The grind of a blade refers to the shape of the cross-section of the blade. It is distinct from the type of blade (e.g., clip point or drop point knife, sabre or cutlass, axe or chisel, etc.), though different tools and blades may have lent their name to a particular grind.
Grinding involves removing significant portions of metal from the blade and is thus distinct from honing and polishing. It is notably done when first sharpening the blade or when a blade has been significantly damaged or abused (such as breaking a tip, chipping, or extensive corrosion) A well maintained blade will need less frequent grinding than one which is not treated well.
The terms edge angle and included angle can be important when talking about grinding. The edge angle is measured between the surface of an edge and a line running from the point of the cutting edge to the back edge. The included angle is the sum of the edge angles. All other things being equal, the smaller the included angle the sharper the blade and the easier it is to damage the edge.
Thomas Leo "Tom" Clancy, Jr. (born April 12, 1947) is an American author, best known for his technically detailed espionage, military science, and techno thriller storylines set during and in the aftermath of the Cold War, along with video games on which he did not work, but which bear his name for licensing and promotional purposes. His name is also a brand for similar movie scripts written by ghost writers and many series of non-fiction books on military subjects and merged biographies of key leaders. He is Vice Chairman of Community Activities and Public Affairs, as well as a part-owner, of the MLB Baltimore Orioles.
Clancy was born in Baltimore, Maryland. He attended Loyola Blakefield in Towson, Maryland, graduating with the class of 1965. He then attended Loyola College in Baltimore, graduating in 1969. Before making his literary debut, he spent some time running an independent insurance agency. This agency thrived for a few years before joining a group of investors.
Clancy and his first wife Wanda married in 1969, separated briefly in 1995, and permanently separated in December 1996. Clancy filed for divorce in November 1997, which became final in January 1999.
Asher Paul Roth (born August 11, 1985) is an American rapper from Morrisville, Pennsylvania. Roth is signed to Schoolboy Records, SRC, and Def Jam.
Asher Roth was born and raised in Morrisville, Pennsylvania, a small town about 20 miles northeast of Philadelphia. His mother, Elizabeth (née McConnell), is a yoga instructor, and his father, David Roth, is the executive director of a design firm. His mother has Scottish ancestry and his paternal grandfather was Jewish. Roth does not consider himself Jewish, although his name often leads people to believe he is. He attended Pennsbury High School. Growing up, Roth was exposed to little hip hop in his family, with his parents preferring "The Temptations, Earth, Wind & Fire ... Bruce Springsteen and Dire Straits." According to Roth:
The first CD I ever bought was Dave Matthews Band's Crash ...That is how suburban I am...I finally got into hip hop in '98 when I heard the Annie sample with Jay-Z....When I wrote my 'A Milli' freestyle, that was me listening to 10 years of hip hop and not relating to it at all. Like, Damn I don’t sell coke. Damn, I don’t have cars or 25-inch rims. I don't have guns. I finally got to a point where I had the confidence to do this thing myself, and I was making music for me. And it turns out, a lot of people feel the same way I do.
