2.75" by Parisian. On the underside, stone is in nice condition but the metal collet has heavy oxidation with tiny pitting although fully complete. Whatever aged the collet also produced a little tan staining on the front but mostly mixed in with the dark blue rim so that it is hardly apparent with exception of three or four tiny faint dots on the white lettering. Rest of the celluloid has some general surface wear but overall the piece still displays Extremely Fine. See other knife and sharpening items #601-606.
