Cutting Blades

Cutting Blades
please tell me what wood cutting blades fit the Dewalt DW321 jigwaw, bayonet or otherwise?

I have bought this jigwaw on E Bay and it came with no blades, i have now purchased some blades but still cant get them to fit, i am starting to think that the blade changing system does not work

Did you buy blades made for that make and model saw? If you go to Home Depot, Lowe’s or Menard’s, they will have blades to fit that saw unless it is like a zillion years old. Even then, they will most likely have them.
