    Default Griffon Rex Tonsor

    When my latest acquisition came in the mail last night, a Griffon 60 carbo magnetic, the more i looked at the grind the more interested I got: I began to suspect it was double hollow ground, or 'double concave king barber' on the old Griffon ads.

    Its 7/8 with minimal wear, doesn't say 'Rex Tonsor' anywhere on it, but naked eye and feel were indicating an almost imperceptable 2nd grind.

    Well, I just looked at it under shop microscope at work with mag turned all the way down, and, lo and behold, with the light angled just right that 2nd hollow jumps out plain as day. It goes to about 1/4 blade width. The transition is so smooth my eyes doubt what i'm seeing unmagnified but its definitely there.

    Now I have an original ad from 1908 that I'm going to frame, and both types of model 60 just like in the ad.

    As we are all a bunch of razor junkies we really like accompanying pictures. Time to send it out for a honing I think.

    I don't believe you.

    You guys are strict - I bet no chewing gum in line too, right. First try uploading a pic, next to a regular Griffon 60 5/8 with a ruler.

    found the simple light test for double hollow posted in 2011 see below. Thanks Utopian, my 7/8 CarboMag is most definitely double hollow ground, though so smoothly joined it is almost impossible to see without shop microscope I think is 10x at lowest.

    You will find that most full hollow razors are ground with two wheels of different diameter. The result is a wider "belly" somewhere between the edge and the spine.

    You can easily test for this if you cannot simply see it. Hold the razor so that it is reflecting an overhead light. Rotate the blade so that the reflection travels from the spine toward the edge. If the blade has a belly, then at some point the reflection will also come from the edge. As the rotation continues, the two reflections will merge near the peak of the belly.
