I also saw on youtube one of the TT knives and the bigger choil on the newer ones looks good for choking up for some detailed work. Now my only decision is whether to get one with the milled guard or not.
The square choil was a drawback with the TT Reg although you could still choke up for fine work.
As for milled guard or not I'll be the first to say Definately get
One of each! You cant go wrong at that price.
