I am using the Silberschnitt
I have been using the Silberschnitt for about 9 months now and am fairly pleased with it. The wheels cut a clean score and the glass breaks out well. The suction has held firmly and the scale is easy to read and the cutter adjusts easily and securely. However, mine has the slightest wabble in it and I have to be sure to get that slack traveled before I put the pressure on for the cut. It does not seem to have caused any real problems with the cuts so far but it is disconcerting. Also, I have not cut any really difficult glass yet – just straight opaque and transparent stuff. Hope this helps.
