Re: Opinions Wanted " No, No, Not Hardness "
In my Opinion the "*" is unsuitable as a hardness test probe.
Hardness testing is performed with a conical probe calibrated for depth of penetration as an indicator of relative hardness to preset standards.
Usually Brinnel Scale.
An object such as an "*" , has no linear or other progressive penetration capability and would be impossible to calibrate.
Sorry to burst this balloon but the answer is elsewhere !
