Every brand and every pattern of scalers and curettes have one thing in common...the angle between the blade face and the lateral surface,
as shown below...
With InstRenew, you'll maintain the correct angle every time you sharpen your instruments. And it's easy! As easy as...

POSITION THE BLADE The Blade Positioner automatically locks EVERY instrument into the correct position for sharpening by holding the blade face horizontal.	GRASP THE TIP The Tip Clamp allows you to easily grasp the instrument on any straight portion of the shank and maintain the correct position while you sharpen.	SHARPEN THE BLADE The Sharpening Cone is cut at the correct angle for EVERY brand and EVERY pattern of scalers and curettes. Simply trace each cutting edge over the sharpening cone.
