Thread: Verhoeven Paper Question

+1.

The shave is our goal and there simply is no standard way to quantify, by measurement units, a "smooth shave" and/or "a sharp shave". If 5 users test the identical razor they will all likely give differing reports because of their own beard variations, technique, soap, etc... Our own faces are the best test, and each face will have distinct shaving preferences and qualities. So even identical edges won't result in identical reports because our most meaningful "testing device" (i.e. our faces) all have a different "calibration"; so to speak.

Let's say we use a surface tester to measure the striations on different bevels. A better RMS result doesn't necessarily mean we'll get a better shave. So is there really any point in measuring the surface finish of a bevel? Another area to test and perhaps interesting when comparing different hones. But, to me, it would only be interesting if it somehow relates to the shave.

How to make any edge measurement result correlate to real-world shaving comfort or efficiency is a major problem that I don't see a solution to.

I wonder if a high-grade analytical balance could detect a weight difference in a razor after say 100 laps on linen. If so, then this could add some data to the discussion. Like this:
1. weigh razor
2. strop on latigo 100 passes then weigh again
3. strop on linen 100 passes then weigh again
4. strop on newsprint 100 passes then weigh again
5. strop on newsprint dusted with CrO, 100 passes then weigh again

You would need to wear latex gloves and keep the razor clean. Sweat and oil from the skin would probably weigh more than the lost metal.

We should also not forget that the quality of the shave is in the barber, not the blade.

You mean like the old saying,"It ain't the arrow, it's the Indian".
