Common monofilaments are variably sharp from one application to another.  Softip monofilament nerve testers are not sharp (re: patent).  With Softip, sharpness cannot be used as an invalid cue in solving the touch-detection task.

Small-diameter nerve fibers respond to sharpness; these are the same neural fibers that are resistant to the most usual causes of neuropathy.  Softip nerve testers are more sensitive to the large-axonal neuropathies (e.g., compression, diabetes, laceration, etc.) than common monofilaments.

Because of specific properties of various body parts, several sets of Softip monofilaments are available.  For example, loss of protective sensation (LOPS) on the hand is often taken to be failure to report 4 g, whereas, for the foot, loss of protection sensation is failure to report 10g.  Similarly, the exquisite sensitivity of the face suggests that lower-force Softip monofilaments can be used to detect and grade neuropathy.
