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 in a backpack. It only takes a few swipes to maintain an edge (a bit more if you have a really dull knife). Shipping Length: inch X Shipping Length: 5.0 inch X Shipping Length: 1.2 inch X
