The raker controls the depth of the cut, if you aren't taking them down then how well does it cut by the time the chain is almost worn out?

I have no problems. I tried once by eye but I took too much off and made the chain too grabby. I'm sure I'm giving up some performance but I also don't believe that a chain with it's teeth sharpened near to the end of their life will not cut if you leave the rakers alone. I only run Sthil full chisel chains and I'll keep sharpening the chain until I hit the scribe line so it's not like I'm not getting the full life out of the chains. But I also am not in a hurry. I mostly use my Dolmar 7900 so HP isn't an issue. I just let the saw do the work and watch the chips fly out. Every 2nd tank of gas I give the chain a quick touch up (or if it feels like it's cutting slow).

I’d rather have a grabby chain vs one that’s sharp and won’t cut.

That's why they make a raker gauge. I did the same thing, and it took a few sharpenings to bring it back. Yet running a dull saw is too fatiguing to me... and filing the rakers is part of sharpening the chain.

I agree, the rakers have to be filed down as you sharpen the tooth, IF you expect the chain to cut well.

Also depending on tooth you need to remove the gullet as well such as on a square tooth. I normally do them every 4 to 5th grinding as well as the depth gauges self feeding is a must if you’re in a production environment why be tired at the end of the day.

I also profile the front edge of the rakers as they start to get filed flat and start developing a squared off leading "corner" that causes added grabbing. You can take a small flat hand file and radius that front corner down in 10 seconds per rake and allow it to have a sloped front edge instead a hard corner. You'll still have your newly trimmed flat peak, but get rid of that sharp leading corner. It makes me feel better about my chains.... I also use that newfangled thing that does the rakers along with the teeth at one time. I used to hand file the teeth and then use a raker file guid and flat file the rakers in a second pass. Now it is so quick and easy to spend 5 minutes before each day of cutting and "tweak and peak" the chain that it is crazy not to have this new style file system.

I use the Pferd file rather than the Stihl branded one. Man, that is a game changer for simplicity and effectiveness.

You're not the first person in this thread to mention that system, I'll have to check them out. I just started rounding off my rakers as you said... I"m not sure how much difference it makes but it sure looks better.

Always been my view that anyone who takes their loops to someplace to be sharpened has deep pockets anyway so it don't matter how much they grind off a chain because being flush with money. they can afford it... Me, I cannot, why I do my own. In fact, just did 4 loops yesterday and set the rakers too.

One in the same actually. Just different colored handles. (removed) and Stihl are identical, except the price.

The'P' is silent. It's (removed).

I have the Stihl model. The only thing I find wrong with the tool is the grip. It just isn't very comfortable to use. Maybe it's just me. However, the concept is great. It does a good job of keeping my chains sharp enough for the hardest wood I've cut: pacific madrone.
