Granitestone Nutriblade 12-Piece Knife Set: Complete Review

The Granitestone Nutriblade 12-piece knife set combines Granitestone's granite-texture non-stick branding with Nutriblade's coated knife system. If you've seen the ads and are trying to decide whether the set delivers, here's an honest assessment.

What's in the 12-Piece Set

A standard Granitestone Nutriblade 12-piece configuration typically includes:

  • 8-inch chef's knife
  • 7-inch santoku knife
  • 6-inch utility knife
  • 5-inch serrated utility knife
  • 3.5-inch paring knife
  • 4 steak knives (4.5-inch)
  • Kitchen shears
  • Knife block with granite-look exterior

The four steak knives account for a third of the piece count. The main cooking knives are the chef's knife, santoku, two utility knives, and paring knife, which cover the standard kitchen tasks well enough for daily home cooking.

The Granite-Texture Blade Coating

The defining feature of this set is the granite-speckled non-stick coating on the blades. This is the same approach Granitestone uses in their cookware: a textured non-stick surface that reduces sticking and is visually distinctive.

For kitchen knives specifically, the coating provides modest food-release benefits. Soft foods like bananas, avocado, and soft cheese stick less to a textured non-stick surface than to a polished stainless blade. The practical benefit for most cutting tasks is minor, but it's real.

As with all blade coatings, this one wears at the edge over time. Sharpening removes the coating at the cutting zone. The visual pattern further back on the blade persists longer, but the functional non-stick benefit at the actual cutting edge diminishes with use.

Steel and Sharpness

The steel in the Granitestone Nutriblade set is high-carbon stainless without a published Rockwell hardness rating. Based on performance reports and pricing, it's likely in the 54-56 HRC range.

Out of the box, the edges are sharp enough for immediate use on tomatoes, herbs, and proteins. The factory edge handles daily kitchen tasks adequately during the first few months.

Edge retention is moderate. Regular honing extends the time between sharpenings, but expect the edges to need attention every 6-8 weeks with consistent home cooking use.

The Knife Block

The block in this set features a granite-look exterior that matches the blade aesthetic. It's attractive and coordinates well with the overall visual identity of the product. Construction is typically composite material with a decorative surface treatment.

The block uses standard slotted design. One note: insert knives with the cutting edge up rather than down to prevent the edge from contacting the wood slot during storage.

Performance by Knife

Chef's knife: Handles everyday prep adequately. The granite coating is visible and the blade releases soft foods cleanly. The weight and balance are functional for home use.

Santoku: Lighter than the chef's knife, good for vegetable work. The hollow-edge dimples (if present in this configuration) add to food release.

Utility knives: The serrated utility handles tomatoes and sandwiches well. The plain utility works for mid-size cutting tasks.

Paring knife: Small, comfortable for detail work and peeling.

Steak knives: The four included steak knives use micro-serrations. They cut cooked protein reasonably well.

Who This Set Is For

Good fit: - Buyers who want the granite aesthetic to match other Granitestone cookware - Home cooks who want non-stick coating convenience - Anyone looking for a complete set at a moderate price with visual appeal

Less ideal for: - Cooks who want premium edge retention and long-term performance - Anyone who will cook daily and expects the sharpness to last months without attention - Serious home cooks comparing cost-per-performance against quality German or Japanese brands

Maintenance

For best results: - Hand wash and dry immediately. Dishwashers degrade both the blade edge and the coating faster. - Hone with a standard honing steel before cooking sessions. - Sharpen with a pull-through sharpener every 6-8 weeks with regular use. - Don't use on hard bones or frozen food. - Avoid glass, stone, and ceramic cutting surfaces.

The steak knives (micro-serrated) don't require active sharpening in normal use.

FAQ

Is the granite coating on the blades real granite? No. The granite-look finish is a non-stick coating with mineral particles that create the visual texture, not actual granite. The same approach Granitestone uses in their non-stick cookware.

How does this compare to a standard Nutriblade set? The Granitestone version adds the granite aesthetic and Granitestone branding. The underlying knife construction and steel are similar to standard Nutriblade configurations. The differences are visual rather than performance-based.

Does the coating make a meaningful difference in cooking? For specific tasks (soft, sticky foods), yes, modestly. For most everyday cutting tasks, the difference is minor and diminishes over time as the coating wears at the edge.

Are the steak knives worth using? Yes, they're functional. The micro-serrations cut cooked protein adequately and require essentially no maintenance. For households that regularly eat steak at the table, having four steak knives included is practical value.

Conclusion

The Granitestone Nutriblade 12-piece knife set is a visually cohesive, mid-range kitchen knife collection that delivers what its marketing describes: non-stick coated blades with a granite texture, a complete piece count for everyday cooking, and an attractive block. The performance is adequate for home cooking tasks and the steak knives add practical value. For buyers who want premium edge retention or are comparing purely on cutting performance, established brands at similar price points offer better outcomes.
