Short answer: At the beginning, Greg Medford would run his Magnacut at 59 HRC out of caution. He said "I was sort of sneaking up on its performance." At least since this video below in 2022, he's been running his Magnacut at 63 HRC.
If the forum blocks the site, look for "Blade Talk LIVE with Scab & Joes Feat, Greg MEDFORD. of Medford Knives." It's dated August 8, 2022. At around minute 23, Greg explains his experience with Magnacut and current heating practices. Here's a transcript I put together for my future reference and hopefully to save others the pain of finding no answers online.
Greg Medford: "Magnacut came along and it’s got some really interesting properties to it. It does something unexpected and very counter-intuitive and as I experimented with it I wasn’t comfortable with it so I kind of came up slow. I was sneaking up on its performance so what happened when we initially launched Magnacut, we backed off on the hardness a little bit because it just spooked me. I was like, ‘I don’t know, man—I’d rather have it a tiny bit softer than as hard as they’re saying because typically as hard as they’re saying these tips chip and the edges break and it causes me lots of problems.’ So I went with something I know. I got it to a hardness I like. Now, there’s a lot more data and there’s been a lot more people using it and now, you know, our Magnacut’s 63 on the Rockwell Scale instead of 59 like I did it oringally. It’s now 63….As it turns out, Magnacut is the only metal here on planet earth I’ve ever heard of that is tougher at 63 Rockwell than it is at 60. It’s bananas. Super cool. I just didn’t feel comfortable right away going to warp speed; I wanted to kind of sneak up on it….I would rather have a knife go out and the guys are gonna freak out about this 2 percent below its metallurgical peak performance in an area that I’m familiar with than go out with me searching for peak performance on a brand new steel on the first model I put out and find out they break all the time. So, you learn with experience. I kind of sneak up on it and it’s ok."
I wanted to share this because I couldn't find information anywhere on the web and I believe this discussion board could use a good influx of new information since it's turned into a dunk session on outdated facts.
