Anybody on AR have any experience with the Italian Viper knives? I would like to know of people's opinions on quality and workmanship. Here is one example:

Since no one has answered your post, I'll just throw out a few thoughts.
I have no experience with their knives. If I were looking to buy that knife, I'd try to find out more about the N690 Co stainless steel they use for their blades, it's chemistry and heat treatment, how hard it is after draw. That hardness after draw (as you get the blade) is important in that it is an indication of how long the blade will stay sharp, and how easily it can be resharpened.
Anybody that uses titanium liners is interested in providing a top quality knife, so that's an indication that the knife is top drawer.
I like the design too; good looking folder.
