Sharpening angles

As one of the few professional sharpening services in the region, our in-depth knowledge of the different blades and our mastery of sharpening angles enable us to provide a high-quality service tailored to each tool.

Sharpening angles refer to the inclination between the blade and the sharpening surface (such as a whetstone, grinding belt or other sharpening device) during the sharpening operation. This angle is crucial, as it determines the sharpness of the cutting edge and the cutting performance of the tool or blade.

A sharper (smaller) angle makes the blade sharper, but also potentially more brittle, while a more obtuse (larger) angle offers increased durability at the expense of some cutting acuity. Sharpening angles vary according to the type of tool and its intended use:

Kitchen knives

angles can vary from 15 to 20 degrees per side for Western knives, while Japanese knives can be sharpened to even sharper angles, around 10 to 15 degrees, due to the hardness of their steel.

Pocket knives and multi-purpose tools

these are often sharpened at an angle of around 20 to 25 degrees per side to balance sharpness and strength.

Axes and machetes

for these tougher tools, sharpening angles are generally around 30 to 40 degrees per side.

Sharpening without overheating steel

We master the best techniques for sharpening and honing your blades without ever overheating the steel.

To do this, we use variable-speed equipment to avoid overheating, which alters the quality of the steel, thus preserving its integrity and prolonging the life of your tools.

Variable-speed machine sharpening

Our workshop is equipped with state-of-the-art sharpening machines, designed to efficiently process a wide variety of tools.

These machines, known as grinders, feature variable-speed settings, enabling us to adjust the sharpening speed to suit the type of steel and tool.

This precision in speed control minimizes the risk of overheating, preserving the quality and longevity of your blades.

Sander sharpening is particularly suitable for following different processes to achieve exceptional results:

First pass with sandblasted abrasive belts

The first step is to use appropriate grit sandpaper to gently remove imperfections and create a uniform base on the blade. This process removes irregularities and prepares the tool for precise sharpening.

Use abrasive belts to remove scratches

Following the first pass, we use a finer paper to remove the scratches left by the initial sanding. This step is crucial to refine the blade’s surface and ensure a smooth transition to a perfectly smooth finish.

Mirror-finish polishing : leather strap and polishing paste

The final stage of our premium sharpening involves meticulous polishing with a special polishing paste and leather strap, ensuring a brilliant mirror finish. This process not only improves the blade’s appearance, but also optimizes its cutting ability.

The advantages of variable-speed machine sharpening

Steel preservation

this method prevents thermal alteration of the steel, ensuring that the blade retains its hardness and resilience.

High-quality finish

variable-speed machine sharpening delivers an exceptionally smooth finish and a sharp blade, ideal for tools requiring extreme precision.


whether for delicate kitchen knives or specialized blades, variable-speed machine sharpening adapts to a wide range of tools and needs.
