Sharpening Tool "slider"
Knife sharpening with whetstones is a
centuries old craftsmanship. The SLIDER
brings this skill into the home kitchen.
Expensive and valuable knives can be
sharpened at an angle of 14 degrees by left
or right handed users without any problems
and the blades cannot be scratched. Our top
priority was to design an ergonomic
innovative tool which is both, simple to use
and highly functional. The high-quality
stainless steel body made in Solingen, the
food-safe silicone and the abrasion-proof
ceramic inserts combine, to create a precise
and effective working unit.

Amateur cooks often fear that the use of
conventional sharpening tools will scratch or
damage their valuable knife blades. If they
do not want drawers full of dull and damaged
blades they can now sharpen their knives more
effectively and safely with the SLIDER.
This new tool brings the Solingen tradition
together with the centuries old craftsmanship
into the home kitchen making them available
to the domestic customer. A wedge made of
stainless steel fixes the blade at an angle
of 14 degrees permitting even sharpening of
the blade. A silicone surface of the wedge
prevents the blade from slipping.
Ceramic inserts are fitted to the underside
of the wedge, allowing the blade to be guided
along a traditional sharpening stone. This
means that knife sharpening becomes a routine
event rather than a test of courage.
The company Wüsthof is located in Solingen
and the blades which they produce are known
worldwide for their quality and high
durability. The SLIDER is manufactured in the
same tradition. The high-quality stainless
steel body, the food-safe silicone and the
abrasion-proof ceramic inserts combine, to
create a precise and effective working unit.
The shape of the SLIDER derives from the
direction of the movement. The abstracted
arrow heads form the body of the wedge and
create an ergonomic recessed grip. Small
holes in the silicone surface allow the water
and the grinding sludge to be absorbed.
Curved edges on the stainless steel wedge
ensure a comfortable grip and reduce the risk
Our top priority was to design a tool which
is both extremely simple to use and highly
functional. The SLIDER needs neither to be
fixed to a work surface nor awkwardly
fastened to the blade of the knife. Its
dimensions and proportions allow
straightforward and cramp free usage.
- the SLIDER is placed lengthways on the wet
- the knife is placed transversely on the SLIDER
- with gentle pressure the blade and SLIDER
are moved forwards and backwards along the
length of the sharpening stone.
- the knife is sharp
With the SLIDER fixed at an angle of 14
degrees, anyone can accurately and cleanly
sharpen different sized knives. Different
sizes of knives can be easily held by the
guide hand without the blades being
scratched. By using the SLIDER expensive and
valuable knives can be sharpened by left or
right handed users without any problems.
The different elements of the sharpening tool
(SLIDER) can be easily separated and are
fully recyclable. The SLIDER has a long shelf
life and is very durable. Knives which are
sharpened with the SLIDER can be used
repeatedly and over a long period of time.
This avoids frustration and the need to
prematurely replace expensive knives – a
positive feature in the life span of this
