    When measuring the blade of a straight where do you start to get the correct blade size? From the top of the spine or somewhere else?

    There are two methods that I am aware of. The one measures from the side of the spine from the point where is would contact a hone when honing to the edge. The other measures from the top of the spine to the edge. If you are measuring to check angles and geometry it is measure from the point of hone contact. I thin the over all measurement is the more recent method and for most us us much more common.

    There are almost as many rules as there were razor makers hehehe

    Obviously the Top of the Spine to the Edge is going to be the most accurate as long as you say that is the way you measured it

    Also some Smiling and Tapered blades change measurements along the blade and they are measured at the largest point

    Some of the Vintage French Razors Muddied the Water for Me in the Beginning Talkin Various Measurement Rules by Makers..Like Say French Grelot Made Razors with 6-5/8th on the Tang..They are Saying its a 6/8th/5/8th..Trust the French..They have a Thick Spine & they Measure 6/8th from the Top of the Spine to the Edge..Grelot Get the 5/8th Measurement from the Bottom of the Spine to the Edge..;)

    Hence the 6-5/8th..:)

    Confused ???..I Sure was for a Moment..:happy102:

    Then there’re the ones the fall right between 5/8 & 6/8.

    And some of those are actually marked

    9/16, 11/16, and 13/16 depending on the company


    They actually marked some of the Boxes/ Coffins that way too

    Had to search for pics hehehe

    My Frederick Reynolds measures more 9/16, but @HolyRollah dubbed it a 5/8. Either way, it is a fine shaver.

    That's a fine, fine looking ODH razor!
    I especially love the cool speckled texture effect on the blade face!

    Does it cost extra to have that cool effect applied to a straight razor?
    I imagine its very time consuming to cover the whole blade that way.
    It really adds 'character'!



    :D

    I think cell rot does add to the “vintage look” ;)

    Used this method to measure my razors. But the real question. When in between, do we round up or down?

    Always round up. Every one knows the bigger blades are more valuable;)

    I do neither if it is not a razor that should have 1/16 sizes I just do a +/-

    like 7/8+
