The product is exactly as advertised and is a high quality straight edge with a precision ruler. It makes an excellent dual-purpose straight edge and ruler. I find, however, that I mostly want to use it as a straight edge and have lots of other rulers to use for measurement. The thin design of this straight edge makes it fairly easy to knock-over so I find myself being very careful with it to avoid damaging the straight edge, my workpiece, or my equipment when I accidentally (and quite easily) knock it over. If you're really looking for a straight edge and don't want to have to baby-it then look for a different product. If you want (and really need) the dual functionality then this a quality ruler/straight-edge combo.

They are not Starret or hand scraped Bridgeport, but they are pretty darn decent for the price. A company that sells these for luthrie use charges 80% more for a less accurate product.  I know if you put the words, gun smithing, luthrie, jewelry, etc in front of a simple product the price goes up 50%-500%. These are kinda thin, but they are supposedly parallel so the non knife edge is also straight. They work quite well for me. .001" will make a guitar not play at all on one string at that fret. So far these are working fine for set ups on instruments and tools alike.Rockler ships fast, and safe.
