Great way to approximate the Rockwell hardness of my tools and blades.
These files are just what I was looking for. I even received a bag of lollies from Aus Maker. Excellent service.
Description
Damascus Raindrop Pattern Stainless Steel Bar Pre Hardened
Damascus or pattern welded steel consists of two or more types of steel layered and heated up to forge welding temperatures and then squished together causing the atoms to stick together forming a singular bar of steel. Pre hardened to ~60HRC
In this bar of steel we have stainless steel layered steel as a cladding and a core steel (a VG10 steel equivalent 10Cr15MoV) The core steel is ~0.8mm of hardened steel in the centre.
Process for working
- Cut out the steel to your blade design
- Grind in bevels
- Hand sand the blade
- Etch in ferric chloride & Hydrochloric acid.
- Wash thoroughly with water to neutralise the acid
