The amount of time required will vary when a knife is sharpened for the first time with the Billy Knife Sharpener, depending on the condition of the blade and the quality of the steel. On average, it takes 60 seconds. The edge must first acquire the chosen 15° or 20° grinding angle. However, thanks to the constant grinding angle, only a few rolls back and forth are needed for subsequent resharpening.

The discs on the Billy Knife Sharpener are designed to last for years with regular use. In the rare event that you need a replacement, we’ll send one to you for free! Simply send us an email, and we’ll take care of it.

Enclose the Billy Sharpener firmly with one hand. With the other hand, the desired grinding wheel is turned up in an opposite movement. After changing the grinding wheels, the grinding wheels should again be mounted on the roller grinder with the screws tightly screwed down by hand.

To remove grinding residue of the diamond and ceramic discs, cleaning with a pencil eraser is sufficient. If necessary, the diamond grinding disc can be unscrewed and thoroughly washed in warm water, with a little washing-up liquid and a brush.

To grind particularly broad blades, where the cutting edge stands higher than the grinding disc, elevate the sharpener with a suitably thick cutting board to ensure contact with the cutting edge is within the radius of the diamond grinding disc.

In principle, kitchen knives of any quality can be sharpened at 20°. However, depending on the condition of the blade and the quality of the steel, many knives can be sharpened to an even finer edge at 15°.

You do not need water to sharpen knives with the Billy Knife Sharpener because no significant heat is generated due to the smooth rolling movements. The diamond coating is also designed just to be used dry.
