    do you sharpen your putty knives?

    I have a few putty knives that are the very stiff kind. thick metal, dont bend, that I use for a variety of things, mainly scraping glue off off surfaces before it cures.
    These werent cheap, and they are getting so mucked upwith old glue and dirt.
    besides giving them a cleaning with mineral spirts or other solvent, can I run them lightly over the grinder?
    they all have a beveled edge on them, like a chisel.

    i think i would use a file rather than grinder,, to maintain the temper in the edge allen if you grind them they might get to hot and then wont hold the edge needed to scrape for very long.

    I wait until my Stationary belt sander's belt is about had it....and then run the putty knives through it. The sparks fly, but for cleaning and sharpening, it works well

    Me, too. But I have a belt sharpening system for my lathe tools. I use that. Don't have to wait for a belt to wear out.

    Sander. Or grinder. Whatever. Just don't burn the edge.

    You just have to be careful about putting them in your pocket and such. Some folks don't expect them to be sharp...

    I sand them on what ever I have handy, from hand pad, to belt, or disc....Of course I try to flat sand to get the crud off then whatever edge treatment and I don't usually sharpen them just de nick them. Is that a meaningful description.. "De Nink" meaning to take any nicks out as my putty knifes don't always have an easy life....

    Im going to hop over to Moskowitz's store and pick up some norton stones, and then I need to get up to you for a lesson on sharpening it all the right way.
