The Rainbow Knife Pro is a kitchen knife with a design inspired by Japanese Santoku knives. Each of these kitchen knives has a stainless steel blade with a handful of oval grooves added for extra precision, and each one is purported to be comfortable to hold because of its ergonomic handle. This knife is meant to be used for cutting a wide variety of food items, from vegetables to fruit to cheeses, and it's unlikely that food will ever stick to its blade.

How It Works

Each of these knives has a rainbow-shaded blade that's about an inch wide, with 10 oval grooves that will enable the blade to cut through virtually any food item more smoothly than other kitchen knives. No matter how many times you use it, the durable stainless steel blade has also been designed to remain ultra-sharp. As a result, even if you use this knife to chop up or slice food more than once a day, you won't find yourself working with a dull knife that gets stuck in the food. The ergonomic handle, made for users to hold comfortably in one hand without fatigue or soreness, will only add to the high level of efficiency you may experience while using your Rainbow Knife Pro.


  • Non-Stick Rainbow Surface

    The surface of each knife's blade is a non-stick one, which means that when you're using it to cut a sticky piece of cheese or a gooey loaf of bread, it won't end up stuck. Instead, it'll glide through any food item you want to cut, and there probably won't be any sticky bits and pieces of food to clean off of it when you're done, either. While the rainbow shading on each knife's blade doesn't do much for its efficiency, it'll simply make it more pleasant to look at as you prepare your food.

  • Stainless Steel Core

    The core of each knife, including the part that's underneath the black handle, is made of stainless steel. Stainless steel is known for being a durable material, so that means it's unlikely that the blade will ever crack on its own or become separated from its handle. The potential for accidents like this can make a kitchen knife unsafe to use, which is one major reason why you may choose the Rainbow Knife Pro over a knife made of lower-quality materials.

  • Moderately Long

    Some kitchen knives have short and stubby blades that won't extend across a larger item like a whole loaf of bread or an entire pineapple, but that's not the case with this knife. Each knife's blade is a few inches long, and if you're cutting something like tomatoes or potatoes, you may actually be able to fit two of them underneath the blade at once. (However, you may find that your cuts are more precise if you cut one thing at a time.).

Positive Points

  • Doesn't Need Sharpening

    Since you can expect your Rainbow Knife Pro to remain sharp throughout its lifetime, which could be several years or even more than a decade long, you won't have to get it sharpened regularly. If you use this knife for all your food-cutting tasks, you'll no longer have to keep a sharpening tool in your kitchen or visit a professional knife-sharpening establishment on a regular basis. This knife will only become dull if you use it for non-food items that it's not meant to cut, such as wood, metal or rubber.

  • Can Be Used In Restaurants

    This knife is ideal for use at home in your kitchen, but it's also effective enough to be used by restaurant owners. If you run a restaurant and invest in a few of these to be used in its kitchen, you may end up getting your food preparation work done in half the time you normally take. Plus, your staff may be impressed by the unique rainbow-colored blades.

Negative Points

  • No Case For Blade

    Some ultra-sharp knives come with a case that you can slide over the sharp blade of the knife when you're not using it. No such case comes with the Rainbow Knife Pro, though, so you'll need to fashion one yourself or store your knife somewhere where the blade is tucked away instead of sticking out. If you were to leave this knife's blade lying bare in your kitchen, someone might accidentally cut their hand on the blade, which could draw a lot of blood.

  • May Not Be Dishwasher Safe

    Whether this kitchen knife is dishwasher safe isn't specified, making it safe to assume that you may need to wash yours by hand. Doing so will require great care, and perhaps a pair of gloves made of rubber or fabric, or else you could cut your fingers on the blade's sharp edge. Even though it may not look like there's any food residue left behind on your knife, you should always wash it after each use, to get rid of any invisible bacteria that might be present.


  • Only For Adults

    The Rainbow Knife Pro is a knife that only adults should be using, as children likely won't yet have the hand-eye coordination required to control the knife, and could injure themselves. When it comes to teenagers, take into account their skills and use your best judgment to decide whether or not they'll be able to control a large, super-sharp blade without risking injury. Any teen should be supervised at all times while they use this knife.
