I purchased some round blanks laser cut from sheet. The edges were incredibly hard and a file would barely touch them. So beware, you may get a shock when you try tidying up the cut. . In my limited experience, you don't get this problem with water jet cutting.

Jason B seems to be happy with his laser cutting, so hardness of the cut seems to vary.

Hello ,I had some laser cut connecting rods .Very accurate, saved me hours of work with the hacksaw .The only trouble I had was the out line was so hard couldn’t touch them with a file ! So out with the blowtorch heat up to cherry red and left them to slowly cool . That did the trick allowing me to clean them up with a file ! and emery cloth .Hope this helps someone struggling to clean up laser cut parts.

The hard edge on laser cut is very thin, went over mine with a flap wheel and it was then file-able. A diamond file would probably work as well.
