Store listing

Full description
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 6637 alloy names, over 1046 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. Permissions: Storage Access - To import/export bookmarks; Network Access - To synchronize the device with zknives.com central db; Connectivity - Testing connection availability prior to sync attempt; App needs 2mb space on the device, regardless of install location!!! Sorry, there will be no translations to any language. I am one person collecting steel data and coding the app on 3 platforms. I have neither time nor resources to keep constantly translating large database. 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. App is no longer distributed in Russia, due to the excessive amount of complaints and bad ratings, all because I can't translate to Russian, even though app's Russian description did explain why I can't.

What's new

Added support for modern system file picker and bookmark migration from legacy app versions. Added predictive back gesture navigation support on Android 13+ in steel detail view. BugFix: Fixed database synchronization fail with 400 error code. BugFix: Restored missing activity title bar in Steel Browser view on modern Android versions. BugFix: Restored missing title bar and improved legend button placement in Composition Graph view. BugFix: Added missing All selector in Maker Choice View.
