How Do I Find A Buyer For Burning Bars?

I have about 125 exothermic cutting bars that I want to sell. A detailed description is at divegearhere[dot]com/en/welding-and-burning-c-4/oxylance-10-burning-bar-p-46

How do I go about finding a buyer for these bars? They are an item that the average person is not going to need. I was thinking someone on this forum might have some insight on locating potential buyers. Any replies with advice or ideas would be appreciated.

Thank you
