Exactly. the teeth actually slant towards the bar so as they are sharpened
the cutting edge is closer to the bar and the depth guages can become higher
than the cutting edge resulting in polish rather than cut. On the other hand
a depth guage too low can be 'grabby' and lead to increased kickback.

I think the part I was talking about are the depth gauges.

As I understand it, you sharpen the teeth and then after awhile you have
to lower the depth gauges or else it still won't cut well.
