Diamond grit files, available in 220 or 320 grit, should be cheap in small sizes 
(under $5. for a small one, like 15mm x 75mm), and cut glass very quickly.  Use 
with lots of water to prolong grit life (the diamond takes years to wear out but 
will get knocked off the file with hard dry use).
Get them at lapidary stores, gun shows, or some hardware stores.
