    Ounce Thickness Inch Thickness Millimeter Thickness

    (2 – 3 oz ) (1/32 – 3/64 in) (.8 – 1.2 mm)

    (3 – 4 oz) (3/64 – 1/16 in) (1.2 – 1.6 mm)

    (4 – 5 oz) (1/16 – 5/64 in) (1.6 – 2.0 mm)

    (5 – 6 oz) (5/64 – 3/32 in) (2.0 – 2.4 mm)

    (6 – 7 oz) (3/32 – 7/64 in) (2.4 – 2.8 mm)

    (7 – 8 oz) (7/64 – 1/8 in) (2.8 – 3.2 mm)

    (8 – 9 oz) (1/8 – 9/64 in) (3.2 – 3.6 mm)

    (9 – 10 oz) (9/64 – 5/32 in) (3.6 – 4.0 mm)

    (10 – 11 oz) (5/32 – 11/64 in) (4.0 – 4.4 mm)

    Was researching this as a result of contemplating a Cricut Maker for it ability to cut 6oz leather. I had no clue as to how thick 6oz leather was/is, and sadly it doesn’t look like 6oz will do (unless the more experienced leather makers here say different).

    Thanks Griff. Very much appreciated. Quite often the thickness measurement is what I key into when all I see, read, or check out talks about the ounces. Nice to have both correlated to one another. Personally am only into knife sheaths and most times prefer 8-9 ounce - think I will start carrying my miniature micrometer with me when I visit a leather store now and pick up those leftover remnants.

    The go too weight is 8 ounce BUT

    Nothing says you can't use two layers of 4 ounce back to back and have a very nice sheath interior. I have also been adding in a layer of Tyvek so there is no moisture transfer and sheath should not stretch

    Yup it's a number of 1/64ths of an inch. So 8 oz = 8/64" = 1/8". I buy 8-9 oz from Tandy. Perfect thickness for sheathes. Although the thickness can vary across larger pieces considerably.

    @John Noon, I need to add more cut resistance to the welt. Got any ideas? I spoke to one guy at the knife show who uses Lexan (GE's name for polycarbonate), but I can't quite figure out how to incorporate that.

    Lexan is nasty when it breaks, if you ever snapped a CD you will know.

    I have used G10 or similar on a rigid sheath and process is similar to leather.
    make template of welt
    cut material to size and shape
    layout stitch holes and drill
    glue to first layer of leather
    make holes using an awl
    glue other side of sheath on
    finish holes and stitch

    You can also use stabilized wood that matches the handle. having the welt extend past leather may be a nice feature but I have not tried that yet.

    I have used Tyvek as a lining in a sheath and it extended up the welt, will be using this on fillet knife sheaths so they can be easily rinsed out.
