|This is my new digital caliper micrometer for better assessing razor-head-|
design aspects to better understand razors' shaving characteristics.
|An example razor-head close-photo. Points A-B determine the blade gap,|
but it's difficult to determine the exact location of point B.
In other words, measuring a blade gap or reveal is not the same as measuring the outside diameter of a rod or the inside diameter of a pipe, where one can snug the caliper blades tight against the dimension-defining surfaces. The razor measurements are much more subjective as to where the start or end points of the measurement actually lie. So these measurements should be considered estimates, not precise dimensions.
However, despite the lack of absolute precision, measurements with this device will be in the ballpark and can begin to quantify for comparison some of the design characteristics that have been previously discussed only in qualitative terms. The new data may be approximate, but now we have some numbers to discuss.
I'll be including new data in upcoming posts so we all can get a better grasp on razor design and the process of matching razor and blade to our own beards.
