What exactly is a sod, anyway. It sounds like a drunk, but I really have no idea. I like it though, and from what I can tell, you fit the bill bragging about your technique, Dr.
RT--If I had to go with a "can't miss" linen strop, it would be Dovo, V-weave. If you don't see a one point hht improvement with that one, something is wrong. I hear Tony Miller has great linen but I have not received mine yet. The only one I cannot heartily recommend is the Kanayama and that is my own fault. It feels so different from my others that I haven't given it a fair trial yet. I have been concentrating on other more interesting tests. I really believe that just about anything can make a good, maybe not great, first strop. Ask Gerritt or Chris. They have numerous examples. I use a tool belt belt half the time because that is what is in the kitchen by the tap where I hone a lot, and even it will give very noticeable hht improvement.
Hope it helps, Denny
