Re: Dura Edge Blades

From:Connie McManus <>

Primarily, I use Surgipath teflon coated blades and have no problem with
them at all.  However, I also use Leica blades from time to time and I have
noticed this last shipment of blades has not been very good.  Some blades
fresh from the dispenser  cut just like something I would discard!  I
prefer the Surgipath blades over the Leicas because they last longer and
cut much nicer sections, but these Leicas are worse than usual.  Is Leica
and Dura Edge made in the same plant, maybe???
