Copenhagen-based kitchen cutlery brand KUMA Knives has released a free guide on how to properly sharpen kitchen knives at home, as home cooking participation reaches historic levels. The guide warns that dull knives are more dangerous than sharp ones, and that relying on electric knife sharpeners can actually damage blades over time.

Why it matters

With more people cooking at home than ever before, maintaining sharp, safe kitchen knives has become a growing concern. This guide from KUMA Knives aims to educate home cooks on the risks of dull blades and the proper techniques to keep their knives performing at their best for years to come.

The details

According to the guide, dull knives require more cutting force, which increases the likelihood of the knife slipping and causing injury. Poorly cut ingredients also cook unevenly, reducing the quality of the finished meal. The guide cites electric knife sharpeners as a common mistake, as they strip excess metal from the blade with each use, shortening blade life over time. KUMA recommends whetstones as the correct tool for home kitchen knife sharpening, as they provide greater control over the blade angle and remove significantly less material per session.

  • Home cooking participation has reached historic levels, with 54% of consumers cooking more at home than they were five years ago.
  • The global kitchen knife market is projected to grow from $2.11 billion in 2025 to $3.73 billion by 2034, according to Fortune Business Insights.
