What the heck is that thing?

This is the tool that you might not need that often but when you need it, you can't not have it. I like how it slides together to make sure it taps straight. Most taps for bottom brackets fit this style. Had this on the bench for a long time, not a tool you quickly wear out so its durable, lastable and... able to last. Just expensive.
