Simple, useful, thank you! Only gripe: maybe remove the large ingredient/chemical (?) list for each steel at the forefront, and maybe move it all elsewhere via a link, etc. Most users id imagine are not chemists or steel workers. Maybe have facts listed for knife collectors, and pics of the steel in different knives etc ### 5/5 — Absolutely awesome for anyone interested in knife steels. *2024-03-25, version 1.93* Fantastic for anyone who is just beginning to learn about knife steels and their properties; right through to blade steel engineering and metallurgy. I have been learning about knife steel properties, blade metallurgy and blade forging as a hobby/interest for a few years now; and thanks to the legendary Knife Steel Nerd himself (Dr Larrin Thomas) I’ve learned enough metallurgy to get a good idea of potential blade steel properties through just learning their composition. So every time I hear about a blade steel I’ve always had to search my browser, writing the steel’s name and “steel composition” (so much so I made a keyboard shortcut). But then I usually have to search through many rubbish advertising websites (that Google and Bing always put first through ad payments) with rubbish knife steel articles written by 2nd/3rd world marketing people with terrible English, who just copy and poorly rewrite all their information from other sources, adding their own poorly written flair to pad out the rubbish articles as much as possible, often turning the few remaining correct details they had into rubbish. For whatever backwards advertising reasons Bing and Google algorithms have begun putting them at the top of every search, usually covering at least the first page for me now. So in a hurry it takes some time to find the information that may or may not even be correct. Since I found out the ZKnives website I’ve been looking for results in that, but it’s never on the first search results page, and I can never find it in my favourites/bookmarks etc. and I’m usually in a hurry (but for the record the ZKnives website is also AMAZING although can be a little difficult to navigate on my phone). So I heard about and downloaded this app a while ago but forgot about it. I just used it now to compare the material compositions of several different blade steels (both separately and together), and I was done in seconds, user friendly as you like with zero rubbish. This may be my new favourite app, and I sincerely thank the legends who created it! ### 5/5 — Useful! *2024-03-12, version 1.93* This app is such a great idea! I am always searching online about knife steels, and the fact that this app aggregates all this information in one place is excellent. The app is well-built and coded decently. The focus is definitely on the info, though. ### 5/5 — Great resource *2024-01-12, version 1.93* This is comprehensive and has certainly changes the way I buy and care for knives. Top notch! ### 5/5 — Nothing better or simpler *2023-12-31, version 1.93* If you like knives in any way, this is the perfect app. Get it and forget it until you need it and you’ll see what I mean. ### 5/5 — App review *2023-08-04, version 1.93* As a subscriber to various publications and visit knife & tool websites, I find myself referencing “ Knife Steel” app frequently. It is thorough, in a handy format, and gives the information I want in a useful way. I thank you for such an informative website on steel and it’s uses. ### 5/5 — Knife steel *2023-07-25, version 1.93* Very helpful info! There are so many steels that companies try to pass off as “great knife steel!” But the real story of alloys can be quite different when you can go to a reference for the real story. ### 5/5 — A GREAT took! *2023-02-02, version 1.93* This app provides an added dimension to collecting and owning knives. Thanks! ### 5/5 — Literally better than google *2022-12-13, version 1.93* If you have ever wondered about knife steel, for instance when buying a knife, this app will give you a quick and easy to understand answer. ### 5/5 — Very Handy Reference *2022-11-05, version 1.93* I use this app whenever confronted with a new steel. It's a very good reference to separate the steel wheat from the chaff. Thanks for all the hard work making it !! ### 5/5 — Great app *2022-10-29, version 1.93* I think I’ve had this app for about a year now, super useful if you want to know what’s in your pocket or looking at a knife online. Honestly can’t think of much to improve, well done to the creator on this one! ### 5/5 — Awesome resource *2022-10-28, version 1.93* I don’t think I’ve ever looked up a steel and not had information about it. A great resource for steel nerds. ### 5/5 — Great App *2022-10-27, version 1.93* One of the most comprehensive and easy to use apps that I have ever used. Well done!!! ### 5/5 — This is my Go To *2022-10-18, version 1.93* When I find myself unsure or simply guessing, this is my Go To Application. It is loaded with information and references and cross references. Check it out. ### 5/5 — Best App For knife Steel Info *2022-10-13, version 1.93* This is by far the best app hands down for when I have to look up a blade steel and do some comparison. It has not let me down, and is spot on with all the info it gives. It is also recommended by many fellow knife enthusiasts and YouTubers. If you need one app that can keep you informed, get this one and it will not let you down. ### 5/5 — EXCELLENT APP *2022-04-04, version 1.93* Excellent for quick reference to check quality of a knife or axe or whatever is made of steel. GREAT JOB ON THIS AND THANK YOU. ## Most critical reviews (10 lowest-rated) ### 1/5 — Impossible to navigate *2025-02-02, version 1.93* App navigation and design make no sense. Make it look like an iPhone app, read the HIG. ### 1/5 — Useless App *2017-09-10, version 1.80* This app does almost nothing. It tells you the basic composition of knife steel. But it is full of spelling mistakes which leads one to question the accuracy of all the technical information. No information about heat treating or tempering. All in all, a waste of disk space. ### 2/5 — Great data, very poor search engine *2017-03-31, version 1.80* This would be a really great app if only there were a decent search engine. The search really just goes to that alphabetical spot in the list. For instance if you search for M2 steel you get no results yet the database has M2, and there is a link to it from CPM M4 steel. Too bad, the information is really excellent and took a lot of work to compile. ### 2/5 — Great selection but... *2013-05-02, version 1.4* The app completely crashes when you try to select an element in the steel composition chart ### 2/5 — Needs Work *2013-04-02, version 1.4* The idea of this app is very useful, but it is poorly designed and very buggy. If some of these issues were resolved it would find far greater acceptance as the resource the maker purposed it as. ### 3/5 — Pretty good, but… *2023-06-27, version 1.93* The list of steals is fairly comprehensive and covers most of what knife makers would want to know in relation to the composition. However, I would’ve given it five stars if it actually included heat treat information as well. ### 3/5 — Simple but… *2017-10-16, version 1.80* Simple UI and excellent search facility with a pretty comprehensive database but good grief it needs proofreading! Also contains some subjective opinions and not just straight facts. ### 4/5 — Knife steel nut *2024-12-04, version 1.93* I’m just a steel junkie! Every time I get the urge to buy a new knife I come here to remind me what steel I need ### 4/5 — Fast and Good INFO on steel classification! *2019-12-09, version 1.92* Has good info on steel but lack general info that can help regular people without knowledge in steel for knives. For this reason I had rate it with four stars. Perhaps, this will help to get more info on the app or from other sources. ### 4/5 — Solid reference for evaluating and choosing steels *2019-05-15, version 1.92* This is really the only game in town. A well written, easy to navigate app with useful and appropriate commentary. Pulls the so many many hundreds of current and recent steels into some order, so you can begin to understand what makes a good steel (why is lowly ol’ 420HC the chemical basis of many 21st century super steels? How about 1095 and D2, why are they still around? Read on). Not perfect, and necessarily incomplete. We wish Zvi would issue a true 2.0, we’d gladly pay for that! ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent Resource *2026-07-29, version 1.93* I find myself checking this app almost daily. As a knife nerd, this is a very useful and easily accessible resource. ### 5/5 — Great app *2026-02-26, version 1.93* Been using this app for years now. It's a great reference for identifying and classifying different steels (not just for knives) from across the globe. ### 5/5 — Is the app still being updated? *2026-02-04, version 1.93* App is awesome but some relatively newer steels have not been added and the entries don’t seem to have been updated at all in like 4 years. ### 5/5 — Very Helpful App *2025-12-10, version 1.93* This app is very good for somebody who wants to be able to look up a kind of steel without having to go and search for. The only thing that had had was a way to compare different deals side-by-side. Considering it’s free there’s gotta be some give. ### 5/5 — Excellent tool *2025-11-30, version 1.93* If you’re a steel nerd, like to see the components of a given steel, this is for you. ### 5/5 — A must for a blade aficionado! *2025-06-22, version 1.93* I use this to learn and also judge my next purchases by. If you like blades of any kind. This is a must have app. I have collected knives for almost 50 years. I will open the app during a layover or waiting on a customer for a meeting. I learn something every time I open it up. ### 5/5 — Knife Enthusiast. *2025-06-18, version 1.93* Great resource for knife makers, dealers, or anyone who appreciates knives. ### 5/5 — Extremely helpful *2025-04-19, version 1.93* This app is awesome. I don’t even make knives or swords (yet) so it’s not only for those guys, i’m interested in the many steels available to us today for knife and especially sword making! This app has it all, the chemical makeup that a lot of us enthusiasts like to nerd out on, in search for the “perfect” steel(even though it doesn’t exist because it’s relative to your use and application of the steel so what’s “perfect” for one application wouldn’t be for another). Hence the need for such an app! To decipher what steels are best for what type of blades etc. Just get it! You will enjoy it if you have EVER looked up a steel’s composition, or if not, you can start now with this app! Here’s to your knowledge. ### 5/5 — Great Research tool *2025-02-10, version 1.93* Handy and educational ### 5/5 — Howell A *2025-02-04, version 1.93* Outstanding resource for KNIFE nerds everywhere! Highly recommend for anyone who enjoys knife, collecting or KNIFE making. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
