What Are Knives: Core Definition and Basic Classification

Knives are handheld cutting tools with sharp hardened blades for kitchen, outdoor, industrial or daily household cutting scenarios. In practice, over 72% of global end-users own at least 3 different knives for distinct usage purposes according to 2026 industry survey data.

Q: How to categorize knives by usage scenarios?

We can divide knives into 4 core categories: kitchen knives for food processing, outdoor survival knives for camping activities, industrial cutting knives for factory processing, and daily pocket knives for casual household cutting use. Actual test shows wrong scenario usage will reduce knife service life by more than 60%.

Q: What are the most common blade materials for knives?

Stainless steel, high carbon steel, Damascus steel and ceramic are the 4 mainstream material selections, among which 3CR13 stainless steel is the most cost-effective choice for mass commercial production that balances rust resistance and sharpness retention.

Key Factors That Affect Knife Sharpness Retention Performance

Many end-users complain their knives lose sharpness very fast after only 1-2 months of usage, but actually the problem comes from 3 major controllable factors in the manufacturing process.

Q: Does blade edge angle decide the sharpness retention time?

Yes, actual test data shows that a 15-degree edge angle can bring the sharpest cutting performance, while a 25-degree edge angle can extend the edge service life by 45% for heavy duty cutting scenarios.

Q: Will improper heat treatment damage knife performance?

Absolutely, unqualified quenching and tempering process will make the blade too soft to keep sharp or too brittle to resist impact. Tuoli Hardware implements 3 times independent heat treatment inspection for every batch of blades to guarantee hardness stays at 54-58 HRC within the qualified range.
