I also did ceilings with 2x2' tiles which already had the drop edge and had
to do the single cut edge of tiles that had to be cut for the periphery of
the room. Following a tip in an old Fine Homebuilding magazine, I made a
couple of cutters from 2x2x3/4-inch block of scrap wood. Cut a 3/8x3/8-inch
rabbet on one edge of the block and attach a SHARP utility knife blade with
round head screws to the face of the block so that it's cutting tip
protrudes about 3/16-inch into the rabbet. To aid in holding the blade, I
had first routed a 1/32-inch deep dado into the face of the block at a
50-degree angle to the rabbet.
I found the 2x2' acoustic tiles to be crumbly and had to regularly
re-sharpen the blade to get a halfway clean cut. It was adequate since the
cut edge faces the nearby wall making it inconspicuous. I wouldn't suggest
trying to cut all four edges of a tile; it'll look like hell.
