Vet88, to provide further education on metallurgy let me first start by outlining this. Hardness is a great factor to consider, but it is not the only factor. There are other mechanical properties such as toughness for a quick example which are critical in the making of a good steel. Hence if I simply told you my steel has a Rockwell of 55 and then you asked "OEM-B" who said that their product called "LS4" had the same Rockwell, you might be compelled to think both companies blades will hold the same for edge retention and durability. Which is far from the truth. It would be like saying plexiglass and wood have the same hardness value and hence are the same material and will behave the same way. Which, is far from the truth; if you try to bend both, snap both, or bang both against each other, very different things will be found. A prime example is the breakage rates on LS4s which were snapping like candy sticks and had high volume warranty issues. Our steel holds its edge much longer not only due to our hardness, but also the other mechanical properties and our processing techniques. By using a high carbon stainless, and having a good ratio of Fe, C, Mn, Si, P, S, Cr, Mo, Ni...etc...etc. alloying elements we make a great steel. We used to publish extensively what we used and our processing techniques, but really now, not even 1% of people would comprehend or appreciate the subject matter, so it doesnt make sense to communicate it in depth and in fact it only harms us by allowing new entrants (who are all copy-cats anyways) a quicker advantage to follow our recipe. Sorry to not be of more help, but hope that gets your head into the brief underworld of metallurgy. Onto some facts now, I can say our warranty is 1 year (go beat that) and even with that time, Im very proud to say we've had an extremely low number of issues and most issues were more in our early days when we were still tweaking and refining our process. On the edge side, one fun example is an NHL EM we work extensively with ran a player for 3 games (+ the practices in between) on a single sharpening (yes he checked thoroughly after every session, he is a pro, but the steel didnt need a tune). And yes, we find many beer leaguers / all players are able to cut sharpening down in frequency, or in keeping the same frequency, the edges only need a slight tune-up, it might be a 3-pass sharpen, instead of a cross grind and 8 pass re-hollow for example. We formed our company to serve the strict needs and demand of the NHL and other high calibre pro leagues. We want to not only be effective for its players (speed, performance, health benefits), but to make the life of the EM's more efficient and hopefully save them valuable time too. Again, tried to shed the light I can, hope it helps. Cheers 🙂
