In close combat it is possible for your hand to slip off the grip and hit the inside of your metal guard causing injury to your thumb. The S89 pad is made from special 10mm thick high density impact absorbing foam. The foam is designed to have very good pressure distribution and energy absorption properties. Any impact of the thumb against the guard and the force is distributed over a wide area, which dissipates the energy without causing injury.
