About two months ago I was given a Razorscribe as a gift from a friend who is also a finish guy. He told me this was going to change the way I scribed. I was skeptical. I first used the Razorscibe on a refrigerator side panel, stain grade, that had been manufactured with a 3/8″ scribe strip on the back edge. The wall was out 3/16″ with a slight belly near the bottom. I set my panel plumb with the back of panel touching the wall at the furthest place out of plumb determining that I needed to remove 5/16″ of material to flush out at the face of cabinet. Using the 5/16″ setting I ran the Razorscribe down the wall with the blade tilted up at a slight angle using slight pressure. It leaves a very discernible line. I then cut my scribe line with a jigsaw as close as I could leaving maybe a 1/32″ off the mark. I finished with a grinder with a 80 grit disc. When I put the panel to the wall it married up beautifully to the sheet rock. One mark one time and done! This thing works. I have since used it to scribe baseboard and toe kicks. Seriously. This thing works.
