I know the 10g is the constant pressure applied, but what does the 5.07 represent? the gauge of the wire? Help me out, I forgot lol...Thanks

5.07mm diameter?
That would be a pretty thick monofilament!!
It indicates the 'stiffness' of the monofilament. The bigger the number, the stiffer the monofilament.
"The history of the use of various filaments to test for the presence or absence of sensation dates back to the 1800s when Von Frey used horsehairs for testing patients sensation thresholds. In 1960, Dr. Josephine Semmes and Dr. Sidney Weinstein developed a more sophisticated set of medical grade sensory testing monofilaments.¹ Their premise was that an increased diameter of a monofilament would be accompanied by a required increased force needed to create a bend in the monofilament when it was applied to the surface to be tested. They created a progressive scale of monofilaments for neurologic sensory testing. Monofilaments are assigned numbers that range from 4.17 to 6.10. The higher the number, the stiffer the filament. The formula utilized is as follows: Marking = (log10 Force(in mg) x 10). The 5.07 monofilament has been accepted as the medical standard for screening of the minimum level of protective sensation in the foot. The reproducible buckling stress force required to bend the 5.07 monofilament is 10 grams of force.²"

Well it no longer means what it meant.
Originally, it meant log base 10 of force +4. You had to ask. During a test by the feds, original version and some perverted version by someone else were averaged to come to around 10 g, so "they" decided the 5.07 should be 10g.
Generally, those Semmes-Weinstein numbers mean log base 10 of the force expressed in gram-force then plus four. Really, there was a reason for that.
1. Don't pay attention to non-math majors when it comes to this stuff.
2. Don't care what the SW numbers mean; just look to the gram-force.
