain needs attention, even if it looks fine at a glance? Are you watching chip shape, how much you have to push, how the saw pulls, heat, dust instead of chips, or something else?

Also, what filing angles do you actually stick to for hardwood versus softwood? I see a lot of advice online, but I’m more interested in what people consistently use in real work, and why.

Bonus question: how often do you touch up in the field before you decide it’s time for a full sharpen or chain swap?

My biggest sign is chips turning into dust and the saw starting to feel like it needs you to push instead of pulling itself. I also watch if it starts cutting crooked even when my bar and rails look ok. In the cold January air, a dull chain feels extra annoying because everything just slows down.

It's just not cutting the way it should , as in as quickly as normal. I'll sharpen it, if it's still not cutting like it should , the rakers probably need to be filed down. It amazes me how little attention some people pay to their rakers.

Chains are cheap, if it's getting worn out, just change it. I buy chains 100 at a time, they are disposable, think of them as washer fluid in your truck. Use plenty , they're cheap.

If I’m leaning on the saw or it’s making fine powder, I treat that as a safety flag more than a “performance” thing. Dull chain makes me rush and that’s when I do dumb stuff. Quick touch ups more often feels safer than waiting until it’s bad.
