Stop in for a cup of coffee

If they are that stuck they could use some WD40. Try it on the pivots too. They may not need springs just seized up.

The pivots are loose and fine, but I could not help myself so I had to lubricate them a little with the famous American 1-2-3 oil. :D Oh I love that old stuff, we used to have it in Norway too, all the way back in the 70ties and 60ties. Anyway, it seems it is fine now since I bent the end of the arm a little. And I do like the new blades, they look awesome instead of a black blade.
