These are not knives

[Teofilo]

Do you know what these are for?

[I'm Still Bison]

Are those solid or hollow shafts?

[Roadie]

I'd say they are for tapping trees

[Teofilo]

hollow shafts

[I'm Still Bison]

 I'm with Roadie,they look like they're meant for tapping into trees

[Teofilo]

I do not know how they are called but here back home we use this tool to pick into sacks of rice to determine its quality , if you know what these are called, can you share it with me please?

Is it copper? Oh,and I think it is for tapping into trees also. But, if it is copper than it would probably kill the tree. I know that if you put a copper screw into a tree, it kills it..
