This was something that has been there for quite a while.
If you try to open a can and you hold the item to open the can (can opener, knife, hatchet, etc) in your hands and press RT the character will perform and finish the animation but sometimes it stays closed in the inventory. On the 2nd try it will mostly work.
If you hold the can in the hand and combine it with the tool in your inventory then it will work on the first try.
Easy to reproduce.
