Because of the high level of detail that can be done by a master engraver, faking engraved designs is almost impossible, and modern banknotes are almost always engraved, as are plates for printing money, checks, bonds and other papers that should not be faked. Engraving is so fine that a normal printer can not make the detail of hand engraved images properly. In the U.S. Bureau of Engraving and Printing, more than one engraver will work on the same printing plate, making it nearly impossible for any person to duplicate all the engraving on almost any banknote or document.
Many classic postage stamps were engraved, although the practice is now mostly confined to particular countries, or used when a more "elegant" design is desired and a limited amount of different colours is acceptable.
Engraving machines such as the K500 or K6 by "Hell Gravure Systems" use a diamond "pen" to cut cells. Each cell creates one printing dot later in the process. A K6 can have up to 18 engraving heads each cutting 8,000 cells per second to an accuracy of 0.1 µm and below. They are of course fully computer controlled and the whole process of cylinder making is fully automatic.
The engraving process with diamonds is state of the art since the 1960s.
Now, laser engraving machines are being made and even today the mechanical cutting has proven its strength in economical terms and quality. More than 4,000 engravers make about 8 million printing cylinders worldwide per year.
The earliest allusion to engraving in the Bible may be the reference to Judah’s seal ring. (Genesis 38:18), followed by (Exodus 39.30). Engraving was commonly done with pointed tools of iron or even with diamond points. (Jeremiah 17:1).
Each of the two onyx stones on the shoulder pieces of the high priest’s ephod was engraved with the names of six different tribes of Israel, and each of the 12 precious stones that adorned his breastpiece was engraved with the name of one of the tribes. The holy sign of dedication, the shining gold plate on the high priest’s turban, was engraved with the words: “Holiness belongs to Jehovah.” Bezalel, along with Oholiab, was qualified to do this specialized engraving work as well as to train others.—Ex 35:30-35; 28:9-12; 39:6-14, 30.

Skateboard
A skateboard is a board (called a "deck") with four wheels put on under it. It is used to go skateboarding. The first skateboards were a piece of wood with rollerskater attached to it. This became popular and by 1960, skateboards were made in production. As more skateboards were made, more people liked the new sport. However, it was dangerous and people started to fall off. As a result, skate parks started to close down. With less places to skate, skateboarders had no where to go. A small group of skateboarders carried on skateboarding in the street and around cities. After 20 years, the sport began to grow into what we know now. Skateboarding is a popular sport with many younger riders. Young people sometimes skateboard on the street. There are many different types of skateboards like stunt skateboards, penny skateboards, Longboards, short boards and more.
The normal parts that make a complete skateboard are the deck, trucks, wheels, bearings, hardware, and griptape.
But digging in further, there are so many differences. There are soft skateboard wheels which are better for going fast and rolling over small debris and rocks, and hard wheels that are usually used by the pros and most skaters at the skatepark.
There are many different types of trucks, hardware, and bearings that have different ABEC ratings.
Most decks are made with six to nine-plywood layers. Other materials used in making decks fiberglass, bamboo, resin, Kevlar, carbon fiber, aluminum, and plastic. All these make the board more light. Some decks made from maple plywood are dyed to make many different colored plywood. Modern decks are different in size. Most are 7 to 10.5 inches wide. Wider decks can be used for greater stability when transition or ramp skating. Skateboard decks are normally between 28 and 33 inches long. The bottom of the deck can be printed with a design by the maker or it can be blank. And there are so many different skateboard deck brands to choose from.
The longboard, a common different kind of skateboard, has a longer deck. This is mostly ridden down hills or by the beach. The longboard was made by two surfers; Ben Whatson and Jonny Drapper. One of the first deck companies was called "Drapped" taken from Jonny's second name. "Old school" boards (those made in the 1970s–80s) are mostly wider and often have only one kicktail. Different kinds of the 1970s often have little or no concavity, whereas 1980s models have deeper concavities and steeper kicktails.
The Skateboard deck concave is noted mainly in three types: low, medium, and high. While the low concave is having small curvature and makes the safe ride, but you can’t put more stress on the edges deck. Medium concave will easily found in the present market due to the high demand for a beginner. High concave is raised more at the edge, making it perfect for performing Flip tricks and Ollie. Medium concave is readily available in the market because it suits beginners, which keeps it always in demand.
Grip tape, when put on to the top of a skateboard, gives a skater's feet grip on the deck. It is most often black. However, it can come in many different colors like clear. Clear allows the top of the deck to be decorated. It has an adhesive back and a sandpaper like top.
Interstate 95
Interstate 95 (usually called I-95 or 95) is a major Interstate highway that runs north to south in the eastern part of the United States. It is about long. Its southern end is at U.S. Route 1 in Miami, Florida and its northern end is at the Canadian border in Maine. It connects many major cities in the eastern half of the United States.
Portions of the highway have or used to have tolls. Many parts of I-95 were made up of various toll roads that had already been constructed or planned, particularly in the northeast. Many of these routes still exist today, but some have removed their tolls.
Many notable bridges and tunnels along I-95 were also tolled. The Fuller Warren Bridge, spanning the St. Johns River in Jacksonville, Florida, was tolled until the 1980s and was replaced in 2002. The Fort McHenry Tunnel is underneath the harbor of Baltimore, Maryland and was opened in 1985. The George Washington Bridge, opened in 1931, carries I-95, US 1, US 9, and US 46 (latter is officially considered to end at the NY state line) across the Hudson River between New Jersey and Upper Manhattan.
A study that could lead to the imposition of tolls on I-95 in North Carolina is under way as of March 2010.
Federal legislation has identified I-95 through Connecticut as High Priority Corridor 65. A long-term multibillion-dollar program to upgrade the entire length of I-95 through Connecticut has been underway since the mid-1990s and is expected to continue through at least 2020. Several miles of I-95 through Bridgeport were recently widened and brought up to Interstate standards. Work has shifted to reconstructing and widening of I-95 through New Haven, which includes replacing the Pearl Harbor Memorial Bridge. Environmental studies for reconstructing and widening of I-95 from New Haven to the Rhode Island state line are also progressing.
