Most everything from the current production will fit, but the newer saws and blades are a fraction of an inch too long (scissors are a no go as well). If you are comfortable grinding down the tips of the saw and blades, they will fit fine.
Now as far as is it worth $10? If you end up liking the tool, definitely. But, personally, id stay away from it. The only real advantage of the Paratool over the competition is that it is fairly comfortable in plier mode. But, the inside tools are just ok, and the pliers have a tendency to fold in use (or, are difficult to open, depending on the tightness of the plier pivots)
