Herb grinder

An herb grinder (or simply, a grinder) is a cylindrical device with two halves (top and bottom) that separate and have sharp teeth or pegs aligned in such a way that when both halves are turned, material inside is shredded. Though the manufacturers claim they are intended for use with herbs and spices for cooking, they are often used to shred cannabis, and are often unsuitable for actual use with spices (which instead are prepared using a burr grinder), resulting in a product that can be more easily hand-rolled into a "joint" that burns more evenly. Herb grinders are typically made of either metal or plastic and come in a variety of colors and polished metals. Some grinders have two or three compartments instead of just one, with fine screens separating the bottom compartments from the ones above, thus allowing the marijuana trichomes, also called kief, to be collected separately. The widespread adoption of cannabis as a recreational drug in recent times has caused herb grinders to become synonymous with weed grinders. There are many types of herb grinders out there, from electric to hand cranked, in various styles. Advertisements describing them as "spice grinders" have sometimes confused buyers who were unaware about the actual intended use. It can be made of different materials, such as aluminum alloy herb grinder, zinc alloy herb grinder, plastic herb grinder and wood herb grinder.

A smoking pipe, often called simply a pipe, is a device specifically made to smoke tobacco. It comprises a chamber (the bowl) for the tobacco from which a thin hollow stem (shank) emerges, ending in a mouthpiece. Pipes can range from very simple machine-made briar models to highly prized hand-made artisanal implements made by renowned pipemakers, which are often very expensive collector's items. Pipe smoking is the oldest known traditional form of tobacco smoking. Some cultures of the indigenous peoples of the Americas smoke tobacco in ceremonial pipes, and have done so since long before the arrival of Europeans. For instance the Lakota people use a ceremonial pipe called čhaŋnúŋpa. Other cultures of the indigenous peoples of the Americas smoke tobacco socially. The tobacco plant is native to South America but spread into North America long before Europeans arrived. Tobacco was introduced to Europe from the Americas in the 16th century and spread around the world rapidly. As tobacco was not introduced to the Old World until the 16th century, the older pipes outside of the Americas were usually used to smoke various other substances, including hashish, a rare and expensive substance outside areas of the Middle East, Central Asia and India, where it was then produced. A pipe's fundamental function is to provide a relatively safe, manipulable volume in which to incompletely combust a smokable substance. Typically this is accomplished by connecting a refractory 'bowl' to some sort of 'stem' which extends and may also cool the smoke mixture drawn through the combusting organic mass.

The bowls of tobacco pipes are commonly made of briar wood, meerschaum, corncob, pear-wood, rose-wood or clay. Less common materials include other dense-grained woods such as cherry, olive, maple, mesquite, oak, and bog-wood. Minerals such as catlinite and soapstone have also been used. Pipe bowls are sometimes decorated by carving, and moulded clay pipes often had simple decoration in the mould. Unusual pipe materials include gourds (as in the famous calabash pipe) and pyrolytic graphite. Metal and glass, seldom used for tobacco pipes, are common for pipes intended for other substances, such as cannabis. Common pipes include metal smoking pipe and silicon smoking pipe.
