Nutriblade Knives: What You Should Know Before Buying
Nutriblade is a brand that appears in infomercials and as-seen-on-TV marketing channels, selling kitchen knives with the familiar pitch of revolutionary performance at an accessible price. If you've seen the Nutriblade commercials or encountered the knives at a retail display and want a straight evaluation, this guide provides it.
What Is Nutriblade?
Nutriblade is a consumer kitchen knife brand that gained visibility primarily through infomercial and direct-response television marketing. The brand follows the playbook common to as-seen-on-TV products: dramatic demonstrations of cutting performance, before-and-after comparisons with dull knives, and multi-piece offers at a single price.
The brand is associated with ceramic-coated blades that are marketed for non-stick food release and easy cleaning. The ceramic coating is a marketing feature applied to stainless steel blades rather than the zirconia ceramic used in dedicated ceramic knife lines like Kyocera.
The Nutriblade Product
Nutriblade knives feature:
Ceramic-coated stainless steel blades: The blades are standard stainless steel with a ceramic (non-stick) coating applied to the surface. This is similar to the coating on non-stick cookware, designed to prevent food from sticking to the blade during cutting.
Ergonomic handles: Typically soft-grip handles in a comfortable shape.
Multiple configurations: Sets of 3-5 knives in various sizes, often as a bundled set marketed in the infomercial format.
The Ceramic Coating: What It Actually Does
The ceramic coating on Nutriblade knives is not the same as a ceramic knife (like a Kyocera). It's a non-stick coating applied to the surface of a stainless steel blade.
What the coating does: - Reduces food adhesion somewhat during cutting - Makes the blade surface easier to wipe clean - Provides a visual distinction from standard metal blades
What the coating doesn't do: - Improve steel hardness or edge retention - Replace proper knife maintenance - Perform differently than standard stainless in cutting tasks
The coating wears over time, particularly in the dishwasher. Once the coating degrades (which happens faster than infomercials suggest), you're left with a standard stainless steel blade.
Steel Quality Assessment
Nutriblade's steel specification isn't published with precision, which is common for infomercial brands. Based on price tier and construction:
The steel falls in the 420-grade or comparable range, toward the softer end of kitchen knife steel. Hardness is approximately 50-55 HRC, which is below most consumer brands at retail.
This steel: - Sharpens very easily with basic tools - Dulls faster than higher-hardness alternatives - Provides adequate corrosion resistance under normal use - Holds a working edge for light kitchen tasks initially
Performance Reality
Infomercial demonstrations are designed to maximize visual impact. The dramatic comparisons in Nutriblade's marketing compare a fresh Nutriblade against an extremely dull competitor knife, not against a properly maintained competitor knife of similar price.
In real kitchen use:
Initial sharpness: The knives arrive sharp enough for immediate use, the infomercial demonstrations reflect genuine out-of-box sharpness.
Sustained performance: Edge retention under regular home cooking use is limited. The soft steel dulls noticeably faster than mainstream consumer brands like Cuisinart or Farberware.
Coating durability: The ceramic coating wears with repeated dishwasher use. Hand washing significantly extends coating life.
Competitive comparison: A similarly priced mainstream consumer brand knife (Cuisinart Classic, Victorinox paring knife) will hold its edge longer and doesn't depend on a coating for its selling proposition.
Nutriblade vs. Mainstream Alternatives
For the price of a Nutriblade set, you can often purchase individual knives from better-specified brands:
vs. Cuisinart Classic individual knives: Better steel at comparable pricing through retail channels.
vs. Victorinox Fibrox paring knife: The Victorinox paring knife at $15-20 uses better steel and has more reliable quality control than a Nutriblade equivalent.
vs. J.A. Henckels entry-level: Better steel specification and brand accountability.
The infomercial multi-piece pricing creates the appearance of exceptional value, but the individual quality per knife typically underperforms retail alternatives at similar total cost.
Who Buys Nutriblade?
Buyers who match the product: - Consumers who shop primarily through direct-response television and infomercial channels - Anyone attracted specifically to the food-release coating concept - Buyers who want a complete set immediately at a known all-in price - Gift buyers for someone who watches infomercials and would recognize the brand
Buyers who might be better served elsewhere: - Anyone who cooks regularly and wants edge retention beyond a few months - Buyers who can access mainstream retail or Amazon and compare alternatives - Serious home cooks investing in kitchen tools for the long term
Maintenance for Nutriblade Knives
To get the most from the knives:
Hand wash only: The ceramic coating degrades significantly faster in the dishwasher. Hand washing extends both coating and edge life.
Hone regularly: The soft steel needs frequent maintenance. A basic pull-through sharpener keeps the edge functional with minimal effort.
Avoid hard surfaces: Glass, ceramic, and stone cutting surfaces accelerate edge degradation for any knife; they're particularly hard on softer steel like Nutriblade's.
Store carefully: The coating chips when blades contact other metal items. Blade guards or a dedicated slot in a block protects both the coating and the edge.
FAQ
What is the ceramic coating on Nutriblade knives? A non-stick coating applied to the surface of a stainless steel blade, similar to non-stick cookware coating. It reduces food adhesion and makes cleaning easier. It's not the same as a zirconia ceramic knife (like Kyocera).
Are Nutriblade knives any good? They function as kitchen knives for basic tasks. Edge retention is limited due to softer steel; the ceramic coating adds initial appeal but wears over time. They're not competitive with mainstream consumer brands at equivalent price points.
How long does the Nutriblade ceramic coating last? In the dishwasher, the coating can show wear within months of regular use. With hand washing only, it lasts significantly longer but still gradually degrades with use and cleaning.
Where can you buy Nutriblade knives? Originally sold through infomercials and direct response TV. Available through Amazon and some retail channels. Current availability and pricing varies.
Are Nutriblade knives dishwasher safe? Technically yes per their labeling, but hand washing strongly extends both coating life and edge quality. The dishwasher significantly accelerates coating degradation.
What steel does Nutriblade use? Stainless steel without published specification. Based on price tier, it falls in the softer range (approximately 50-55 HRC), adequate for basic kitchen use with frequent maintenance.
