Not to split hairs ( :D LOL, oh gods I slay me :D ) but shaving is a different action than the HHT. Since the skin is indeed holding the root and the blade is lightly pressing the skin during the shave, it's actually a shearing action. The HHT cannot be said to shear since there is little counter force on the hair, just its own resistance based on the physical properties of the individual's hair and the length at which it is held.
