What can tell you about this?
Theres one tool I carry in my own picking kit as its an incredibly versatile addition. Imagine a quick stick with a long handle, then you are into what the probe is based on. But its more than that, you can use it to feel locks, counting pins or feeling which ones might be high security, you can actually rake with it as well. Its a truly versatile tool.
Theres one more use for a spiked tool with a handle in an emergency situation, so it pays to always have one handy.
