I've been following This Old Tony (TOT), AvE, and similar channels for some time. Not that I'm a practicing machinist, but some aspects of those arts relate to my job and I find the content of those channels more entertaining than anything Hollywood has put out in a looong time...
Anyway, didn't know TOT was also a hobbyist knifemaker, but here is his version of a knife sharpener.
