I'm a newbie maker, (if you call someone who has been making a few knives a year for 15 years a newbie) who has recently started making a lot more knives and recently attended a one on one three day forging seminar. I'm getting better.
I also work for Timken (on the bearing side, not the steel side). If I want to purchase it, I have to go through Admiral also.
My whole point is to just say Thank You for purchasing our steels!! I have discussed the specs and properties of the 20CV with our metallurgists and engineers. They've told me that Timken 20CV outperforms S30V on Edge Retentioin and stainless properties, while being as tough as S30V.
If anyone needs heat treating specifications for either the BG42 or the 20CV, please just holler at me here or call me on my cell phone at (330) 284-3103.
