Common buckthorn is native to Europe and parts of northern Africa and  western Asia. Introduced into North America in the 19th century as an ornamental shrub, it has since spread so extensively as to become naturalized. Considered an invasive species, attempts at its eradication yield raw material for vibrant woodturnings. 

304 Grade stainless steel is comprised of at least 50% iron with no more than 0.08% carbon. With that much iron content it would seem the material would be subject to corrosion. Yet, it is the elements represented by the second set of numbers, 18/8, that chemically protect the iron. The 18/8 designation refers to how much chromium and nickel respectively are present in the stainless steel.  In example, 18/8 stainless steel has 18% chromium and 8% nickel. The chromium acts to bind oxygen to the object's surface thereby protecting the iron from the process of oxidation. This protection is enhanced by the presence of nickel. The greater the nickel content, the greater the corrosion resistance.
