Why wet sharpening?
Because it is gentler…..

Our sharpening techniques

Choosing the right focus method is not easy for you? On the one hand cheap, on the other hand durable?

The cheaper and coarser dry grinding requires significantly less grinding and time compared to wet grinding. However, the sharpness of the cutting edge has to be repeatedly treated during dry grinding and the material of the knife shrinks much faster.

Here you can find out everything about wet and dry grinding, as well as about thinning your blades.

The suffering of blunt work is over!

Dry Grinding

We must also mention the disadvantages of dry grinding here.

Dry grinding means that material without the use of a coolant, e.g. Water that is removed. A lot of heat is generated at 2,350 – 6,900 rpm. And that is one of the disadvantages of dry grinding: An inexperienced grinder can get the tool too hot when grinding – the steel tarnishes (blue). In this area, the steel is brittle and breaks out particularly quickly.

Here are two examples:

Our years of experience help to avoid such mistakes when dry grinding.

We treat the material gently without overheating during grinding. But despite all this, we always recommend the …

Wet griding

The wet sanding step is more time-consuming, but it has several advantages. Because here each knife is individually adjusted and treated with an auxiliary tool to its grinding angle. The step in wet grinding is more time-consuming, but it stands out due to the above described with some advantages (see below) and your tool is much more durable.

You should take this into account in your cost analysis!!!

Refinement of the blade

Here, at a lower torque (96 rpm) of the grindstone, both the rotating stone with a 220 grain and the steel to be grinded are cooled with water. The wet grinding is therefore very gentle and there is no risk of the steel overheating. Another advantage is that less material is removed from the object when gently grinding – this extends the life expectancy of your tool. However, wet grinding takes more time due to the gentle treatment.

Refining the blades
is always done with a wet grinding, first on a 220 stone, then on a specially made Japanese 4,000 water polishing stone. For all cutting edges that are ground on a rotating stone, the refinement ensures that an invisible micro-chamfer is created during the honing and polishing process with subsequent use of the leather honing wheel, which ensures a beautiful mirror effect. Then a Japanese camellia oil is applied to your tool, which is food-compatible and forms a protective film. Japanese camellia oil does not stick and does not attack the surface and is therefore an ideal protection for blades that should be stored for longer.

In addition, you can also have slight to moderate scratches removed at an additional cost. While this is time consuming, it prevents the development of bacteria in the micro scratches.
