Very sharp, easy to use with no rubbing on my hands.  I use these for cutting paper and sometimes fabric for collages.  It makes it very easy to get close accurate cuts when you need to make curves and tiny little shapes.  I highly recommend these.  I should admit, however, that I have not been using these for very long so I can't comment on how long they hold up.  I am expecting them to last  a long time because others who have them in my artist community have been very happy with them for a long time.
