These full size Tri Hones offer the solution to one of the major obstacles to knife sharpening-keeping the blade at the proper angle to the stone. The included 23 degree sharpening guide helps keep the knife blade at the perfect sharpening angle. This 3 stone model comes with Coarse (Silicon Carbide), Medium (Soft Arkansas) and Fine (Hard Arkansas) stones.
The different stone grades are as follows:
Silicon Carbide (Coarse): man-made stone that is much coarser than any of the natural Arkansas stones. This is the stone to use on very dull or damaged edges.
Soft Arkansas (Medium): coarsest, most versatile and most popular of the Arkansas stones. Soft Arkansas stones are used to quickly put an initial edge on dull or neglected knives or other cutting tools. This is a natural stone and color can vary from white to gray/black to pink/gray, or a combination of these colors in a single stone.
Hard Arkansas (Fine): used to establish and maintain a keen edge on cutting tools. This natural stone color can include Grey, White, Black/Grey, Grey/Pink, Black/ White, White or White/ Pink, or a combination of these colors.
One ounce honing oil in included.
All Tri-Hones comes with a wood base.
