With the improvement of living standards, people have higher and higher requirements for the quality of table knives. The variety of goods on the market makes it difficult for consumers to judge the quality of a knife. The senior technical staff of Xiamen Boshun Tableware listed the relevant standards of table knives for consumers' reference.

Knife safety

There must be no sharp edges, notches, burrs, sharp points, edges and corners, breaks, and other parts except the knife teeth must not be palatable.

Knife functionality

The blade is sharp, the teeth are uniform, and the tooth pitch is in accordance with the drawing.The 20N force can be used to cut a piece of 80g A4 paper.

Overall surface of the knife

1.The surface is ordinary cloth wheel light, bright light effect, white light is allowed, and the overall brightness needs to be uniform.

2.The flower shape must be the same as the drawing or confirmed sample, and the protruding part of the handle and neck should not be over polished (flat, flat, and three-dimensional).

3.The pattern is clear and obvious, and slight pattern blur is allowed, and the blurred area cannot be greater than 1CM * CM.

4.The surface allows 2CM * CM area 2-3 places without deep scratches

5.The front side allows 3 0.4MM pits, but the pit distance is not less than 20MM.

6. Corrosion word wheat must not be yellow, white, ghosting, intermittent and fuzzy, and is positive and negative 2.0MM before and after the drawing position, consistent with positive approval.

7.The product should not be over-edged and symmetrical on both sides.

8.The surface of the product must be free of dirt such as fingerprints, oil, water marks, etc., and must be cleaned.

Table knife size

According to the drawings, the allowable deviation of the thickness of the blade is plus or minus 0.2MM, the allowable deviation of the thickness of the shank is plus or minus 0.5MM, and the allowable deviation of the width is plus or minus 0.5MM.

Table knife performance test

1.Corrosion test: 100: 1 salt water is immersed at 60 degrees for 6 hours, and slight rust marks are allowed on the surface. The rust marks must be cleaned by test, and there must be no corrosion dents with a diameter greater than 0.4MM.

2. Strength test: 1. Place the product on the electronic scale platform, the product is 20 degrees from the electronic scale, and apply 60N force to assemble the product.

2. Place it on the tester platform, and let it be subjected to a force of 0.7N / MM or 100N at any point for 10 seconds. Eligibility criteria: No permanent deformation greater than 1MM after the force test.

3.Floor test: The product is freely dropped 20 times from different directions to the hard ground from a height of 1M, and the product has no serious problems such as bursting, fracture, distortion, deformation, looseness (the height is determined by the weight of the product)

4.Hardness test: The hardness of the knife is between 48-52HRC (inspection according to customer requirements).

5.Sharpness test: The blade must be sharp after the blade is reversed. Applying 20N can cut a piece of 8gA4 paper.

6.Material element test: The content of the material elements used must meet the order requirements.
