Hello All,

I made this video a couple of months ago. It seems to get views pretty steadily, so that might mean it is of some use to fellow woodworkers!

I live far from any city, so it is a pain to send knives out to get sharpened or go buy new knives. I found a guy on the internet who made chisel sharpening jigs from a big block of teflon. Using that same idea, I made a larger one out of hard maple to accommodate a 6” jointer knife. Have been using that setup for a few years now, and get good results. Has saved me some time and expense. So here is the video. Maybe it will help some of you!

I am sure that you get those blades extremely sharp using your technique. How long does the edge stay sharp? I would think that the very sharp edge would not last very long before they would require a touchup. However, they might still be sharper than they were after being commercially sharpened.

What is your experience with this?

I probably have to sharpen my blades more often than most guys because I use so much rough-sawn lumber or even small logs (as you can see in the early videos of my Windsor Chair series). You’re inevitably going to get some dirt in your boards that will put dings in the blades.

All I know is that I would get my knives back from the sharpening service, and you could feel the board vibrate under your hand and hear chips snapping off as you passed it over the machine. Completely unacceptable. I doubt if there is a consequence of getting your blades too sharp. I might touch up my blades once or twice a year, depending on how busy i am.

Have your say...
