Looking to scribe some acoustic wall panels and PIR boards to get as flush a finish as possible to some not so straight walls over the coming weeks. What scribe tools would you recommend? I have the Tracer pencils (which I get on with), but their scribe tool seems *very* plasticky. The Trend EasyScribe seems to be reasonable, but would certainly be interested in people's real world experiences (and happy to pay a little more for something of decent quality!)
