I was flit-zing around the net a few minutes ago trying to increase my saw sharpening knowledge a little when I ran across this.
Hello: David
Hand saws are extremely difficult to sharpen correctly by hand, if not totally impossible. Mitre saws have tiny and closely spaced teeth, making it impossible to sharpen with a hand file.
Attempting to hand sharpen the saw blade with a file will ruin the saw teeth. The only safe and accurate method is to have a professional sharpener sharpen the saw.
A professional using a saw sharpening machine designed specifically for the purpose ensures to restore the teeth to there original sharpness.
Specifically designed hand saw sharpening machines use the indexing method of advancing the saw blade to each tooth and uses a file to do the sharpening.
Each tooth cuts on the opposite of the other tooth. Which means each tooth is alternate of the other. Therefore, every other tooth gets sharpened in one pass of the sharpening machine, then the saw is reset in the machine and the every other is sharpened.
After both these processes, the set has to be restored. Another machine for this purpose. Set is the outwards bend of the tooth. Another a process that can not be accurately done by hand and without a set tool.
Best bet is to have the saw professionally shaprened. Saw and tool sharpening shops are listed in the phone directories under sharpening services.

I only wish I had seen this BEFORE I bought all those saw files, saw vices and spent all that time learning to hand file and refurbish old saws. This in turn would have saved me the time I wasted making my own joinery saws from scratch, and all those hand formed teeth that have been doing the impossible :)
I'm surprised at the scam that has raged on for over a 100yrs in the sale of tools and hardware to perform an impossible task!
(I hope everyone is seeing the humor and light sarcasm in this post :) )
The bad thing is, there was a time before I started messing with old saws that if I had read this, I would have believed it, and missed out on learning a skill that I find truly rewarding.
