The Water Blade Knife is a chef's knife that's purported to be able to keep itself sharp by using only the power of water. As a result, it follows that every time you wash it, it may end up being sharpened for you. This knife has been crafted to be powerful enough to slice through a hard pineapple or a frozen cut of meat, but gentle enough to thinly slice vegetables like potatoes and tomatoes evenly.

How It Works

Each Water Blade Knife is made of high-quality carbon steel that will potentially last you for years before starting to break down. This material also naturally remains sharp, even if you run the risk of dulling it by using it on a hard substance like wood, cement or plastic. If you ever notice that your knife is a bit duller than before, its sharpness can be reactivated through contact with water. Since it can be assumed that most people wash their kitchen knives frequently, in order to avoid food poisoning, the sharpness of your knife's blade may end up receiving a tune-up every single day.


  • For Commercial or Home Use

    This knife is a great one to use when you're making dinner for yourself or your family in the kitchen. However, it's also efficient enough to be used in a commercial restaurant setting, in which you might need to slice or chop dozens of food items in minutes. If you run a restaurant, you might want to obtain several of these knives and speed up the food preparation process even more than you'd be able to by using just one.

  • Recessed Handle

    The handle on each Water Blade Knife has a recessed design, which makes it more comfortable for a user to grip than if it were perfectly straight. This also gives a user a lot of control over the blade, so they don't end up making inaccurate cuts that might ruin the look of their food.

  • Full Tang

    Each of these knives has a full tang, which means that the blade is at least as long as the handle. That means you'll have a lot of room on your blade for cutting wide food items without having to put your fingers extremely close to where you're slicing. This may help you avoid finger injuries that might otherwise occur, especially if you prefer to cut your food without wearing any sort of protective hand covering.

  • Comes With Sharpening Sleeve

    Although, as mentioned, each Water Blade Knife can be kept sharp due to its blade's contact with water, each one comes with a sharpening sleeve, too. Not only can you use this sleeve to store your knife so its blade isn't exposed, but the built-in Bavarian sharpener inside will also sharpen the knife for you each time you slip it inside. When you pull it out, regardless of what food item you need to cut, you'll consistently have a razor-sharp knife to work with.

Positive Points

  • Will Cut Tough Items

    Not all knives will cut super-hard foods like pineapple or pumpkin, so without the Water Blade, you might find yourself not adding these items to dishes when you'd prefer to include them. Fortunately, this type of knife will cut through virtually any type of food without severely dulling itself, so you'll be able to cut up and use whatever ingredients you want to. Even if you'd prefer not to eat pumpkin, you might find one of these knives useful when you want to carve a face on one for Halloween.

  • Reduces Need For Many Knives

    If you don't have a multi-purpose knife like the Water Blade, you might have a bunch of knives in your kitchen that you use to cut different things instead. This razor-sharp knife will make both powerful and delicate cuts, though, so if you're looking to save space, you may be able to get rid of some other knives and just use this one. Then you won't have to fumble around in a drawer while you're looking for the appropriate knife, especially since this one's sharpening sleeve will enable you to identify it quite quickly.

Negative Points

  • A Risk For Inexperienced Cooks

    Working with an extremely sharp knife such as this one is a great idea if you're an experienced cook who knows how to hold a knife safely and correctly. Unfortunately, there's also a huge potential for injury with this knife, if you're not experienced with food preparation and don't seek another person's help. Inexperienced cooks will need to take great care to point their knife's blade away from themselves and keep their fingers away from it. Otherwise, it could do a lot more damage to a bare hand than a duller knife would ever be able to.


  • Keep Away From Kids

    On a related note, the Water Blade Knife must be stored out of the reach of children, even while it's in its sharpening sleeve. Kids who haven't yet reached their teenage years should never use it, because of its ultra-sharp blade, and teenagers should be watched very closely if they choose to work with one.
