Damascus Steel Knife Blank Billet – Heat Treated DIY Bar 22x3cm

Damascus Steel Knife Blank Billet – DIY Knife Making Raw Material

Craft your next custom blade with this premium Damascus steel knife blank billet. Heat treated using vacuum deep cooling technology, this 22×3×0.3 cm bar delivers the ideal balance of hardness (~HRC 58), sharpness, and toughness — giving you an outstanding foundation for handmade knife projects, whether you're a seasoned bladesmith or an enthusiastic hobbyist.

Each billet has been flat-ground and acid-washed before shipping, giving you a head start over raw, unfinished stock. The pre-treated surface reveals Damascus's iconic layered pattern once you complete your own acid etching at home.

Product Specifications

• Material: High Carbon Damascus Steel
• Dimensions: 22 cm (L) × 3 cm (W) × 0.3 cm (T)
• Hardness: ~HRC 58 (vacuum deep cooling + heat treatment)
• Surface Finish: Pre-flat-ground & acid-washed
• Customizable: Yes – ideal for DIY knife-making projects
• Model: DIY-22
• Made in China

Size Tolerances – Please Note

Due to the forging and cutting process, minor dimensional variances occur in every piece:

• Length & Width tolerance: approximately ±1–3 mm
• Thickness tolerance: approximately ±0.1–0.2 mm

Pre-Treatment Details

• Flat grinding has removed at least 0.5 mm from each side, producing a surface that is 1.5× more finished than an untreated blank.
• Simple acid cleaning has been applied; an additional acid etch is still recommended after you shape and open the blade edge.
• Pattern texture on both sides may vary slightly due to the layered steel segments — this is normal and characteristic of authentic Damascus steel.

Acid Etching Guide (DIY at Home)

1. Polish the billet to 600-grit or higher (a near-mirror finish with no visible sanding scratches under direct light is ideal).
2. Mix acid solution at a 1:4 ratio (acid to water). A range of 1:3 to 1:5 is acceptable depending on your material and desired depth of etch.
3. Submerge the piece for approximately 1 minute per session. Repeat short sessions rather than one long soak for better control.
4. Rinse thoroughly with water, then neutralize the surface with dish soap or detergent.
5. Finish with polishing and a light coat of oil for protection and maintenance.
6. When not in use, seal the acid solution container tightly to prevent evaporation or degradation.

Why Choose Damascus Steel?

Damascus steel is renowned for its beautiful wave-like patterns and exceptional performance. The multi-layer forging process creates a material that holds an edge exceptionally well while maintaining structural flexibility — a perfect canvas for one-of-a-kind custom blades.

Frequently Asked Questions

Q: What is the hardness of this Damascus steel knife blank billet?

A: This Damascus steel billet has been heat treated using vacuum deep cooling technology to achieve approximately HRC 58. This hardness level is carefully balanced to provide both a sharp, durable cutting edge and adequate toughness to resist chipping during shaping and use.

Q: Do I need to acid-etch the billet again after shaping my knife?

A: Yes. While each billet is pre-flat-ground and has had a simple acid wash applied, an additional acid etch is recommended after you have shaped and opened the blade edge. This final etch will fully reveal the stunning layered Damascus pattern on your finished knife.

Q: What tools and materials do I need to complete a DIY knife from this billet?

A: To complete a knife from this blank, you will typically need cutting and shaping tools (angle grinder or belt sander), files, sandpaper (starting at 120-grit up to 600-grit+), an acid etching solution, handle material of your choice (wood, G10, micarta, etc.), handle pins or rivets, and finishing oil. The billet itself is pre-treated, saving you a significant amount of surface preparation time.

Q: Are there size variations between individual billets?

A: Yes, minor size tolerances are expected due to the hand-forging and cutting process. Length and width may vary by approximately 1–3 mm, and thickness by approximately 0.1–0.2 mm. These natural variations are characteristic of hand-forged Damascus steel and do not affect the quality or usability of the billet.
