My sharpening vries by chain, and what I am cutting.
Stihl chain is the best, and holds an edge better than anything else I have seen.
I sharpend a little less frequently now. I thought I was doing a good job with a basic file and guide. Wrong... I got an Oregon clamp on sharpener. My chains are sharp sharp sharp now. Amazing the difference.
I still touch up a little with just a file, but put it on the jig every other sharpening.
I also carry at least one extra chain, that is sharp.
I found:
- use good bar oil
- use good chain
- use a good sharpening guide; I thought I was doing good before the Granberg style jig...
- Keep the chain out of the dirt, rocks ect
- If you do ding a rock or dirt, swap the chain right away till you can clean/sharpen
- Dont let the chain get dull. Then it usually gets hot too, which affects the temper of the cutting edge. Then it will never hold an edge
- Keep the bar clean, groove maintained, sides filed ect.
- Read the Oregon sharpening and chain care webpage. Great info and resource
