CRL Professional Glass Chipping Tool - Heavy Duty Glass Breaker for Emergency Escape, Auto & Home Safety - Perfect for Car Windows, Home Windows & Emergency Situations

This is a Mirart TP33 with a CRL label stuck over the Mirart label.That being said the tool is adjustable and the included instructions are useful in creating artistic scalloped edges in glass and mirrors. I've found (not to my surprise) that some grinding is needed to soften any sharp edges that are created. I've just started using it for a few trial projects - so expect to learn more as I go along. I gave it 3 stars - based on my perceptions of cost versus utility - even though the build quality is very good.
