which engraving came first....in what order? what's the best years to buy? is it better to have an older one with the easy open modifications, or a later one that just works to start with? do any of them seem to hold up better than others?
how much abuse can they take? i am about to buy a used one and i am wondering all these things.
would it be expensive to have TC do the easy open thing with it?
