Homebrew PCBs

After cutting a few boards to size on the band saw, I now realize how 
abrasive they are and how quickly then can dull a band saw blade (made 
for wood cutting).  I have used the table saw (with a carbide tipped 
blade), but again, suspect this may cause premature dulling.

I have heard about shears and even paper cutters, but am not sure if I 
am thinking of the same shears and papers cutters being disscused.
