Key Quality Control Rules for Knives Production in 2026

All mass-produced knives from Tuoli Hardware need to go through 7 strict QC procedures to avoid defective products. From past 5 years of order cases, our factory’s defective rate is controlled below 0.32%, which is far lower than the industry average level of 2.1% in 2026.

Q: What non-negotiable quality indicators you should check when sourcing knives?

You need to verify 3 core non-negotiable indicators first: no burr on blade edge, no sharp corner on handle that may cut user’s hand, and tight connection between blade and handle with no looseness under 15kg pull force. Any unqualified product with above defects should be picked out directly.

Q: Is there any mandatory safety certification for selling knives in EU and US markets?

For common household knives, FDA food contact material certification is mandatory for kitchen knives sold in North America, and REACH material compliance certification is required for EU market sales. Tuoli Hardware has full certification system to support all document requirements for customs clearance of different regions.

Practical Tips to Extend Knives Service Life

Correct daily maintenance can extend the service life of common knives by more than 60% without extra cost. In practice, we found that 68% of returned damaged knives are caused by improper post-use cleaning instead of inherent material defects.

Q: What is the correct daily maintenance workflow for high-carbon knives?

You need to wipe the blade dry with cotton cloth immediately after using and cleaning, apply a thin layer of edible oil or anti-rust oil on the surface if you will not use it for more than 7 days, and place it in a dry, ventilated place away from corrosive materials.

Q: Can you put different knives in dishwasher directly for cleaning?

We do not recommend this operation. Long-term soaking in alkaline dishwasher detergent and high temperature environment will accelerate the passivation of blade edge and increase the rust risk of alloy steel knives, which will reduce the user experience of your end customers greatly.
