Worked perfectly. I had dropped my mouthpiece and dented the end. This tool rounded it out nicely.

This tool is not stainless steel. The reason I say this is the tool came with rust on it consistent with the properties other than stainless. If it were 410 stainless ( a ferritic stainless ) it would have had rust "freckles" as opposed to wide spread rust in two places. The working surfaces were free of rust and performed as expected. I don't know how this tool was stored nor why they would ship it in the condition it was. This is the first negative review which I have written on an Amazon product, and I hope it is the last one that I have to write; their products are shipped in good shape. I will not return the item because it is usable - it's a cosmetic thing.
