I was flattered when I received a PM from Dr. Brown today with a link to a review he did on a pen I sent him. It is of the Kaigelu 316 and it is ground to a stub. I must admit that maybe I ground it for writing at a slightly lower angle than he is used to based on his comments. It was basically a stab in the dark and not something I consulted him on beforehand. I just used comments he made in his videos and trying to see how he holds a pen in his videos. I still have lots to learn. It is nice to get a second opinion though. Up until now, there is only one other person that has tried one of my grinds and he said he liked it.
