This knife holder was developed by pathologist, David Pinkhasov PA, PhD. It has a simple design that allows the handles to protrude for safe gripping. The double tubes make it easy to organize your instruments, and the angled notches keep the knives separated and ready for use. Simply place your sharp knives in either slot to be kept out of harms way. This holder will accommodate multiple knives of virtually any size and features a perforated base for drainage. It is made from durable heavy-duty plastic to ensure a long life and reduced dulling of your dissecting knives.
