База данных ножевых сталей

Уважаемые пользователи, к сожалению, перевод на любой язык не возможен. Кодирование приложения на 3 платформах, сбор данных сталеи, и обработка перекрестных ссылок осуществляется мною одим, в мое свободное время. Приложение является бесплатным, без рекламы. У меня нет не времени, не ресурсов, чтобы постоянно переводить большую базу меняющихся данных. Прошу отнестись с пониманием.
Knife Steel Composition and names cross-reference database.
It is NOT a game, nor a steel history book, nor a knife maker catalog, nor an engineering manual.
If you have relevant information, please share with me and I'll publish it.
Includes popular, exotic and high-end alloys used in knife blades.
Over 6400 alloy names, over 980 compositions. Alloy names for 21 different national standards, proprietary names and their equivalents. Easy composition comparison with bar graph in 3 modes: mass percentage, molar masses and atomic count per 1000 atoms.
Supports Bookmarking of the alloys, including bookmarks export/import, listings by multiple criteria including Standards, Technologies, Makers, Countries, Recently Viewed, Bookmarks, and custom search filters.
Explanation of the alloying elements effects on steel is included, accessible from both, steel detail and graph views.

You can help by reporting missing alloys, and incorrect info. That's a lot more helpful than leaving utterly useless "I didn't find what I wanted" comments, what do you expect me to do anyway, dream up what was it you didn't find? 99% of the times people are mixing up knife brand names with steel names, I can clear that much up if anything else.

Fixes Bookmark export/import for latest Android versions. Bookmarks are exported to the Downloads folder, under its own KnifeSteelChart subfolder.
