Walnut sorting kit, Poltava region.

A nut cracking kit is a set of tools designed for cracking the shell after a nutcracker.

When processing walnuts both at home and at enterprises, part of the nut remains uncracked and requires manual cracking or re-splitting with a nutcracker.

The nut splitting kit greatly simplifies and speeds up the process of splitting the shell, prevents injuries and scratches, and does not damage the core.
