About this app

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 6600 alloy names, over 1035 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.

Outstanding app and a fantastic resource for the knife community. FEATURE REQUESTS: (1) Change the blue in the chart to a lighter color that would be easier to see when a device is set to Dark Mode. (2) Disable swipe in chart mode (or make it much less sensitive?). I use Mass% almost exclusively in the chart but I find myself accidentally swiping when I touch a column to see percentages.

Thanks for the feedback! As it happened, I had to push a new release. I addressed both of your requests. Blue is lighter and added logic to reduce swipe sensitivity. Let me know how it goes. Get the latest once its available in your marketplace 3.99.3

Thank you for this app!!!! The information in this app is exactly what I have been looking for. The notes are great. The graphs are great. The only issue I have is that the dark mode affects my eyes negatively. I find that I can't look at the screen for too long without it bothering my eyes. Is there an option to change it that I am missing, or is there any way a light mode version can be added???? I would like to use it more if I could. Thanks.

Sorry, there's no option, not right now. Hardness data is too big of a change along with other things in it. I could add light mode. Interesting, for me light screens are far more eye straining. Anyway, I'll add light mode for the future release.

Over the last couple years I have developed a hobby in collecting knives. Utilizing the extensive information provided here, I am able to learn the composition and history of the steel used in each of my knives. One critique would be that much of the information is redundant. Another is that much of the language is over my head and there are often anywhere from two to ten definitions for each steel, whose titles are generally differentiated by a set of quotations or a semi-colin.

Hiya, thanks for the feedback. Can you please email me? I wanna understand your critique better. As for the steel definitions, it's how it is, each standard spec is produced by dozens of makers, and you can encounter a knife using any of those names, so I have to list them all.
