For most if not all bushcraft and survival tasks a knife is an important tool and to keep it at its best for when you need it most you need to keep it sharp. While away I use a lansky ceramic pocket crock stick sharpener as it takes up very little space and can also be used to sharpen fish hooks, then if you take one of the ceramic rods you can sharpen a serrated blade too.
When at home I use the lansky knife sharpening system, it gives me control over the angle of the edge and the variety of stone courses allow you go from grinding out chips in the blade with the extra course right down to a polished edge that you can see your reflection in with the sapphire hone. I currently have the following hones: extra course, course, medium, fine, ultra fine, sapphire polishing hone and a serrated blade hone. I go eight times over each side of the blade then eight more alternating the side as I go working my way down the stones.
