    I have found repeatedly that my graver is unable to remover broken balance staffs. ( I can MAKE staffs with little difficulty)
    I am using a graver made by E C Muller.
    Is this product of good quality?
    Who is the best maker?

    I haven't used Muller gravers, but I think they have a decent reputation. You can make your own, there are a number of source that discuss making them from tool steel (W1 and O1). I use carbide as I haven't had much luck keeping the edge of the tool intact when trying to cut out a balance with a steel graver. Watch material houses carry the carbide gravers under the names Waller and Widea (sp?).

    I ran into this problem too. The steel gravers were never tough enough,and the carbide gravers chipped too easily. I found this article,and have purchased the cobalt gravers the author suggest. They are much more durable than the steel gravers and don't chip as easily as the carbide ones do.

    I agree with LarFure...a sharp pointed Carbide will chip at the tip if you aren't extremely cautious. On the other hand, nothing else cuts like carbide! I regularly burnish the staff while using tool steel and must rely on carbide to cut through the hardened portion anyway, so carbide is my choice graver. However, a diamond sharpening wheel is mandatory. I'm still searching for a tough, durable carbide product.
