We need to quantify the sharpness of a particular surgical instrument to
determine its life span. (a shaver for arthroscopic knee surgery). We can
take high magnification pictured and document the edge wear, but not sure if
we can quantify that to accurately. Also, I have read studies which
measured sharpness of instruments by cutting certain tissues (cornea) to a
particular depth and measuring the amount of force it takes.

Does anyone know of any other method besides the two I mentioned to
quantified sharpness?

I will post the responds if there is interest.
