Does anyone know what size the screws are on a Rat 1? The handle screws are wider than 2-56, but smaller than 4-40 and I'm not sure what size the pivot screws are either. Any help is appreciated.
 
I don't have a Rat to measure, but Rats are made in Taiwan, so they could be (are likely to be) metric screws. A 2-56 screw is .086" diameter, a 4-40 is .112", and a 2.5mm is .098", putting it between 2-56 and 4-40. I'd look at M2.5x.45 as a strong possibility. Knifekits.com carries 2.5x45 in .110", .178" and .230" lengths.

edit: No idea on the pivot screw, though it's likely to be something between 3 and 4mm.
