Hello everyone,
I'm a big research guy, I love hunting for data and comparing it to learn more about a subject. This has lead me to try to put together a comprehensive steel comparison chart. I have almost completed a Mechanical Engineering degree and I am a hobbyist knifemaker so this (and a lot of curiosity) are my only credentials for the numbers I've arrived at so far. The list has three main columns which detail the main attributes of knife steels on a scale from 1-10. There is also a "total" which just adds the values from that row, and three columns which add two of the three attributes so that you can find steels based on certain tasks.
For example if I want to see the best meat processing steel I might sort the list by the highest combo of edge retention and corrosion resistance.
There are three major problems with this list:
First, it is an amalgam of dozens of charts and graphs from manufacturers and knife users and anecdotal evidence. this means that the data is very fast and loose and comparing between companies and people always leads to differences in perception and representation.
Second, the values are on a scale from 1-10, when I first started the list this wasn't a big problem because there were only a few, relatively similar steels. Once it expanded though I ran into problems where steels that were only one point away from each other were actually 200%+ different in actual test numbers. for example the early list had AUS-8 as relatively highly corrosion resistant, then I added H-1 and it made the two look like they were similar in that aspect..they are not..So it is important to look at it as a relative comparison, not an absolute one; meaning that a move from 5 to 6 is not an 11% improvement, it just means that steel with a score of 6 is some amount better than a steel with a 5.
Third, the chart does not include HRC values, grind angles, or thickness behind the edge measurements because this information is almost never provided. So the numbers are a sort of average between multiple sources of comparison.
Finally, I am posting this for the sake of learning and improvement. If you have an issue with some number, than please provide a counter suggestion and evidence for why. Ideally I would like opinions from people who have the steels they are talking about. one final note, I do not think there is room for "favorite steels" in this discussion, there are so many reasons to love even lower performing steels so please only discuss steels in the mindset of data.
Final, final note. I would also like to start including price and availability data as a point of comparison so if you have information on this feel free to chime in. **this is category that I will be adding over the next few weeks using know constants like 1095 as baseline for price scores.**
