The picture above is a cut out or releif that was nothced into a concrete floor. This was done to allow us to install a hand scribed hardwood material. The hardwood of choice was a tight vertical grain doug fir solid 5/4 by 4" wide. As you can see the cement does not cut perfectly with out some small chiping.

You can almost say that it looks like it grew there, the fit was perfect for this application. This was not a single sided scribe, but was actually a double side scibe. These were over 18' long a had to be as perfect as humanly possable.
