I am in Centurion and would love to give them the edge they deserve.Think the logical answer is just that the TI's are harder steels and take more patience to get right. I had no such trouble with any of my other razors, just the TI's, and that includes all three of them. Looks like they just need more attention. Hope they will reward me in the end!
Like I said, I do like them, just wish they could shave as well as some of my other cheaper razors!
