Ninja StaySharp 6-Piece Knife Block Set K32006UK
Our Verdict
A self-sharpening 6-piece knife block set from Ninja with built-in integrated sharpeners in every block slot.
Why it's number one: Leads on handling and storage with a block that sharpens every blade as it is drawn, second on sharpness with forged German steel; no critic review found; 4.8-star Amazon rating from 2,866 owners, the largest base here.
Ninja's StaySharp set is a genuinely clever innovation: each slot in the knife block has an integrated sharpener built in, so your blades get a micro-sharpening every single time you put them away or take them out. The result is knives that stay sharper for longer with zero extra effort - ideal for anyone who forgets to hone regularly. With over 2,800 Amazon reviews at a 4.8-star rating, it's one of the most beloved knife sets you can buy right now. The high-carbon German stainless steel blades are razor-sharp from day one. The catch is the seller: this set comes from Amazon UK rather than local stock, so delivery takes longer than the Australian-stocked sets here and returns go back overseas.
Owners is the 4.8★ Amazon AU rating from 2,868 reviews, weighted toward the category average when there are few. Fewer than two published reviews of this exact model, so the owner rating carries that weight too. Tick marks show the category average.
How we scored it
