Strain Removal

Strain Removal” refers to the process of removing distortion and strain from the blade caused by forging and heat treatment in the manufacturing process of knives and blades. This is an important operation performed to ensure the accurate shape and stability of blades during the manufacturing process.

The main features and purposes of strain removal are explained below:

  1. Distortion caused by forging and heat treatment: In the manufacture of knives, distortion can occur in the blade during the forging and heat treatment processes. For example, distortion occurs when one part gets hotter than the other during forging and shrinks during cooling.
  2. Ensure blade shape accuracy: Knives must have an accurate blade shape. Strain removal is important to remove any remaining distortion, which can make the blade shape unstable and adversely affect usability and sharpness.
  3. Manual Adjustment: Strain removal is usually done by hand. The craftsman may correct the distortion of the blade visually or by feel. This ensures a high quality finish.
  4. Toward the final finish: Strain removal is also a part of the knife manufacturing process that prepares the knife for the final finish. Ensuring an accurate shape allows subsequent polishing and finishing operations to be carried out more effectively.

Strain removal is an essential process for improving the quality and performance of knives, and requires the skill and experience of the craftsman.
