The device is unique, because behind the simplicity of the implementation with available means, a very logical engineering thought actually shines through. It seems a simple construction, but actually thought out and executed in a brilliant way.
I have also lived in a village - during vacations and weekends. My grandparents also had livestock, including a pig that was slaughtered every Christmas. But I've never heard or seen anyone do anything like that with meat. Nor did anyone bring such products home. It's your invention, obviously. 😊 And it's brilliant, that's my honest opinion.

I watched a Serbian TV series and was amazed at how many words we have in common. Some Polish words too. But these few common words do not help me at all in understanding a language.
