The Diamond/Ceramic 4-Rod Knife Sharpening System features a hardwood turnbox with rod storage in the base, two medium diamond rods & 2 fine ceramic rods.

The Turn Box 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 turn box family of knife sharpeners is also great for outdoorsmen on the go because it is lightweight and stores easily into a backpack.  It only takes a few swipes to maintain an edge (a bit more if you have a really dull knife). 

There are two pre-set knife sharpening angles in the wood block 20 degree & 25 degree

25 Degrees - This is used for most kitchen knives and provides a sharp, durable edge.

20 Degrees - This is used for those desiring a very sharp edge.  Some examples would be for filet knives or cutting tomatoes.  Lower degrees result in sharper knives, but require more regular maintenance.

This 2-Stage Knife Sharpening System features a hardwood turnbox with internal rod storage in the base, two 5" long medium diamond rods (600 grit), and two 5" long fine ceramic rods (1000 grit).
