These things are used in forests where it rains, and when used they end up in the wet insides of a deer or in the damp wet ground in the forest. They are made from stainless steel, so they arent single-use, and doesn’t rust up and get dull before being used.

In addition people often use VLANs for security segregation. For example you might buy a bunch of cheap Chinese security cameras, but want to ensure that they can’t send anything back to the manufacturer. Then you can make a VLAN with no Internet access for the cameras.
