no it is in fact a first class lever because a see-saw is first class and this is basically a see saw except instead of a handle on each side there is 2 on one side so therefore its a first class but people think it is a second class because of scissors but this a scissors have a difference and that difference it that when using scissors when you move one handle, it moves on the other side of the fulcrum but with a can opener the handles make the actual metal that opens the can move not just the same thing but on the other side
Load is in the center, as in a wheel barrow or a bottle opener. Having an acronym might help remember which class is which. For example: 3-2-1 - ELF! means that for a class 3, the effort is in the middle; class 2, load in the middle; and class 1, fulcrum in the middle.
