This chain needs sharpened. I use a Granberg jig to do it myself, but this season (my second with this jig) I was really disappointed in the results because it seemed like after 5 minutes of cutting it was like I might as well have not sharpened at all. This is the chain that is on the saw right now and it basically doesn't cut a single thing. I'm 100% sure it's something related to what I'm either doing or not doing while sharpening. I know I've got the angle right, but I think it's the height I have the jig set at that's the problem. There's no curve under the tooth.... the tutorial the jig's directions referenced online says that 1/4 to 1/5 of the file should be above the top of the tooth, which is approximately what I'm doing, but I still don't think it's right. My typical routine is 10 strokes (one direction) per tooth, which seems to be way more than what most people say you should have to do. This chain has not had the rakers done yet either... I have others where I've taken the rakers down but they still don't seem to work as well as I would expect right after doing that, so I'm sure it's something to do with my sharpening technique. This is one chain of several, so how would you go about fixing it and bringing it back to something respectable? Critique away!
