Since one of the first jobs I ever had and did for a few years is what they used to call an Oiler on heavy equipment, I knew right away what it was for.
It also reminded me of a couple of tools I have had for well over forty years now that I would imagine are as rare as Hen’s teeth, as they were really hard to come by even back then.
Let’s see how many of you will know what these are for.


Even better, a show of hands from everyone who has ever even seen these tools before personally?
I will tell you from experience that these things are the original Knuckle Busters.
