Thanks everybody for the info. It seems like the answers are don't worry about the tip, it won't break and if it does I get a new one; SR101 is great, although not quite as tough as SR77 but holds a better edge; it is a great all-around knife so get one!

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.
