    What do you mean by "positive blade exposure"?

    It's a defined term, positive means extending beyond the shaving plane [​IMG]

    How does this factor into "aggression"? Positively, I'm assuming?

    Positively yes. Super aggressive razors like the Ikon Tech get their aggressiveness from exposure, not gap.

    Adding to the conversation about the base plate bumps that were added to the micromatics and other later models , they do raise the angle of the blade a little more than I thought it would.
    The older blades did have a thicker spline but not this much clearance underneath, I have a older blade and of coarse the better newer Personna SS Ptfe blades.
    I have two MMOC razors and one has the bumps and the other with out bumps. I think the A.S.R company engineers wanted a more lifting angle for spline inperfections and possibly a better and smoother less aggressive shave is the reasoning IMO.

    As you can see the bumps lift the GEM Personna SS PTFE a lot more.(both pictures of comparing are using the same Personna SS PTFE blade.)
    It should make a little difference in angle of approach to technique while shaving IMO.

    Wouldn't the dimples also make the blade more rigid? Might not matter with the double edge blade if they laid flat.
