  1. Thanks Sam. This is the first time I've tried to make one of this type with any effort to it so I'm in new unchartered waters for me.

    I got some more time today and cleaned it up, took a bit more off the front of the spine to make the profile suit my eye a bit better, cleaned up the raggedness of the belly, and got rid of the blemishes.

    I cut into the blade to extend the tang, but I don't think I hurt it none, probably would have been blade heavy anyway, soon as i fire up next time ill smooth that area out.

    I tried my hand at grinding the bevels, but wasn't happy with how they were progressing and ended up setting them with a file. I think i might try to do the back end like a kabar if i can get me some leather for the washers, and use some 5160 i got for the hardware.

  2. Here is a new one I'm working on. Source was a nice 1/4" thick file. I ground the teeth off the sides an left them along the spine for grip. You can see where i tried (unsuccessfully) to forge the bevels. I got to try out the new belt grinder on it though and this is what I used to grind the flats. I am looking for critiques and advice on how it looks so far and things I could do to improve, or tips so I don't screw it up. I am also considering increasing tang length.

  3. Hello , I managed to dig this up, hope it helps a bit.

    "DEPTH OF CUT: Using a sweep-9 (a semicircle, radius deep) as the standard, my measurements indicated the various sweeps among same-width gouges (I used 25mm) related as follows:

    Sweep #3 = 5% the depth of a #9
    #4 = 10%
    #5 = 15%
    #6 = 25%
    #7 = 50%
    #8 = 75%
    #9 = 100%
    #10 = 110 to 112%
    #11 = 125%.

    "SAME-ARC GROUPINGS: Maintaining the same arc (different lengths of arc from the same circle) while changing the width of cutters, requires changing the sweep as well.

    Starting off with 20 mm wide examples from various sweeps (i.e., a 9/20; an 8/20; a 7/20 etc.) the sweep changes required to maintain a constant arc were as follows:

    For a 9/20 the progression = 5/3, 6/10, 7/16, 8/19, 9/20, 10/22, 11/22.

    For an 8/20 the progression = 5/5, 6/11, 7/18, 8/20, 9/22, 10/25, 11/25.

    For a 7/20 the progression = 5/8, 6/15, 7/20, 8/26, 9/28, 10/30, 11/32.

    For a 6/20 the progression = 4/5, 5/11, 6/20, 7/32, 8/38, 9/45?

    For a 5/20 the progression = 3/6, 4/8, 5/20, 6/35, 7/45?

    "This information may well be of little practical use, success being more in what is pleasing to the eye as opposed to being mathematically correct.
