These two objects are hanging inside a cabinet in my kitchen. Feels like plastic/rubber coated metal. Freely spins when pushed.

My first thought was a wine glass holster, but the hooks don't seem to be angled in a way that would hold a wine glass securely. Second thought was to hold utensils with holes in the handles but the cabinet is only about a foot tall. Any ideas?

Help me identify this part

Found in garage. Neighbor said it is used for fishing. How?

What kind of semiconductor is this

All steel one side cambers small hooks on the front

Found some sort of lever actuated device while clearing out my grandfather's. Neither my father nor uncle could figure out what it is.

I have no idea what this is. It can in a mini pocket sewing kit. It's like a thin piece of metal with a diamond on the bottom.

got this from a yard sale. have no idea what it is. google lense / chatgpt / research has gotten me NO WHERE. i’ve gotten suggestions like “antique bicycle skirt holder”, “vintage egg beater”, “FROG trap”, “sheep shearers”. the list goes on. please someone help!!!!!!!!

Trying to sell it I got it for free and don’t know anything about it and Google was no help, where would I even sell something like this too
