    You know what I'm talking about.

    Default Making Progress

    I talked to my boss whom owns the SEM and he said that he will be willing to let me use it in order to conduct a few experiments about straight razors. Now I have to find the time to come up on my end.

    Let's talk about some Ideas of what experiments we would like to do and our controls of the experiments and what not.

    I think that we could continue these thoughts in this thread and eventually make a design for the goals that we want to accomplish and how we will accomplish them.

    Default Ideas so far.

    Here are some Ideas and volunteered propositions.

    And a whole bunch of other questions, concerning hones and their abilities too.

    ...shooting pictures fresh off the hone, after the first stropping session on leather, right after the first shave, and after allowing the edge a day of rest), would you be prepared to run them, for the benefit of the whole SRP community?

    Does it remove burrs left over from the honing process? Does it actually remove metal and sharpen the very edge? Does it remove corrosion? Does it strip an molecular layer away, giving us fresh metal? Does it realign the bevel?

    To the OP: If you need more razors to test, I am more than willing to donate some to experiment on. Same rules as Jimmy, I want them back once the tests are over.

    I can even send over razors that have been used x amount of time with no stropping in between and a razor fresh off the hones. Then you can strop it and see before and after pics. But, you'd of course have to post pics for us.

    Can anyone else think of unanswered questions that would be great to be answered by the closer look an SEM can provide?

    Thanks for sharing these.

    As said above, please also take the time to throw in a nice new DE blade to see what that looks like.


    One of the sharpest and smoothest cutting (for me anyway) DE blades I've used was a Feather.

    Looking at it at 200x and 500x was a bit of a surprise, as it does not look all that smooth and sharp to begin with.
    Those are the first two pics.

    Then there is the Merkur DE blade, which to me felt horribly scratchy and always left my face very irritated. also shown here at 200x & 500x pics 3&4
    If my straight's edge looked like that, I'd throw it in the bin!

    That last one looked like the surface of the moon. Oddly enough when I used to shave with DEs although I preferred Feathers I was in the minority who got close and comfortable shaves with the Merkur Super.

    These hi res photos remind me of what was said about making sausage. If you see it done you no longer want to eat it.
    Be careful how you treat people on your way up, you may meet them again on your way back down.

    Massive potential for worthwhile experimentation here!!! Just a simple starter that I would like to see would be a scan before and after 3050 laps on a Tony Miller latigo strop.

    That will be a problem I believe, as I don't have one of those.

    We need to work out an issue. Would it be okay for an individual to send their razor after stropping to be looked at in the SEM? or is that time lapse too long... I think it may be too long as I usually wait until the lather is on my face to stop my razor.

    Alright, I am starting a new thread for the experimentation part.

    The new thread is located here
