The way the handle is designed is the best way to use the removable tips. It is a usual dimension stainless steel handle. The ends of the handle have patented, double undercuts that can help with maximum retention of the tips. This is the working end of the instrument. During use, the professional has more confidence. Even more so, the rounded end of the instrument will help direct the forces evenly along the fitted surface of the silicone. The rounded end will also help reduce too sharp of a working end that may puncture through the silicone tip while using it. The single use tips can easily be placed on before use and discarded after use.
