This song is totally about the civil rights movement! it SO shows! (I'm REALLY sorry if this sounds racist, but the Blackbird is an African American experiencing the civil rights movement) Here are a few lines: Blackbird singing in the dead of night: during slavery, the slaves had to do things under cover.
USAR Concrete and Metal Cutting Diamond Blade. The USAR concrete and metal cutting diamond blade is the diamond blade that rescue teams have been waiting for. It cuts through steel, concrete, and cast iron with incredible speed.
A sword's strength comes from the flexibility of the metal such that it can absorb the force of impact. A rigid and brittle material like diamond would make for a terrible sword. A diamond edge, however, similar to the hard-tempered working edge of a Katana, is a possibility, but it would not be one solid piece.eah I knew diamond tipped saws were a thing, but would a diamond tipped sword, in the same fashion as a saw, be any better than a regular metal sword? Doesn't a saw essentially just repeatedly chip away at what it's cutting, not really what you want from a sword.
