    Checking TS blade sharpness?

    I was given some 10" carbide blades but know nothing about the history of the blades. I had to spend quite a bit of time to clean the blades with Simple Green.

    By touching the carbide tips, some of the blades appear to be dull compared to a new one of mine. Should I try a test cut to confirm or have them re-sharpened. The blades are:
    2-40T Forrest thin kerf
    1-60T Forrest
    1-60T DML
    1-24T can't read a name.


    Five blades will cost about $10 to ship plus max cost of $16/blade plus return shipping.

    I also have some DeWalt and Craftsman blades, 12T, 36T,40T. Are these worth having sharpened or are just throw-away blades.

      I think the Forrest blades are of course excellent blades and pricey ($95-100) and worth it to have sharpened. Don't know about the others.
      IF you do ship them be very careful, I've seen blades shipped and if there's any wiggle room at all they will start cutting their way out of the cardboard package!

      I'm assuming the forrest blades are the WWII (40T) and their miter blades (60T).

      Craftsman has so many grades it would be hard to tell, they used to call their premium line Excalibur but even then I don't think it compared to the Forrest.

          Thrash. Email me and I'll give you an address of a person that will dispose of them in an enviromentally sound way[8D] I just got 2 blades back from Forrest but have not tried them yet. On was a no-name until I got it back. Now I can see the name Craftsman Industrial on it. By all means get them sharpened, it will be worth it.

              I usually don't sharpen carbide blades until I can see a small piece of two missing from the carbide. Maybe I wait too long but I've never noticed much difference in cutting until they start to look a bit chipped - not on every tooth but on a tooth or two. I don't know if the chips are because I hit something or if they are the result of wear.

              I can't see how you would hurt anything to try them. If they are clean and not chipped, I suspect they will cut fine.
