If you're going to use this thing, do check the carbide (sometimes
ceramic) cleaning blade.  You want the edge to be sharp and smooth; if
it's nicked or chipped, it will end up doing more harm than good.

I suspect that a carbide insert for machine tools might be cobbled up as
a replacement, if required.
