    Default Salm Rock

    I forgot to mention . I finally got my hands on a Salm Rock Coticule.

    Two things surprised me. Firstly is its ease of use It seems fool proof so far and secondly is the quality of edges it produces, they are shockingly good. These really are special in my opinion.

    Great find, the holy grail for many coti users it seems.

    It is only 2"x4".. I have larger Naguras . It does not seem to self slurry and is a hard stone.

    So far I have been working it in 3 stages from a 1k bevel set. Thick slurry. thin slurry & just water.

    I was expecting just a normal coticule to be honest, finer grits are subjective and everything is dependent on the quality of the bevel set in my mind, but the edges so far have had a Wow effect on me.

    I am planning to add it to my site as a service.
    Cheers

    Congratulations.

    Based on descriptions I’ve read, it seems to be the kind of rock you can’t identify until you actually use one. Folks who oet one in a labelled box say they were skeptical (too many Escher forgeries) until they actually tried it out.

    Can you describe how the edge differs from that provided by a good coti followed by a good finishing stone or paste?

    I thought this was a finisher?

    I have some paddle strop coticules and another smaller razor coti.
    I don't think you could fake one of these because of the size and the lines in the surface. Or maybe you could but you would need a box too?
    I only used these previously with full hollows and the edges were really nice. Sharp and smooth, maybe not in the same sharp categories as jnats but sharp enough.
    As I said the edges on this one makes me say Wow.. The edges are distinctive, not like a jnat nor an Escher. Very sharp smooth.. Never used pastes so I can't comment..
    And yes they are one stop hones after a bevel set although I have yet to try and set a bevel with one. To use this as a finisher after synthetics would confuse things and give worse results imo,maybe.
    It is also super easy to figure out so far.. I don't know if your can go too far with one?

    I do have better and more interesting hones but this one is a shock to me.

    Henk Bos briefly mentions them in his essay on coticules and suggests they can be rated at the equivalent of 15K grit. That would support your findings about the quality of the edges they impart.
