Can the blade be sharpened once it gets dull?

No. Most can't (induction hardened teeth). Some can, especially on
the wide blades for big saws, but it's not cheap.

I don't know if the Timberwolf blades have induction hardened teeth, but
I sharpen mine with a Dremel and chainsaw stone and it seems to do very
nicely.
