The TurnBox family is a very stable and compact knife sharpening system. It works well in the kitchen and it quickly breaks down for storage in a drawer. The TurnBox family of knife sharpeners is also great for outdoorsmen on the go because it is lightweight and stores easily in a backpack. It only takes a few swipes to maintain an edge (a bit more if you have a really dull knife). This sharpening system features a hardwood turnbox and both 20 and 25 degree pre-drilled holes for the rods. The end of the box twists open to provide a storage area for the two ceramic rods.FeaturesHardwood turn-boxInternal rod storage20 and 25 degree pre-drilled holes for rodsTwo 5" medium grit alumina ceramic rodsTwo 5" fine grit alumina ceramic rods
