16x3x0.3cm Diy Damascus Steel Billet Bar Sandwich Blanks Knife Making Raw Materi

Product Name: DIY Damascus Steel Knife Blanks

Material: Damascus Steel

Dimensions:
- Length: Approximately 16cm
- Width: Approximately 3cm
- Thickness: Approximately 0.3cm

Note:
- Due to forging and cutting processes, there may be slight variations in size:
- Length and width may have an error of about 1-3mm.
- Thickness may have an error of about 0.1-0.2mm.

Hardness: Approximately HRC58
- Achieved through vacuum deep cooling and heat treatment, balancing sharpness and toughness.

Surface Finish: Smoothly milled and pickled, resulting in a finished product 1.5 times thicker than without flat grinding/pickling (flat grinding removes at least 0.5mm from both sides).

Additional Details:
1. Flat grinding and simple acid cleaning have been performed, but further acid cleaning is recommended after molding/opening.
2. Pattern stickers on both sides may vary slightly in thickness due to segment relationships, and textures on each side may differ.

Pickling Process: Contact customer service for specific instructions.

Water Mixing Ratio: Best ratio is 1:4 (can vary between 1:3 and 1:5 depending on material and acid pickling intensity). Seal well when not in use to prevent dissolution.

Usage:
1. Begin by polishing the rough steel or semi-finished knife product to 600# or above, preferably achieving a semi-mirror state with no visible polishing scratches under light.
2. Submerge in acid pickling solution for approximately 1 minute to observe the effect. For deeper etching, repeat process with shorter durations.
3. Rinse with water and neutralize surface with detergent or detergent solution.
4. Finish with appropriate polishing, buffing, and oiling for maintenance as needed.
