KIKUSUMI Ceramic Knife Cutting Guide

CERAMIC KNIFE CUTTING GUIDE

[NOTE:  The following article is also available under SUPPORT on the top menu]

It is important to note the differences between steel and ceramic knives.  They are different materials and are made in different ways and yet both can be used to cut effectively.  For this reason our team at Kikusumi has decided to craft a ceramic knife cutting guide and hopefully improve our customers knife skills in the process. Ceramic knives have more in common with the hardest of forged steel knives such as those crafted in Japan with blue or white steel.  The primary difference with ceramic is the light weight, non-reactive quality and smoothness of blade (no burrs).

Hardness in steel is measured by the Rockwell scale with high-end steel measuring above 60.  Ceramic is even harder and with hardness comes better sharpness retaining characteristics along with blades that are more brittle.  That is great for slicing but means they should not be used for flexing or cutting hard objects like bones.  Household knives such as flexible boning knives are made with softer steel such as VG10 and sharpened at wider angles.  Softer material knives lose their sharp edges quickly which means more frequent sharpening.  The advantages of hard material knives make them better choices but along with it comes a greater need to learn to use them properly.  Following are some cutting guide tips and actions to avoid when cutting with hard material knives like ceramic.

Any knife that is dropped risks damage or breakage.  The more brittle the knife, the more likely it will chip or break when used improperly.  Dropping a knife is to be avoided at all costs.  Keep in mind that ceramic knives are designed for vertical strength and are never intended to be impacted from the side or flexed.  When used correctly ceramic knives will not chip or break and should last for years.  The key is to use them strictly for slicing and take advantage of the entire length of the blade.

We have created a ceramic knife cutting guide that illustrates the proper cutting technique for hard and soft foods when using ceramic knives.  Using these Japanese slicing techniques rather than simply pushing the blade down through food utilizes more of the blade for easier cutting, longer blade sharpness and results in less pressure on the handle-blade joint.  This is the way a Japanese chef would cut – using the strengths of the blade to the maximum.  Never feel you need to use “heft” to cut properly as a good knife combined with good technique is always superior to brute force.

 

Knife Care

Ceramic Knife Maintenance

 

Following a few simple rules will result in your ceramic knife staying sharper and lasting longer.  When you first buy your knife it is sharp and looks great – wouldn’t it be great to keep it that way?  The following is list of Do’s and Don’ts for proper ceramic knife maintenance.



KNIFE CARE

DO
  1. Cut on a wood or plastic cutting board to avoid chipping
  2. Hand wash with warm, soapy water
  3. Allow knife to air dry
  4. Store your knife in its safety cover or a knife block when not in use
DO NOT
  1. Drop ceramic knife on hard surfaces
  2. Cut on stone, marble, metal or glass
  3. Cut frozen food or bones
  4. Use the knife for work that requires twisting of flexing the blade
  5. Apply force to the side of the blade (eg. smashing garlic)


KNIFE MAINTENANCE + STORAGE

  • Store in a knife block / sheath / tray or on a dish drain
  • Use care when storing and removing the knife from a knife block to avoid tip damage
  • Storing any knife upright  (sharp edge up) or sideways in a knife block reduces wear to the knife edge


KNIFE WEAR

All knives will dull over time.  Harder metals like high carbon steels, titanium and carbide tend to hold their edge longer than cheaper steel.  Ceramic blades are harder than any metal – in fact harder than anything except diamond.

Ceramic will stay sharper longer than metal blades with proper knife maintenance.  Over time and extended use micro abrasions or nicks will appear on the ceramic blade’s edge.  This is part of the normal process by which all blades dull over time.  The presence of microchips does not mean the knife is dull – it may continue to cut well for some time after that.  If the knife becomes too dull to use it is time to use a diamond sharpener.  Diamond is the only material harder than zirconium so be sure you or the professional sharpener has one.  The role of the sharpener is to first smooth the microchips on the edge of the blade and then hone a new, sharper edge.  Larger chips and broken tips can often be corrected by sharpening as well – for these it is best to seek out a professional.
