Open Knife

I have a Victorinox Swiss army knife that is hard to open the blades and things.?

Does anyone have any ideas how to free it up, so that all the blades open freely?

they are all tight ,try cleaning it real good ,sometimes lint from your pocket will get between the blades and bind them up,try some synthetic oil and work the blades,i have carried a tinker deluxe since 1985 and the blades are still stiff,they need to be if you use it like a tool as it is designed
