Kyocera Kyotop Damascus
Many Americans got their first introduction to the ceramic knife from celebrity fusion chef, Ming Tsai. Both his Simply Ming and East Meets West programs promoted his use of Kyocera cutlery and the ceramic knife trend was born. These incredibly hard, dense knives offered an interesting alternative to the chef’s traditional steel. The Kyotop is one of the premiere knives in Kyocera’s lineup.
Ceramic knives are produced by pressing zirconia powder and firing them in what is known as a sintering furnace. This process makes for an extremely sharp, hard knife that will never rust and hold its edge for years. Kyocera’s process utilizes a second firing under high pressure and temperature forming what is called Hot Isostatic Pressed, or “HIP” blades. This increases the density of the ceramic material and also gives the blade its distinctive, black Damascus-steel look.
Kyocera’s Kyotop Damascus line features a moisture-resistant, 3 riveted Pakka wood handle and comes with a lifetime of re-sharpening. This is an important point when considering any ceramic knife. While they remain sharp for years, ultimately “microchips” and abrasions will eventually dull the blade. This is not a knife you sharpen yourself. Kyocera will re-sharpen your blade free of charge and ship it back to you (a $10 charge for shipping, you also pay the one-way shipping to them), usually within 2 weeks.
This knife has many favorable reviews from satisfied ceramic knife users. That is an important point we will address in a moment. Reviewers note the Kyotop being scary-sharp right out of the box and were very happy with the overall balance and weight. Several comments addressed the knife being quite a bit lighter in weight than they were accustomed to for that size blade, but that should be expected in a non-steel knife.
The reviewers generally loved the look of the knife and the Pakka wood handles, however one found the handle shape to be a bit straight and square. They felt this made the knife a little uncomfortable for their hand but that it was just a personal choice. Pakka wood handles are being found in a variety of knives these days, including the Shun Classic.
As for the blade, the majority felt that this was about as sharp as a knife can get for cutting and slicing tasks.They cautioned that you should do no prying or twisting as with any ceramic, but for vegetables and boneless meats the edge was the best. A reviewer did remark that over time his has received a few detectible nicks in the blade, which were too small to see but could be felt by running your nail along the edge. To that end, no reviewer rated the sharpening process by Kyocera as anything but exemplary. They stated the service is outstanding and just “adds to the great experience with any of their kitchen knives.”

The Pros And Cons Of Owning A Ceramic Knife
Ceramic Knives
A ceramic knife blade is made out of a material that is so hard that only diamond is harder. That material is usually zirconium dioxide (ZrO2) also known as zirconia. These blades are produced by pressing zirconia powder under high pressure and firing them through a computer controlled sintering process that takes several days. The blade that is produced is sharpened by grinding the edges with a diamond-dust-coated grinding wheel.
To make this blade tough and not too brittle, it is produced by the addition of 3% mol yttrium oxide yielding partially stabilized zirconia. This causes a structural change in the zirconia allowing for a much tougher material.
Several brands on the market now have a black colored blade which is made through an additional “hot isostatic pressing” (HIP) step, which improves the toughness.
Ceramic vs Metal
The only real difference here is the blade material. The blade is the most important part of the knife and with that you have a major difference in a metal blade and a ceramic blade. So what happens when you compare these two materials? You get pros and cons to be sure.
Pros:
• The ceramic material is very dense which means it has a low porosity. This is good for not transferring tastes from other foods. Just rinse under warm water and your blade will be cleaner than if you scrub your metal knife.
• Ceramic material is so hard that only diamond is harder. This means that your edge will stay sharp for year’s vs weeks or months for a metal edged blade. Most ceramic blade manufacturers will even sharpen your knife for free due to low number of times it might be needed. Manufactures of metal blades will never offer this service due to the amount of times it would need to be done.
• Ceramic material is very light and thus you can wield the knife for a lot longer with less strain on your hand and arm.
• And finally, no metal, no rust or pitting or rolling of the edge leading to a dull blade.
Cons:
• Being extremely hard does not mean that this blade is not breakable. Ceramic blades are not meant to cut frozen foods, bones or anything else that is not easily sliced. The tip and cutting edge of these blades can be easily chipped and great care should be taken in ensuring that they are not brought into contact with anything hard.
• The cost of these knives is really in line with high end metal knives. Due to the high cost of manufacture you will not find a low cost version of this type of knife which makes it seem expensive.
• It’s not the most versatile blade in the kitchen but if used for what it is intended, slicing, then you will have a great addition to your knife collection. If you need to cut bones or frozen whatever, use a butcher knife!
Is It Worth The Price
You can buy very high quality ceramic knives for less than a $100. Shopping around for a very high quality metal blade knife and you will pay upwards of $300 or more. As stated above, there is a long and costly manufacturing process and you will not find a cheap knife at Wal-Mart. If you look online you might find some ceramic blades on sale for the smaller paring knives that you might be able to get for $20-$30.
It is also not recommended that you put these knives into a dishwasher. The hard spraying of the water and movement of dishes can cause the blade to come into contact with a hard object like a plate or glass bowl causing it to chip.
The bottom line is if you need a knife to cut veggies and fruit or a blade to cut meat then there is not a better product out there.

Kyocera Revolution Series
Professional Chef’s Knife
The revolution series is Kyocera’s most popular line of ceramic knives. This series has the black oxide blade which creates a tougher ceramic material than the white ceramic blades. These knives are perfect for performing a wide variety of cutting tasks, such as fine chopping and slicing to dicing. The blade has a deeper profile for much greater knuckle clearance for easier use. It has an ergonomic resin handle that is comfortable and provides precise control which makes it so easy to use.
Kyocera has pioneered advanced ceramic kitchen knives. These knives are impervious to juices, acids, oils and salts, leave no metallic tastes on your food which help maintains freshness of your fruits and vegetables. These knives are made in Japan and should only be hand washed and used on a wooden or plastic cutting board.
Kyocera has a 12 step quality control process. One knife will pass through the hands of over a dozen people on its journey through the manufacturing process. Kyocera has spent over 5 decades in perfecting the art of the best and most durable ceramic available today. This is why some other knife manufacturers want Kyocera to produce their ceramic blades for them.
Kyocera has also added a service for their customers to sharpen their knives when it is needed. You just pay shipping and handling and Kyocera will sharpen as many of your Kyocera knives that you have. Everything is sent to a Southern California address where each knife goes through a 5 step sharpening process. Customers typically get their knives back in 7-10 days usually as sharp or sharper than when they were new. The only other recommended way to sharpen these blades is with a Kyocera electric ceramic knife sharpener. This sharpener has a guide the keep the blade straight and uses a high grade diamond wheel.
According to The Cutlery and Allied Trades Research Association (CATRA), an independent testing organization "Recent tests show that the life of a Kyocera ceramic blade without re-sharpening is approximately 15 times that of a typical steel blade." Advanced Ceramic, or Zirconium Oxide, is extremely dense, achieving a much tighter weave than any metal material, resulting in the finest and sharpest edge possible.
About the only thing you have to be careful about when using a ceramic blade is to not use it as a pry bar or try to cut something very hard. It also goes without saying about dropping it on a hard surface. If used correctly, these ceramic blades can last you a lifetime. All Kyocera ceramic products are warranted to be free from defects in material or workmanship for five years.
