Granitestone 6-Piece Nutriblade Knife Set: What to Know

The Granitestone 6-Piece Nutriblade knife set is a collaboration product between two consumer kitchen brands: Granitestone, known for their granite-look non-stick cookware, and Nutriblade, known for non-stick coated kitchen knives. The resulting set combines the non-stick coating approach with Granitestone's visual branding.

If you've seen this set and want to know whether it's worth buying, here's an honest breakdown.

What's in the 6-Piece Set

The standard Granitestone Nutriblade 6-piece set typically includes:

  • 8-inch chef's knife
  • 7-inch santoku knife
  • 5-inch utility knife
  • 3.5-inch paring knife
  • Bread knife (varies by configuration)
  • Knife block or storage case

This is a practical selection for everyday cooking: the chef's knife and paring knife cover most tasks, the santoku gives you a lighter option for vegetable work, and the utility knife fills the mid-size role.

The Granite-Look Coating

The distinctive feature of the Granitestone collaboration is the granite-speckled appearance of the blade. This is a non-stick coating with granite particle texture embedded in or on the surface, the same visual approach Granitestone uses in their cookware line.

Does the Coating Help with Cooking?

Like other non-stick blade coatings, this one reduces surface friction. Food, particularly soft sticky items, releases from the blade more easily than from an uncoated blade. This is a genuine (if modest) functional benefit.

The texture from the granite particles may provide slightly more food-release benefit than a purely smooth coating, though the practical difference in everyday kitchen use is minor.

Coating Durability

Non-stick coatings on knife blades wear off over time. The granite-textured coating is harder than smooth polymer coatings, but the edge area, where the blade contacts food most, is the first to show wear. Sharpening removes the coating at the edge.

This is a consistent characteristic of all coated knives: the coating gradually disappears from the functional cutting area over months to years of use. Plan on the non-stick benefit being most noticeable during the first year of ownership.

The Steel

Granitestone and Nutriblade don't prominently publish the steel alloy or Rockwell hardness for this set. This is a common pattern for consumer-facing knife brands that lead with aesthetics and features rather than metallurgical specs.

Based on the price point and construction, the steel is likely mid-range stainless in the 54-57 HRC range. This is functional for home cooking: adequate edge retention for moderate use, easy to resharpen, and compatible with the integrated coating approach.

At this hardness: - Hone regularly (weekly or before cooking sessions) - Sharpen every few months with a pull-through sharpener - Don't expect the long-between-sharpenings performance of harder Japanese steel

Handle Design

The handles in this set are typically ergonomic synthetic material in black or dark tones, complementing the granite-look blade aesthetic. The handles prioritize comfortable use for a general audience: not specialized for any one grip style, but adequate for both wrap and pinch grips.

Full-tang construction on the chef's knife is standard. The metal runs the full length of the handle, visible as rivets, providing balance and durability.

Granitestone Nutriblade vs Plain Nutriblade

The Granitestone version of the Nutriblade set adds the granite-texture visual look and some marketing around the combined brand. The underlying knife construction and steel are similar to standard Nutriblade sets. If you specifically want the granite aesthetic to match Granitestone cookware, this is the product. If you're evaluating purely on knife performance, the visual difference doesn't affect cutting.

Who This Set Is For

The Granitestone 6-piece Nutriblade set is appropriate for:

  • Buyers who own Granitestone cookware and want matching visual aesthetics
  • Home cooks who want non-stick blade coatings and find the granite look appealing
  • Anyone who wants a complete knife set at a moderate price without specific performance expectations

The Alternatives Worth Considering

At comparable prices:

Victorinox Fibrox 6-piece block set: Better edge performance, no coating gimmick, proven steel. Less visually distinctive.

Cuisinart block sets: Similar pricing, established brand, comparable steel quality. Widely available customer service.

Individual Victorinox chef's knife + paring knife: Two excellent knives that outperform an entire Granitestone Nutriblade set for the actual tasks those two knives handle.

Care and Maintenance

For best results with this set: - Hand wash only. The granite coating and knife edge both last longer without dishwasher use. - Dry immediately before returning to the block. - Sharpen with a pull-through sharpener when the edge stops responding to honing. The coating will wear at the edge; this is normal. - Use wooden or plastic cutting boards exclusively. - Don't use on hard bones or frozen food, which stresses the edge and the coating disproportionately.

FAQ

Is the granite coating on these knives real granite? No. "Granite" refers to the visual appearance of the coating, similar to how Granitestone's cookware has a granite-look non-stick surface. It's a polymer coating with mineral or metallic particles that create the visual effect.

Does the non-stick coating affect how sharp the knife is? No. Sharpness is determined by the steel and edge geometry, not the surface coating. The coating reduces friction between blade and food but doesn't change how sharp the edge is.

How long does the non-stick coating last? Visible coating wear typically begins at the edge area within the first year of regular use. The coating further back on the blade lasts longer. Avoid dishwasher use and don't sharpen more than necessary to extend the coating's life.

Is this set worth buying over a standard (uncoated) set? If the non-stick coating and granite aesthetic have specific appeal to you, the answer can be yes. For pure cutting performance at the same price, uncoated knives with better-specified steel offer more value.

Conclusion

The Granitestone 6-piece Nutriblade knife set is a visually distinctive product that delivers functional kitchen knife coverage with the added benefit of non-stick coating during the early period of ownership. The granite aesthetic is well-executed and matches Granitestone cookware for buyers who care about visual consistency. For serious cooking performance, the money buys better per-knife quality from established brands with published steel specifications.
