How to Sharpen Jointer Knives In Place 

Thanks for this, I bought one of these (UK) many years ago, it had no instructions with it and I never really knew how to use it until now. Have to give it another go. I have a Startrite 10x6 thicknesser/planer and hate changing blades.

Thanks very much, great help:) I bought the Axminster Tools UK version of this tool. An excellent way to always have razor sharp blades. I expect you knew but didn't mention, for reasons of video brevity, lock the head. Also always a wise move, slip on a pair of cut resistant safety gloves when doing this type of job but remember to take off when using any machine.

Thanks for the info going to give it a try as hate taking them out and sending off for sharpening .

Thanks alot for sharing.. I could make this sharpening jig at my shop.

Isn't the center of the blade getting twice as much sharpening as the outer edges? This might not make a difference the first or second time, but gradually as you sharpen more I think the blade would get shorter in the middle region. Still, I think it is great that people are willing to test gear and share their results. Thank you!

It would a lot easier and faster to do all the sharpening operations per blade, thus one complete rotation vs four.... :) Oh, and like Jim said, lock the head... and maybe better just to go in one direction, instead of back and forth.....

Where did you get those sharpeners from sir. I like that very much, ind fact, I have never seen no one showe that type of sharpening joinerblades. Regards, Júlíus

this process should also work on planer knives right?

How do you know which side is 300 and which side is 600? I have that sharpener and it's not labeled. Both sides feel and look identical.

Why rotate every time, and not just go through each blade entirely?

Nice idea but as you were going back and forth the tool was moving a lot so there is no way it worked well way to unsteady of a method in my opinion

Were could I buy one of these
