I think he got his own property or something, so he went dark for a while. He's been pumping out new content fairly regularly considering the work that goes into them. It really filled a hole in my life that I didn't know existed.
I love his channel so much. I actually just saw a video that detailed all the imitation channels that popped up after his success and they went through and detailed how they go about it and all the lazy stuff you could see they were doing that tipped you off that it was fake (other people doing work in the background and heavy machinery tracks). It's apparently an actual business that some people do to fake make stuff by hand. This guy though sounds pretty legit and down to earth, I didn't even realize he was Australian, I just never considered his nationality before.
This is one of the only channels on Youtube I set notifications for. I wanna see his collected iron get smelted into a new, larger, sleeker blade...but of course whatever he ends up doing with it, I know I'll enjoy the video.
