    Default diamond paste

    I normally use sandpaper on glaas for sharpening my chisels and handplanes.. I recently bought some diamond grit paste from LV no 6 micron which wouild compare I think to a coarse grit in sandpaper. I have tried using a cast TS surface and on a piece of maple. I am not getting the expected results when compared to sandpaper, seeminly not half as fast. Is this normal?

    Hey Al,
    As far as I know #6 micron is still quite fine particle size - lee valley lists it as comparable to hard black arkansas, or a norton #4000 water stone. Those would be intermediate/fine stones, and not for coarse metal removal.
    I have a norton SiC stone, (coarse and fine) for my basic edge shaping, moving up to a 1000 water stone, and I finish at 4000. Able to shave with the edge at 4000. If I need the edge "sticky sharp" I will use green compound.


    Hope this helps.

    The stuff LEe Valley sells (packaged by DMT) is quite fine. Really for finish stropping or putting the last little bit on a blade.

    You can buy, from some industrial suppliers, diamond paste in a wide range of grits. I use several "grits" to go from my coarse stone, all the way to polished edge.

    I bought mine from Enco in the USA. Much wider range of grits.

    What do you use as a base for the diamond paste? Steel plate, glass?

    I use it mainly to strop my carving chisels, knives and straight blades so I have the 6 various grits I have on a leather strop glued to a wood backer.

    I have also applied the paste to wood to use as a hone, and also on aluminum and steel.

    I am "old school" and still do my rough shaping on two oil stones

    Enco is a pretty good place to deal with. I do some metal working as a hobby and also maintain my woodworking equipment. I originally bought the diamond paste/grease to lap metal - but started to use it for honing/stropping my knives.

    I have the green, red and brown from Enco. They supplement the much finer grits from LV well. The syringes give you quite a bit and I have had the same ones for 10 years now. You use such a small amount.

    Mail order diamond pastse from Lopacki in the U.S. is another source that is cheaper and has a wider range of grits than LV. $6 for a 5 gram syringe

    http://www.lopacki.com/polishes/

    I haven't ordered from them but if you search 'lopacki' on this forum you should bring up an endorsement of their stuff from Frank D. in Montreal who has ordered from them.

    I think that diamond paste is the least expensive way to get into honing with diamond.

    good luck
