A year or so ago when I was just getting into woodworking I bought my unisaw from a contractor that was retiring. He gave me a box of about 10 blades with it and at the time I didn’t think anything of it since they all looked very used and beat up. Well this morning I decided to pull them out and see if there was anything good in there.

I found a Freud LM74R010 30 Tooth Glue Line Rip, Freud D1080X 80-tooth ATB Finish blade, Ridgid R1090c 90T Ultimate Polished Finish, and a Freud D1060X 60 Tooth ATB Fine Finish. These strike me as being worth sending out to get resharpened, but I wanted to double check before I spent any money on them.

There is a guy about 5 miles from me in the industrial part of my town that says he does blade sharpening. So my questions are, first is there some method for determining if a blade is worth resharpening, and second should I take them to my local guy or send them off to someone else that’s specifically in the business of sharpening woodworking blades?

If a blade is bent, I assume I’d see vibration on the saw?

Being the trusting sort, I’d probably haul the lot of them down to the guy and ask him his opinion. If it looks like he’s been in business for a while, he probably knows what he’s doing and wil give you a straight answer.

I ran a small sharpening shop for 10+ years and many of my customers felt the blades I sharpened were sharper than those they sent off to the “big boys” who were using CNC equipment, etc. It really depends on who this guy is. I’ve seen some that don’t have the riight machines or take the necessary time but if he has been around for a while and has a good customer base you will probably be okay. Whether to sharpen or not—look at replacement cost vs. sharpening cost. As was said before look at how much carbide is left. Those blades sound to me to be worth sharpening. Check them first, they could just be dirty and have lots of pitch on them. I recommend Super-Clean, available most auto parts stores, Wally-World, etc. The ingredient that cleans the blade is LYE. If you have any questions that I could help you with just holler.
