Kyocera Advanced Ceramic Revolution Series 5-inch Micro Serrated Tomato, Utility Knife, Black Blade

This is our third Kyocera Ceramic knife and we love them. Have had one for over four years and the other is over three. All in great condition with only one small chip in the oldest one. Found a great "Black Friday" deal, so got another to give for Christmas. Can't beat a great price on a great product!These knives are extremely sharp and will stay that way if you use them correctly. These knives are NOT to be used on hard items. Such as bones, ice, hard frozen items, or cutting on hard surfaces. They are not made for these types to foods. Use a metal knife for such items.If you use this type of knife correctly, you will be rewarded with many years of sharp cutting. If you neglect them and use incorrectly, you will be unhappy with any ceramic knife.***Also, do not put these ceramic knives in the dishwasher unless they will not be banged around.*** A quick hand washing is all they need. Remember, these are very sharp and will spill blood for the careless. I can attest to this!Pros -1. Super sharp2. Cuts beautifully3. Will last a long time if used correctly4. Easy to cleanCons -1. Can be a little bit expensive if you don't take care of them2. You do have to be more careful with these types of knives (not as forgiving as metal)3. Best not to put in the dishwasher - (handwash)Items were purchased with my own money. No free items received for my review.

Bought one of these in Atlantic City years ago during a cooking class. Loved it!!! Put in the dishwasher ( no-no) and it finally broke down. You cannot use this on hard items!!! But for veggies it’s a must!! So glad to have one again!

So I took a chance on this ceramic fancy pants stuff. And yes this thing is 'sharp' and holds its edge longer than my wustof 51/2. I do competition bbq and have a number of speciality blades this of course cannot replace. But if you only buy one really good knife - an all rounder - consider this one. On the circuit we say "a sharp knife is a safe knife", and I hope you don't get as many scars as I did to learn this and it's value.

This is a really sharp knife and it stays sharp for a long time. The handle is comfortable and the blade shape works well for cutting and slicing. It's also very light - ceramic weighs very little compared to steel.There are a few things that you need to be aware of if you've never used a ceramic knife before.1) The blade is very thin and fragile. Ceramic is brittle compared to steel and you do have to be very careful with it as it's easily nicked. This means you should not use this knife for hard items and keep it away from bones.2) To avoid damaging the blade you need to keep it separate from other utensils. That means it needs to be washed on it's own and stored in a knife block. You do not want to toss this in a sink with other dishes and utensils, nor throw it into a cutlery drawer without a blade guard. You should also handwash. It cleans easily so that's not a problem.3) The wide blade handles well, but food tends to stick to it. Most santuko knives have scallops ground into the sides to help prevent food sticking to the sides of the blade but this blade isn't thick enough to accommodate them. On the plus side the thin blades glides though most material and leaves behind a very clean cut.4) Ceramic is very difficult to sharpen, and because of the very narrow edge angle you cannot use most sharpening tools. Forget about using a steel or most kitchen sharpening devices. You need to use a high quality sharpening tool made specifically to sharpen ceramic knives. That being said, Kyocera offers free sharpening and minor blade repair, you just need to pay for return shipping to California, IIRC. The edge will stay sharp for a lot longer than steel knives, which means it doesn't need to be sharpened very often.It does require some care and feeding compared to steel knives, but if you're willing to put up with a few limitations it's a pleasure to use and it's brutally sharp right out of the box.

Update: I've had this knife for almost a year and the sharpness is still extremely sharp! No dulling and I've never had to send the knife in for sharpening. It still gets used daily in the kitchen, from boneless meat to vegetables and fruit. I love it so much because there's so little maintenance required to keep the blade sharp (just don't cut bones). I'm looking forward to buying a Chef's version of the Kyocera ceramic knives because I love this santoku knife so much!As a big fan of steel knives I was very surprised with the sharpness of this knife. I mainly use this knife for cutting vegetables and fruit. The knife itself is a great addition to any kitchen. I prefer the black blade to the white blade and bought the knife based on aesthetic preferences, but the black blade is made from black zirconium oxide and offers extra durability and also goes through an extra firing process according to Kyocera's website, so that was a plus when purchasing the knife.First off, the knife is very light and the blade is not at all heavy. For people who use steel knives on a daily basis this may take some time getting used to. The knife does an excellent job cutting through vegetables and fruits; however, I don't recommend using it for meat with bones, tough meat, or anything hard. I have used the knife to cut chicken breasts and thighs and cut thin slices of steak just fine. To prevent chipping I hand wash the knife and lay it on a microfiber cloth to dry. Don't put it in the dishwasher or it'll damage the knife.This is a great ceramic knife for anyone looking for their first ceramic or another ceramic for their knife collection. I use the knife on a daily basis in conjunction with my steel knives, and so far my knife hasn't chipped yet and has held its edge well. My only gripe is that the blade is brittle and fragile compared to steel knives.
