So you have a laser cutter...

[GJK]

well there are many different grades of laser cutting devices.  the ones used for the project here are probably of a lot higher quality then you might find at a mid/low level print shop where your counters are done.
but dont worry, no one is taking your 'device' away from you.

Good 'cuz I love snipping counters!!!

One of the newsletters from Avalanche Press mentions the ash and scorching as a problem that was solved by (IIRC) switching to different print contractors so I'd say that laser cutters are fine when used by trained personnel.
