When your Kamui Tip has been under extensive use and is not like it was when it was brand new, then give it a little agitation from the Kamui Gator Grip. We recommend only using the Kamui Gator Grip with your Kamui Tip. The inner plate is made of stainless steel and will last you many years. The exterior is made of real Box Wood. The Kamui Gator Grip is the only tool you need to do proper maintenance for your Kamui tip. We know that once you have tried our tip tool you will understand that the other tip tools out there were meant for tenderizing your average steak!
