Blowpipe (tool) The term blowpipe refers to one of several tools used to direct streams of gases into any of several working media. If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot. Jewelers and glassblowers engaged in lampwork have used the blowpipe since ancient times, with the blast being powered by the user's lungs. For small work, mouth-blown blowpipes may be used with candle"
"punches, a bullet punch, Havana punch, and multi-punch. The bullet punch is a bullet shaped device that fits on a keychain. The punch can be twisted to expose a circular blade, used to cut a hole in the cigar cap. This cut is preferred by some, as it exposes less of the filler and binder and reduces the chance of tobacco ending up in the mouth. Critics of this cut maintain that the smaller hole does not allow as much smoke to come out and the hole is often clogged with a saliva and tobacco buildup. One problem associated with"

"device called a sliding sleeve, or sliding side door, which is a hydraulically operated device, built into the production tubing. During normal operation, it would remain closed sealing off the tubing and the annulus, but for events such as this, it would be opened to allow the free flow of fluids between the two regions. These components have fallen out of favour as they were prone to leaking. Instead, it is now more common to punch a hole in the tubing for circulation kills. Although this permanently damages the tubing, given that most planned well kills are for workovers, this"
"Knockout punch A knockout punch, also known as a chassis punch, panel punch, Greenlee punch, or a Q-max, is a hand tool used to punch a hole through sheet metal. It is a very simple tool that consists of a punch, die, and screw. There are three different drive systems: manual, ratchet, and hydraulic. First a pilot hole is drilled slightly larger than the screw of the knockout punch. Then the die is placed on the screw and the screw is inserted into the pilot hole. The screw is then threaded into the punch and the screw tightened until the"

"Blowing horn The blowing horn or winding horn is a sound device that is usually made of or shaped like an animal horn, arranged to blow from a hole in the pointed end of it. This rudimentary device had a variety of functions in many cultures, in most cases reducing its scope to exhibiting, celebratory or group identification purposes (signal instrument). On the other hand, it has kept its function and profile in many cattle raising, agricultural and hunter-gatherer societies. The oldest ones were wood and animal horns (usually ovids and bovids). The earliest findings in Europe are Bronze Age"
"Powder horn A powder horn was a container for gunpowder, and was generally created from cow, ox or buffalo horn. The term may also be used for any personal container for gunpowder, regardless of material or shape, for which powder flask is the strictly correct term. Typically there was a stopper at both ends, in later examples spring-loaded to close automatically for safety. The wide mouth was used for refilling, while the powder was dispensed from the narrow point. In some cases the point was closed and the mouth used for both, with a powder measure, a type of scoop"
