Depending how close you need to get to walls, doorways, or other obstuctions you can use a router, circular saw (use a plywood blade), or a grinder held on edge. The grinder will get you closest to the wall.

Don't force it, get a bigger hammer

Use a circular saw, with this jig:

Make a jig out of two pieces of ply one factory edge 5" and the second 10". Use the factory edge and nail/screw that on top of the 2nd piece, run the saw down the ply with the table against the factory edge.

This jig will be good enough to make cabinets on site with, it is a saw guide jig we use it quite often when the job isn't large enough to warrant bringing the table saw.
