About Copper Knife
With its durable hardened stainless steel core, Copper Knife is guaranteed to stay sharp forever, while delivering delicate, paper-thin cuts, and slicing your food prep time in half.
Not only will you be able to easily cut without applying pressure, but the manufacturer claims that Copper Knife’s ergonomic handle and non-stick copper surface will also make it perfect for all your food prep, whether it involves cheese, bread, tomatoes, mushrooms, pineapple, or anything else you enjoy.
You’ve probably noticed that a lot of direct-to-consumer cutlery has entered the marketplace recently, and you want to know how Copper Knife stacks up. Will it deliver more value than your tried and true kitchenware?
Join us as we walk you through the facts.
Is Copper Knife the Right Option For You?
What Type of Knife Is It?
The reality is that most of us have a least a few types of knives in our kitchen drawers. In fact, Consumer Reports recommends you have at least four types on hand, including:
- Chef’s Knife – Typically 8" long and used for chopping, slicing, and dicing.
- Slicer – Longer and thinner than a chef’s knife and often used to cut meat.
- Utility Knife – 4-6" and generally used to cut and slice fruits and veggies.
- Paring Knife – 3-4" and used for peeling and coring.
Of these, Copper Knife appears most similar to a utility knife, so keep this in mind if you’re planning to cut foods for which the knife isn’t intended, like meat and bread.
Stainless Steel Blade Pros & Cons
Furthermore, stainless steel is a widely used material for cutlery, since it tends to retain a sharp edge and resist corrosion. However, stainless steel knives are often more brittle than other materials and can be difficult to sharpen when the time comes.
Pro tip: Unless Copper Knife’s blade is made from ceramic, which doesn’t appear to be the case based on the commercial and website images, stainless steel blades will periodically require sharpening.
In our mind, this casts doubt on the manufacturer’s claim that Copper Knife is guaranteed to stay sharp forever, so remember this point if this claim was your biggest draw to the product.
Chemicals & Cutting
Next, while it’s easy to assume that Copper Knife’s blade is coated in copper based on the name and its coloring, this might not be the case.
In this same vein, we’re not told what makes the blade non-stick. Why’s this important?
Because traditional (i.e. non-ceramic) coatings contain PTFE and PFOA, which, if it flakes off in food or is exposed to too-high temps, may cause unwanted health effects such as flu-like symptoms—even increased risk of cancer.
Finally, see those holes in Copper Knife’s blade? Those are called clefts, which help reduce surface adhesion from sticky foods like cheese. Some knives feature indentations, or even wavy patterns, which accomplish much of the same.
Now, let’s see how these features stack up against other knives in this category.
Copper Knife vs. the Competition
Alright, to quickly recap, Copper Knife is up against other nonstick utility knives with clefts (or indentations), a stainless steel blade, and an ergonomic handle. Is it swimming in competition?
In a word? Yes. Which is something you can see for yourself by searching online for phrases like “non-stick utility knife,” “kitchen knife,” or “slicing knife.” They’re even so popular that you can probably find at least an option or two at any local retailer with a kitchenware section.
The HighYa team has also written about several meaningfully similar options like Aero Knife, Gotham Steel Knives, and Bonzai Blade.
Will all of these options be designed exactly like Copper Knife? Certainly not. But they could deliver many of the same features and much of the same performance for as little as $6.

Outside of Copper Knife, What Are Customers Saying About the Company’s Other Products?
Tekno Products, based out of Rutherford, NJ, has released some decent hits since opening their doors in 2011, including Pillow Pets, Draw Jammies, and Quick Taco.
Compared to many other ASOTV products from third-party companies, Pillow Pets especially seemed to have a highly positive online customer reputation at the time of our research. Customers often referenced solid quality and durability.
Despite this feedback, Tekno Products had an F rating with the Better Business Bureau, based on just three customer complaints (as of 2/14/17). Only one provided details, which referenced difficulty reaching customer support.
Let’s take everything we’ve learned so far and wrap it up.
Will Copper Knife Cut Your Prep Time In Half?
We didn’t test Copper Knife ourselves, but based on its basic design and what we learned from the commercial, it seems reasonable to believe that it could help you slice food better than the dull options currently occupying your kitchen drawers.
But will it really cut your prep time in half? While a sharp knife is always easier to use than a dull one, we’re not sure that this claim is based on much more than marketing hype.
More importantly, though, will Copper Knife deliver solid value? Until the product is released, we know its retail price, and can contact customer support for additional details, this question is impossible to answer.
We also need to know:
- What material is Copper Knife’s blade made from? Does it actually contain copper?
- What about the nonstick material? Does it contain PFOA or PTFE?
