Kyocera Ceramics

Micro Serrated Utility Knife

Uniformly Delicious

Summer is here, and with it comes the bounty of fresh fruits and vegetables from your garden or the farmer’s market. To me, there’s nothing better than a tomato picked right off the vine. We use them in salads, sauces, sandwiches and salsa. But we’ve learned the hard way that having a good sharp knife to cut fresh tomatoes is essential, or you’ll wind up with a mutilated, pulpy mess.

Kyocera’s micro serrated utility knife is perfect for tomatoes. It’s lightweight with a razor-sharp ceramic blade (made from zirconium
oxide) that lets you make clean, precise cuts. It won’t rust, and it’s impervious to acids, oils and salts so it doesn’t alter the taste, smell or appearance of food. Besides tomatoes, Kyocera’s serrated knife is great for slicing any foods with a waxy skin and soft center. For a clean, uniform cut every time, nothing beats it.

“You can use it for so many different fruits and vegetables because it doesn’t discolor [the food] and it won’t give an aftertaste,” says Teresa Scenna, an expert in Italian cooking who tested Kyocera’s knife for Daily Grommet. That’s her on the right with her daughter Connie. Those of us who were in the office that day hit the culinary jackpot — we got to enjoy Teresa’s superb insalata caprese. Buon appetito!

    Are ceramic knives really sharper than steel? and...why Kyocera over another ceramic knife?

    What impresses me more than the cutting of the tomatoes, is the Teresa's comments about cutting the basel and the mozzarella. I've a metal tomato knife already but I'm buying this in a minute because it will do the basel and mozzarella so well.

    Hi Rick,

    Thanks for your question! Ceramic knives (or zirconium oxide - the only material in the world harder is diamond) are sharper than steel knives and STAY sharper up to 15x longer. The molecular structure of zirconia can achieve a tighter weave than any metal compound thus creating a sharper edge. Zirconia has greater wear resistance than metal (metal is soft and will roll and dull) so that your edge on your ceramic knives will stay sharper much longer than any metal blade. Ceramics.org (AKA The American Ceramics Society goes into greater length and it's some pretty interesting stuff!) Why Kyocera? Kyocera is the expert in advanced ceramics and has been utilizing and optimizing this amazing material since 1959...the name comes from "Kyoto Ceramics". Kyocera started in the semi-conductor industry, medical and aerospace (to name a few)...we make medical parts that replace parts within the body since ceramic is so wear resistant and the least invasive (non-corrosive) we make Swiss watch parts for the same reason...advanced ceramic is used in Formula One race car brake pads, also used in space shuttles for greater heat retention...and the list goes on! Not all ceramic knives are the same quality...Kyocera knives are made in Kyoto Japan and have higher standards to uphold. The process of heat and pressure is more advanced than other manufacturers. I hope you experience a Kyocera knife for yourself! Thanks again for your question.

    I agree with Nancy....you need to bring Teresa back for more demos. What a sweetheart! One of my favorite Grommet videos ever -- and I've been watching (and buying) from Day 1!

    Teresa was a gem. You could tell that she has sliced many tomatoes and made many insalatas in her life.

    How frequently does this knife need to be sharpened and where do you take it when it does?

    Yes, Isn't Teresa a Love? Nancy and Diana, I will be sure that she gets your comments and requests for her to return. Teresa and her husband, Ennio, have been growing their own tomatoes for years. They can them by the bushel, which is 53 lbs. After the video, she turned to me and asked to buy the Kyocera knife, for she cannot go back to her old knives.

    @Dede - We previously featured the Kyocera 3 inch ceramic paring knife. This question came up then as well and this was Katie's response:

    Ceramic is extremely hard, only diamond is harder. This means there is no give - it won't roll/dull like metal which is why it remains sharp for so much longer. When you eventually need your knives sharpened, you send them to our So Cal location for resharpening. There is a $10 s & h fee up to 2 knives. (You can go to our website for more info.) There is about a 10 day turn around time and you get your knives back as sharp or sharper. Chefs love this service! As far as other care considerations, use your ceramic knives for chopping of vegetables, fruits and boneless meats. Avoid frozen foods or bones. Simply rinse, wipe dry and store in your knife block or drawer. Your Kyocera knife will be sharp and ready for your next prep task.

    Hi Dede, in addition to Katherine's post, sharpening is necessary depending on use...some people it's once a year, others once every 3 years. Since so many customers now have several Kyocera knives, we will sharpen as many Kyocera knives as you own for the same flat $10 Shipping & Handling fee. We also just came out with an Electric Ceramic Knife Sharpener, it's expected to hit the stores in late July. The sharpener, battery operated, has a diamond grinding stone that will refreshen Kyocera ceramic knives back to a super sharp edge.

    PS. I sent Teresa a tomato knife and it should arrive any day now.

    This knife is amazing. True story. Today I'm struggling with three other knives (a tomato kife, a serrated, and a very sharp carving knife) to slice some mozzarella for a caprese salad. Half way through the job, the mail is delivered and there is my knife from Daily Grommet. I take it out and it is amazing how well it cuts. As noted in the video, I'll end up using this knife for everything. I had earlier cut two hamburger rolls (for my son who ate earlier) with a bread knife. I cut the rest of the rolls with the Grommet and, again, it was amazing. My new favorite knife. Another great Grommet.

    I am a guy who LOVES his salads. The best salads are the ones prepared at home of course. I bought the knife last month and my wife thought I was crazy but now both of us are trying to figure out how the heck we did without it for so long.
