The fireplace tongs separated and are no longer usable. Looks like there is a bolt that broke between the two pieces. Is this reparable and if so, by whom? If not, are they replaceable or do I have to buy the whole set again. Sure hope not! Please advise.

If these are heavy duty iron forge tongs and have sentimental value, bring it to a blacksmith or a welder for a heavy duty rivet install; if it is too costly and less expensive to just replace the tongs with new ones- that would be your best choice.

However, if you are a do-it-yourself project type person, you can go to the big orange or big blue box stores (or even your local hardware store); bring the tongs with you, and explain that you want to repair them- a slightly loose stainless bolt (slightly smaller in diameter than the hole) and a nut will work.

Better yet, even an auto parts store that sells 400 mill grade stainless steel bolts for exhaust systems will work too.
