Adjustable Orifice Cleaner Reamer

If your question is what is it, then it is a small pen shaped device with a single point that starts really small(pin tip size) and gets progressively thicker. It is used to clean the orifice of gas appliance pilot assemblies. Costs from 50-75 depending on where you get it. There are other variations of the same device which some are smaller and much cheaper and you can get whole kits for $100+ but includes every size for every orifice.
