The only blades I buy and will use are the Accu-Edge disposable blades.  I
prefer the low profile but they also make a high profile.
These blades last a long time without making lines,(unless you have hard
tissue ) but then any knife will be the same.   I get much thinner sections
with this knife than I can with any other blade because they are sharper.
They are expensive but well worth it.  I order them from S.P. or Baxter or
Allegiance, which ever name they go by now.  All the same company.
