Nutriblade.com: What Granitestone's Knife Brand Is About
Nutriblade is Granitestone's kitchen knife brand, and if you've landed on nutriblade.com or seen these knives advertised, you're looking at an infomercial-adjacent brand that markets kitchen knives with a focus on non-stick coatings and a set-completion model. Here's the honest breakdown.
What Nutriblade.com Sells
Nutriblade.com is the dedicated storefront for the Nutriblade knife line from Granitestone, known primarily for their granite-coated cookware. The knife line follows a similar approach: kitchen knives with a non-stick titanium coating that's marketed as a solution to sticking food and difficult cutting.
The brand targets home cooks who respond to infomercial-style marketing: demonstrations of food sliding off the blade, dramatic before-and-after cuts, and sets that can be expanded with additional pieces.
The Nutriblade 6 Piece Nutriblade Knife Set
The flagship Nutriblade offering is their 6 piece set, which you can find at major retail stores (Walmart, Bed Bath & Beyond historically, Amazon) as well as the Nutriblade website directly. The set typically includes:
- Chef's knife
- Bread knife
- Utility knife
- Paring knife
- Honing rod
- Block or storage solution
Sometimes configured as 5 piece with a slicing knife in place of one of the above.
The Titanium Non-Stick Coating: What It Actually Does
The marketing claim is that Nutriblade's titanium-infused non-stick coating prevents food from sticking to the blade and makes cutting easier. This has some basis in reality, but the claim requires unpacking.
What the coating does: It reduces the surface friction between blade and food, which means thin slices of soft items (cheese, certain vegetables) are less likely to stick. This is a real benefit for specific tasks.
What it doesn't do: It doesn't make the underlying steel sharper or improve edge retention. The coating is surface-level and doesn't affect the cutting edge itself.
The limitation over time: Non-stick coatings on knife blades wear. The coating around the cutting edge degrades with sharpening (and you can't sharpen coated blades with standard tools without affecting the coating). Once the edge dulls, you're left with a coated blade that you can't maintain properly without damaging the coating.
Steel Quality in Nutriblade Knives
Nutriblade doesn't prominently specify their steel grade or hardness in most product listings. At the price point and category they occupy, the steel is likely around 52-55 HRC, which is on the softer end of functional stainless.
This is the primary limitation of budget-to-mid infomercial kitchen knives: the marketing emphasizes the coating and the demonstration appeal, while the underlying steel is average at best.
Who Actually Benefits from Nutriblade Knives
The Nutriblade knife set makes sense for a specific buyer: someone who prioritizes easy food release over ultimate sharpness, cooks lighter tasks (doesn't need to break down whole chickens or handle thick root vegetables), and values the infomercial-style purchase experience with TV-advertised brand name recognition.
It's less suitable for: - Buyers who sharpen their knives regularly (coating conflicts with sharpening) - Cooks who handle hard foods or need a knife that stays sharp for years - Anyone who wants to grow as a cook and learn proper knife maintenance

The Buying Experience: Website vs. Retail
Nutriblade.com sells direct with options to add additional pieces. The website experience includes upsell opportunities (adding steak knives, specialty knives, accessories). The retail experience (Amazon, Walmart) is more straightforward.
Retail pricing is often comparable to or better than the website's advertised price after applying website shipping and handling costs. Compare the full landed cost before choosing where to buy.
Caring for Non-Stick Coated Knives
Non-stick coated kitchen knives require specific care:
- Hand wash only: Dishwashers degrade non-stick coatings faster than any other care issue. This is non-negotiable.
- Avoid abrasive sponges: Standard dishwashing scrubbers scratch and degrade the coating over time. Use soft cloths or sponges.
- Don't sharpen with standard tools: Whetstones, pull-through sharpeners, and honing rods can damage the non-stick coating. The blade can be honed on ceramic very gently, but aggressive sharpening removes the coating.
- Expect coating wear: Non-stick knife coatings degrade over 2-5 years of regular use. Plan for eventual replacement.
Frequently Asked Questions
Is Nutriblade the same as Granitestone? Nutriblade is Granitestone's dedicated knife brand. Same parent company, same marketing approach, specifically applied to cutlery.
Can Nutriblade knives be sharpened? Traditional sharpening methods will damage the non-stick coating. The knives can be lightly touched up with a ceramic honing rod, but aggressive resharpening isn't compatible with maintaining the coating. This is a significant limitation compared to uncoated knives.
How does Nutriblade compare to Victorinox or Wusthof? Steel quality and edge retention don't compare favorably. Victorinox and Wusthof offer better steel, better sharpening potential, and longer service life. Nutriblade's competitive advantage is the non-stick coating and the infomercial marketing appeal, not cutting performance.
Where is the best place to buy Nutriblade knives? Amazon or major retailers often offer competitive pricing without the website's add-on pressure and handling fees. Verify current pricing across channels before ordering from nutriblade.com directly.
The Bottom Line
Nutriblade knives from Granitestone offer non-stick coated blades at accessible prices with infomercial-style marketing. The coating provides real but limited benefits for specific tasks, while the underlying steel is average and incompatible with traditional maintenance techniques. For buyers who want easy food release and don't plan to maintain their knives intensively, Nutriblade is a functional if replaceable option. For buyers who want knives that improve with care and last for years, the same money spent on Victorinox or Mercer delivers dramatically better value.
