An open flame will work, if you're careful.  Perhaps better.
IIRC, TAP plastics (who does custom fabrication) has three grades
of "edge finish."  there is the straight "routed" edge (as it comes
off the CNC router, I guess), a "flame polished" edge, and a full
mechanical polish...

taking apart a laptop lcd backlight can be very educational.  There's
a lot of interesting mechano-optical components in there that combine
to get an even backlight out of an edge-illuminated thing.  Not that
applicable to the small display you're using, but interesting.
