Key Specifications

• Material: High Carbon Damascus Steel (VG10 Sandwich Core)
• Dimensions: 40cm (L) × 5cm (W) × 0.5cm (T)
• Hardness: ~58 HRC (lower hardness on outer layers for enhanced toughness)
• Surface Finish: Pre-flat-ground & acid-pickled (semi-finished)
• Package: 1 piece
• Model: DIY-40
• Made in: Mainland China

Why Choose This Damascus Billet?

• ✅ Vacuum deep-cooling & heat treated for consistent, reliable hardness throughout
• ✅ Pre-flat-ground — both sides milled smooth, saving you significant shaping time (at least 0.5mm removed per side for a true flat grind)
• ✅ Acid-pickled surface reveals stunning Damascus layered patterns; additional pickling after shaping will deepen the visual contrast
• ✅ Suitable for fixed blade and folding knife projects — kitchen knives, hunting knives, custom collectors' pieces, and more
• ✅ Customisable — the blank format gives you full creative freedom over profile, grind, handle, and finish

Size Tolerances

Due to the forging and cutting process, minor dimensional variances are normal: ±1–3mm on length and width; ±0.1–0.2mm on thickness. Pattern sticker intensity on each face may also vary slightly between sides.

Acid Pickling Guide

1. Polish the blank to 600-grit or higher (semi-mirror finish recommended — no visible scratching when viewed in light).
2. Submerge in acid pickling solution for approximately 1 minute per pass. Repeat in short sessions to deepen the Damascus pattern.
3. Rinse thoroughly with water after each pass.
4. Neutralise surface acid with dish soap or detergent, then rinse again.
5. Finish with light polishing and a coat of protective oil.
6. Best water-to-acid ratio: 1:4 (acceptable range 1:3 to 1:5, depending on steel condition and desired depth). Seal the solution tightly when not in use to prevent deterioration.

Ideal For

• Hobbyist and professional bladesmiths

Frequently Asked Questions

Q: What steel is used in this Damascus knife billet and what hardness should I expect?

A: This knife billet uses a high carbon Damascus steel construction with a VG10 sandwich core. After vacuum deep-cooling and heat treatment, the billet reaches approximately 58 HRC. The outer layers are intentionally kept at slightly lower hardness to maximise toughness while the core retains a keen, lasting edge.

Q: Is the billet ready to grind and shape, or does it need additional preparation?

A: The billet arrives pre-flat-ground and acid-pickled, so it is in a semi-finished state — ahead of an untreated raw bar. You can proceed directly to profiling, grinding your blade geometry, and further acid pickling after shaping to bring out the full Damascus pattern. Note that at least 0.5mm per side has already been removed during the flat-grinding step.

Q: Can this billet be used for both fixed-blade and folding knife projects?

A: Yes. At 40cm × 5cm × 0.5cm, this billet offers enough material for a wide range of fixed blade and folding knife designs, including chef's knives, hunting knives, and custom EDC folders. Its dimensions and stock thickness make it versatile for most DIY knife-making projects.

Q: What tolerances should I account for when planning my knife design?

A: Allow for manufacturing tolerances of ±1–3mm on length and width and ±0.1–0.2mm on thickness. Factor these into your design layout before cutting your profile to ensure your finished blade dimensions are accurate.
