I am considering sharpening my own: circular saw blades, jointer knives, chisels, planer knives, router bits, drill bits and any other things which require a sharp edge.

Have tried the Harbor Freight circular saw blade sharpener with mixed results; probably could get better with time and practice.

Looking at Foley-Belsaw and Thorvie.

Does anyone have any experience with either, sharpening items like the above?

I’d like something which has some automaticity built into it with easy setup.

Which one or different/other would you recommend and why?

I’m thinking it would be primarily for myself and some friends, and to occasionally get paid for a few sharpening jobs.

Thanks very much.

I sharpen all of the above except tablesaw blades,bandsaw blades and router bits. Going to horrible fraud for tools sound like a waste of time and money.
If your low on money look to the used market.

I have Foley sharpening machines and have been happy with their performance. The only machine I use today is the carbide saw blade machine. Nobody sharpens non-carbide blades anymore. The Foley disc/belt sander gets daily use. After 30 years it still works well. These are American made machines. The HF sander may look the same, but it won’t compare to the one made by Foley. Not sure if Foley is still American made. Sharpening tools requires some experience. It is easy to botch up a sharpening job. A good machine can be a big help, but manual ability is also needed. Todays’ sharpening services use automated computer-controlled machines; hard to compete with. Their machines can duplicate original settings that are hard for an amateur sharpener to do. Without the right machine, the grind angle of a chisel for example will be off from the original bevel. I also have saw tooth setting machines, hand saw filing machine and a few other machines that are gathering dust and rust as I have been out of the sharpening business for 30 years now. Not enough customers to make a living at.

Thanks for the replies.

Can’t find any reviews other than on their website.
Their YouTube videos look great, but I’d like some independent information.

I have been looking at sharpening saw blades and found a video where a guy re-did the HF sharpener.


Also one that was built from a grinder that I am leaning toward doing because the grinding wheels are easier to find.

or this
