I have successfully resharpened my planer knives about 10 times .
The included magnetic setting tools are there to position the cutting edges precisely.
I have replaced my bearings once and I am about to do it again along with the rollers.
My 733 planer is about 12 years old and still going strong in a production shop.
I get almost no snipe when I use it correctly. What a great tool it has been
God bless all,
Dennis
