Here is my photo analysis on how blade parameters change with the Phoenix Artisan Accoutrements (PAA) Double Open Comb (DOC) satin safety razor when a Wilkinson Sword blade is loaded all the way to one side or the other of the razor head for minimum or maximum blade reveal. http://imgur.com/a/D7LZq http://imgur.com/a/YV5Li Minimum Blade RevealMaximum Blade RevealBlade Angle (deg)26.925.1Blade Exposure (mm)-0.27-0.12Guard Span (mm)2.221.80Cap Span (mm)1.882.18Blade Gap (mm)0.510.46Blade Reveal (mm)1.111.36 This might be the first time that anyone has ever documented and measured how blade exposure, span, etc., change for a razor with respect to the razor's slack in seating a blade. For the PAA DOC with a Wilkinson Sword blade, the blade exposure increases from -0.27 mm to -0.12 mm and the guard span decreases from 2.22 mm to 1.80 mm with a blade reveal that increases from a minimum of 1.11 mm to a maximum of 1.36 mm. It is common that some slack is present when loading a DE razor blade, typically resulting in some noticeable asymmetry in blade reveal, etc., between one side and the other of the razor head. Small manual adjustments are, therefore, often necessary during loading to make the blade parameters fairly symmetric around each blade edge. Blade exposure is the most sensitive blade parameter in that blade exposure changes the most in percentage with respect to changes in blade reveal. In the case of the PAA DOC with a Wilkinson Sword blade, for example, blade exposure magnitude decreases by 56 % as the blade exposure increases from -0.27 mm to -0.12 mm at the extremes, or blade exposure magnitude increases by 125 % as the blade exposure decreases from -0.12 mm to -0.27 mm. Other blade parameters change, as well, when adjusting the blade during loading, but the blade exposure changes the most relative to itself, and since blade exposure is the most important parameter in how a razor-blade combination feels and performs, the photo analysis shown here highlights the importance of loading a blade as evenly as possible for consistent shaves. The photo analysis that I performed was done for the PAA DOC because it is the only razor that I have with slack in loading the blade. (I started wet shaving on June 12th and my only other razor right now is the Dorco PL602, which automatically loads the blade very evenly.) The Wilkinson Sword blade was chosen because its blade width is precisely 22.0 mm, as best as I have measured and verified on the Internet. Given my lack of experience, I don't know whether the blade-loading slack with the PAA DOC is large, small, or around average. Photo analyses of blade parameters for minimum and maximum blade reveal could be done for other razors, by myself or by others in the future, but analyses like this are more educational than practical since wet shavers generally strive for even blade exposure. There is an interesting exception, however, that comes to mind and might justify such analyses: purposefully loading a blade to one side to intentionally create a relatively more aggressive side with more blade exposure and a relatively less aggressive side with less blade exposure. I'm not sure how practical that would be, but it is an interesting thought, nonetheless. Regarding analysis details, it should be noted that the same side of the razor was used in the photographs to avoid potential geometric differences between the two sides of the razor that would likely result in slight differences in blade parameter values. I would also like to mention that the measured blade angles of 26.9 deg and 25.1 deg and the total spans (guard + cap) of 4.10 mm and 3.98 mm are certainly different due to measurement error, but the measurements are relatively similar, which serve as evidence that the analysis is good. The analysis is not perfect, though. The measured difference in blade reveal of 0.25 mm, combined with the measured blade angles, leads to a calculated difference in blade exposure of 0.11 mm. My measured difference in blade exposure of 0.15 mm is not far off, especially when considering measurement and roundoff errors, but the error is present.
