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.

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.

It's great to have an app that gives you the content of the many steel components that are used in knives, old and new. It has most all steels for blades of nearly any you might have, are looking for and are wanting to know more about, with cross references from other countries and Maker's. For me it's priceless to have this app. I personally love it!!!

Extremely useful, has a very wide range of steels and great info about each. Some are extremely detailed, others more brief, but all I've seen so far will give you a decent general idea of what to expect from a steel. Never seen as complete a list of knife steels in one place before, and this even includes multiple brand names for a given type of steel.

This is THE compendium of steels, and a must-have for both new and long-time knife aficionado. It's regularly updated, and for the chemist or amateur smith, the comparative steel composition charts and explanation of elements' roles in alloys is helpful. The reason for 4 vs 5 stars is that there isn't any comparative discussion of steels' characteristics as blades. This app is meant as a tool for knife owners, so info about a relative performance comparing various steels would be useful.

An astonishingly detailed database of knife steels designed and programmed intelligently and flexibly. Gathering this data for us must be a real labor of love. Any data I might wish it had, I don't have the time to gather for him to include - which he likely would. Work like this demands five stars and whatever other support one can offer. Kudos on the simplicity and depth of your interface - it just works. Sincere thanks!

Brilliant app ,incredible amount of data and research has gone into this. Really easy and quick to use and has lots of handy features like the bookmarks ,it's a simple feature but its really helpful, the descriptions are concise and useful, and above all the information the app provides is 100% accurate :-) thank you for all the hard work you've so obviously put into this :-) ive been using this for ages :-) .

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.

I think there were only two instances when I entered the name of the steel and this app didn't have them in the database. Both times I was seeking info on rarely used steels from the 1960's. This app is my go-to reference for all things 'steel.' The descriptions are detailed yet easy to understand. Love it!
