I am guessing that 90% of woodworkers either don’t clean their cutting tools enough or at all. If you cut anything with a glue base (esp. MDF) or with a lot of pitch, it can really start to build up and produce an inconsistent edge. Pine cuts like butter, but it leaves enough residue to make the next hard (or worse, high silicate) wood function like sandpaper.
