sharpen blades

[Wolfgang Rother]

Hi all. Since i sharpen my blades by myself. I realized that WM sharpen them max. 8 times and they are gone....WM service in Germany. when i do it i can do it like 15 times and more.
How many times did u get out of them??
Or any advice??
I love the new videos from Cook sawmills and the old ones of thomas TC sawmill with his friend Mr. Roberts.
If u know some videos loke this. Pls. let me know.
Greetings Wolfgang

Much depends upon the sawyer and his attention to the blade's sharpness or not.  When the blades are removed are they;  "not sharp' or "dull"?  Not sharp blades only need touching up whereas dull blades will need more of the tooth removed/ground away to get rid of the rounded tooth tips.
