I would try using something

I would try using something like a staple in between the stock and point rail it has ben my solution in cases and heard of by another few people.

Yes there is

I assume the "blade" you are referring to is the "point rail".  If there is no power to the point rail up to the pivot point but you have power after the pivot point, then I would suspect a dirty pivot area.  Try to clean it with an electronics cleaner and see if power comes back.  If there is NO power to the entire point rail, then there is a break somewhere underneath where the factory runs connections under the insulfrog.  In that case, soldering a very small wire from a good power source to the point rail should be easy enough to do.  This can be done with the turnout in place.  

If you look very closely

If you look very closely there is a small metal tab on the bottom of the point rail that makes contact with the bottom of the outer rail.
That is what carries current to the rails in the frog area. VERY carefully ease it up a little at a time until you are sure it makes contact with the bottom of the rail. move it up a little and check it before you go any farther. It shouldn't take more than a few thousands to make contact. If you have any dental picks, they make a good tool to use.

If you go too far it will hit the side of the rail and block movement of the points. If that happens, bend it back down a little and start over. Just be gentle and go slow.

Good Luck
