Kitchen gadgets! Growing up, we called the one in front a "church key", probably because they were indispensable at church suppers. One end is for punching holes in the top of tin cans. The other is for popping off bottle caps.
In back is a more modern take. One end is for prying up pull tabs. The other is for unscrewing plastic bottle tops and on the other side for untwisting twist-off bottle caps.
Both get used a lot.
@sbourne in my recollection, they were called "Church keys" ironically back in the day because they were used to open beer bottles.
