I had some plywood sheet cut to size in B&Q a couple of years ago and
the cut edges were quite splintery and ragged - a not very sharp blade,
I think and the operator almost said as much. It didn't matter a toss
in my application.

However, now I need some 12mm ply sheets cut where the quality of the
cut edge does matter. What should I reasonably expect? Do these places
usually make good quality cuts?

Cheers
