Finally I did it :) For Android smartphones, 1.6 and higher, the chart or database application is out. It's a snapshot of October 5, 2010, later I'll add online synchronization. Most of the online functionality from the Interactive Knife Steel Composition chart is there, including comparison graphs.

While I was getting new site up broke reviews. Seemingly unrelated code change, somewhere else... While at it, also found and fixed broken image links in Shun DM0718 Classic Santoku Review, and Furi Cleaver Chopper Review.

Visitor gave heads up on that. Thanks! New alloy - Aichi ZA-18 steel. Apparently created to compete and outperform Takefu VG-10 steel. Slightly more Carbon, Chrome, Cobalt and Molybdenum. One thing I am not clear is the Vanadium content. VG-10 contains 0.10% to 0.30% which besides refining grain can affect abrasive wear resistance, but in those amounts probably not so much. I'm trying ot get more precise information.

My first knife from William Henry, and the deciding factor was the Hitachi ZDP-189 steel. Classic gentleman's folder, very high quality and craftsmanship, hi-tech materials from blade to handle, and to complement all that, super duper blade steel. Details in the review. Very positive results and I am very happy with the knife. ZDP-189 is not brittle, and that was covered in Super Hard vs. Soft Edges article.

Added Daido DEX80 PM high speed tool steel composition. Similar to Hitachi HAP72 high speed tool steel.

Added Hitachi proprietary HAP 10 high speed tool steel composition. There are several other HAP series steels made by Hitachi. All high speed tool steels, som eproprietary, others similar to AISI M series high speed steels, the difference with HAP 10 is that it doens't contain Cobalt unlike its other HAP brothers.
