I only have very limited experience with it playing it in a store, and I end up walking away with a K4 which I think is a nice blade-eccentric multitool.
Being a Vic and Traditional knives fan, I have no issue at all with all the unlocking blades or tools. T4 is decent if you really want a one hand opening and locking blade, but I find it quite annoying to 'fan out' all the tools each time, just to access one particular tool in a chassis. The chassis is also unnecessarily bulky and heavy. Contrary, Victorinox tools are more refined, easy to access with nail nick and more concise in build.
