Our whetstones in detail
Professional sharpening with our whetstones
Sharp blades don’t just make cutting a pleasure - they also enhance safety. But even the finest edges eventually become dull. With our ULTIMATE Whetstones dull blades are a thing of the past.
These sets bring your knives to a level of sharpness that can split hairs and help maintain that edge over time.
Thanks to their superior sharpening performance, Culilux whetstones aren’t just trusted by professionals, they also make it easy for beginners to achieve excellent results quickly.
ULTIMATE Whetstones

Made from high-grade aluminum oxide with a magnesium bond, they deliver outstanding sharpening performance, minimal wear, and an exceptionally smooth sharpening feel. Specially manufactured for us as custom versions of the renowned Japanese NANIWA Chosera stones, they are recommended for anyone who values true premium quality — from ambitious beginners to experienced users.
Components of the bundle

WHETSTONE 400 GRIT
The 400 grit has the fastest speed of abrasion and is used to grind the cutting edge into the desired shape and angle. It's also used to repair a chipped cutting edge.

WHETSTONE 1000 GRIT
The 1000 grit is used to refine the surface of the cutting edge after sharpening on the 400 grit. When the edge is only worn slightly, sharpening can also be started on this grit.

WHETSTONE 3000 GRIT
The 3000 grit is used to further refine and pre-polish the cutting edge. It can also be used to restore the sharpness when a leather strop can't bring the edge back any more.

LEATHER STROP
The cutting edge receives its final refinement and polish on the stropping block.
A polished cutting edge glides through food with little resistance and not only increases the perceived sharpness, but also the measured one.

SHARPENING BASE
The sharpening base made of durable plastic with non-slip rubber feet ensures a secure hold during sharpening and prevents the stones from slipping.
It’s also perfect for storing the ULTIMATE whetstones – neat, stable, and practical at the same time.

CLEANING STONE
Over time, the pores of the whetstone become clogged, which reduces the cutting performance. The diamond cleaning/ dressing stone cleans quickly and effectively, restoring the stone’s original sharpening efficiency.
Benefits of our whetstones

MAXIMUM EFFICIENCY
Made from high-grade aluminum oxide with a magnesia bond, ULTIMATE whetstones offer high density and exceptional efficiency. Material removal is particularly fast, allowing visible sharpening results in a short amount of time. At the same time, a pronounced burr forms quickly, which makes sharpening significantly easier, especially for beginners.

READY TO USE INSTANTLY
The high density also reduces the porosity of the material. As a result, the stones absorb very little water and, unlike many conventional sharpening stones, do not require prolonged soaking. It is enough to briefly wet the ULTIMATE whetstones with water. This characteristic is also known as “Splash & Go”.

SAFE AND STABLE
Many whetstones are designed for double-sided use. As a result, dishing develops on both sides over time, causing the stone to no longer sit flat and to wobble during sharpening. This makes sharpening more difficult to control and can negatively affect the result.
ULTIMATE whetstones are designed so that little to no dishing occurs. This allows them to remain stable, prevents wobbling, and enables safe sharpening with high control, pressure, and speed.

LOW WEAR
Thanks to the hard magnesia bond and the high material density, wear is minimal. Even at a thickness of 15 mm, the stones offer an exceptionally long service life. Their low wear also helps them retain their shape for a long time, so little to no dishing occurs. This makes sharpening easier and more precise.
The art of sharpening

SHARPENING
1. During sharpening, material is removed from both sides, in order to obtain a pointed cutting edge again.
2. The knife is held at an angle of approx. 10-15° to the stone.
3. The blade is moved back and forth at a 45° angle to the stone until a burr is created along the entire edge.
4. On the rear side only, the rear end of the cutting edge must be moved at a 90° angle.

REFINING THE EDGE
As soon as a burr is created on the coarsest grit, the cutting edge is refined by sharpening on the finer grit stones, which increases the sharpness.
As on the other stones, it is recommended to sharpen the blade in 3 sections, first the tip, then the middle, and finally the heel of the blade.

DEBURRING / STROPPING
After sharpening on the finest stone, the cutting edge must be completely deburred. This is done by stropping, with alternating strokes (front and back) first on the finest stone and then on the leather stropping block.

EDGE MAINTENANCE
To maintain the sharpness, the knife must be stropped on the stropping block as soon as paper or a tomato can no longer be cut cleanly.
If stropping is no longer sufficient to restore the sharpness, it must be sharpened again on a whetstone, using the 6000 or 1000 grit, depending on the condition of the cutting edge.
