With the TWINSHARP knife sharpener

ZWILLING J.A. HENCKELS has developed some very easy to use sharpening devices. The TWINSHARP Select knife sharpener makes life so much simpler and safer.

The TWINSHARP Select can be used by right- and left-handers alike. Draw the blade in one single stroke only, applying only little pressure. Draw the blade with your hand only towards the body, do not tilt the blade.








This innovative knife sharpener with its two separate sharpening modules sharpens knives simply, safely and effectively. It is easy to use because, in contrast to the sharpening steel, the angle is pre-set. Thus it is nearly impossible to use this sharpener the wrong way. Using its steel wheels, module 1 is able to gently remove small damages to the edge. Module 2 gently smoothes the edge and restores the knife to its high sharpness. Above all TWINSHARP Select works equally for left- and right-handers.

TWINSHARP® Select instruction manual

Prior to using your new knife sharpener, please read this manual carefully to avoid damages to knives and/or sharpener. This knife sharpener may only be used for uncoated knives with a straight edge. It comprises two modules which are marked as follows:

  • Module I with steel wheels for coarse sharpening and pre-sharpening respectively
  • Module II with ceramic wheels for fine sharpening and smoothing.

How to use it:

  • Place TWINSHARP Select on an even, non-slip surface. The knife blade needs to be clean.
  • Take hold of it with your left or right hand so that thumb and index finger will touch and press it slightly onto the surface.
  • Place the end of the cutting edge (near the handle) in a 90° angle into the respective module. Draw the blade with little pressure towards you. Depending on the degree of bluntness, you may have to repeat the process up to five times.
  • If your knife is very blunt, use module I first and then module II. Knives with only a little degree of bluntness may only require the use of module II to return it to its original sharpness.
  • Check the result by cutting into a sheet of paper.

Important note:

  • No fluid is needed to sharpen knives with the TWINSHARP Select.
  • To clean the TWINSHARP Select, simply turn it upside down to get rid of the residual sharpening dust. Use a dry soft cloth to wipe it clean. Do not soak it or put it in the dishwasher as this might damage the sharpener beyond repair.
  • Never try to open your TWINSHARP Select.
  • Avoid dropping the TWINSHARP Select as it might get damaged.
  • TWINSHARP Select is not suitable for specialty knives or scissors.
  • The pre-set angle of the sharpening wheels is for household knives only. To sharpen Asian knives a different angle might be necessary.

Please note: Sharpening knives is potentially dangerous. ZWILLING J.A. HENCKELS cannot be held responsible for any possible damages.

With the TWIN® Stone Pro

The TWIN Stone Pro is a sharpening stone specifically developed for the blades of ZWILLING J.A. HENCKELS knives. This stone gives them the desired “Asian sharpness”.

Instruction manual TWIN Stone Pro

Please read these instructions carefully prior to first use to prevent any possible damages to knife or stone.

This combination stone comprises two different layers: the dark side for coarse sharpening and the light one for fine sharpening.

The dark side is used on a blunt knife or to remove small dents in the blade. The best degree of pre-honing is achieved when a little burr becomes visible on the edge (fig. 4) which is subsequently smoothed off.

  • Remove the stone from the box.
  • Soaking the stone is not necessary; a few drops of water to whet the surface will suffice.
  • Put the stone back into the lower part of the box and place it on a non-slip, level worktop.
  • Move the knife across the stone in steady movements as shown in fig. 2 + 3, with the tip first.

Note: Make sure that the stone always stays wet. Do not remove the paste while sharpening as it helps sliding the knife across.

  • Knives with an asymmetric edge should be placed fairly flat upon the stone and sharpened with this angle (fig. 6).
  • Repeat the process with the smooth side of the stone (fig. 5).
  • Check the result by cutting a sheet of paper.
  • When the knife has reached the desired degree of sharpness, remove the grinding paste by cleaning the knife under running water and dry it carefully with a towel.
  • Clean the stone under running water and let it dry completely before you put it back into the wooden box.
  • Do not let the stone drop as it might get damaged.
  • If the surface of the stone becomes uneven, use fine sandpaper and water to smoothen it.

Please note: The sharpening of knives is a process which comprises a risk of injury for which ZWILLING J.A. HENCKELS cannot be held be responsible.

Here are a few tips to prevent premature loss of sharpness:

  • Never use any hard cutting surface like china, metal, marble or granite.
  • Best clean your valuable ZWILLING J.A. HENCKELS knives by hand - if you put them in the dishwasher the blades could get damaged by other items.
  • Never use your knives for other purposes than they are intended for - i.e. do not use them for opening cans or as a tool.
