Best can opener I have ever owned.  I did not know that these existed and have been fighting with the "dirtiest inch in my kitchen" for years.  This cutter does not enter the can, but cuts a fine line at the top of the can.  The cut is smooth and there is no danger of cutting yourself on the raw edge. Unlike other can openers you do not have to remove the blade and fiddle with it to get it back on.  Will be telling all my friends about this one!
