 Black walnut is particularly nasty on blades. If you get the light just right you can see the silica particles glistening in the wood.

Reminds me of when i was cutting trees down to put in driveway before house was built...   many of the ash trees here (well above ground level) would throw off sparks from the amount of mineral in the bark and really did a number on my chain.

i guess after al these years of getting by with $50 blades, i never saw the sense in thinking about sharpening them, when for a few dollars more i could just get a new one and move on.

You got that right!

I must be missing something. To sharpen a 40 or 60 tooth blade is in the $15 range (at 3B). So even with the less expensive blades it can be a good savings to have them sharpened. Granted if you send them (pay shipping both ways) that doesn't work, but if you have a local who can do it seems to make sense. My blades are the more premium ones, and I send them out in batches to save money. But the come back as good as new. But I do agree, if it works for you that's what counts.

Thanks for the tip.   Looks like Scott joined the New Generation:   https://scottssharpening.com/

Forrest isn't any better than any other high end blade companies. Major companies are all using CNC's to sharpen there blades these days. 

 

My saw sharpener doesn't use a CNC but they cut great. But the other sharper in KC does. I'm sure his work it top notch...

Absolutely! When I had my 12" TS my Amana blades were 100 bucks plus or minus, my local sharpening service was in the same 15 dollar range per blade. My blades lasted years, 10 years even. Granted, I'm not a production shop, but I still used and abused them. Not sure how my bank account would look if I simply replaced each blade when it got too dull to perform. Seems I got them sharpened twice a year on average.

Fred: You might want to see IF Chuck's Sharpening Service down in Piqua, OH could do a few blades.....so far, I've had no complaints when he has sharpened my hand saws...reasonable cost, too..

 

Well I ordered another blade today to replace the blade that was ruined. Went back to a WW II.  i have been installing cabinets all day so I have not had much time to deal with the issue but I did notice something interesting. The trashed blade is a different diameter than other 12' Tenyru blades I have by a slight amount. He ground of the tops of all the teeth down into the steel and actually beveled off the steel behind the teeth. I am wondering if Tenyru blades are slightly larger than 12' since they are metric and his machine ground it down to 12' by mistake. I will check it out later. Right now more cabinet work to do.

12" is 30.48cm (304.8mm).....most metric stuff comes in round numbers of mm, maybe 310mm?

I have had that happen on a flywheel once.  The flywheel was METRIC as were the specs we sent with the flywheel as it was important detail.  That was ignored / didn't matter, or wrong conversion.  Flywheel was way out of spec.  Despite my warning to manager it would be a problem they installed anyway.  Clutch did not work correctly.  I believe they took it out 4 times before someone got the idea I might be right.  

If you are looking for a company that will do a quality effort with your circular blades do not hesitate to give Guinn saw Company a call.  They can sharpen or design a blade to meet all of your needs.  Sharping is ~ $10-$15.  Each blade will be etched with your name and a serial #, and returned in a quality cardboard sheath/package.  I spent approx. hr last year talking and touring their facility.  They run multiple shifts to allow them to meet their customers needs/schedule.   Danl
