The following glossary is expected to grow as I use technical words in my articles. It is not by any means complete at the moment.
Technique aiming to split a log with a knife. The cutting edge of the knife is placed on the top of the log and the back of the knife is pounded with a heavy stick. This will force the knife to penetrate the log, thus splitting it.
A hobby consisting of being able to live in the wild with ease and some elegance. Thanks to a lot of knowledge and know-how, bushcraft allows life in nature by using it but without harming it. The main subjects of bushcraft are: fire lighting using ancient techniques, shelter building, hunting / fishing and gathering, tool crafting (usually by wood working). Bushcraft is not survival, even though they share some commonalities.
A ferrocerium rod is composed of a metallic alloy very similar to a lighter’s flint. It is also frequently referred to as a "firesteel". When vigorously scraped, it produces very hot (around 3000°C) but very short-lived sparks. With a little training, a ferrocerium rod is as efficient to light a fire as more conventional ways (matches and lighters). It has the advantages of having no mechanical parts, being quite sturdy and indifferent to water. However, it is not a panacea, it is rather a good practice to consider it as another efficient way of lighting a fire to be added to the other more common ways.
Hook shaped knife which allows to carve recesses in wood. This allows to make spoons, bowls etc. There is a large variety of hook knives.
A finnish word which designates a wooden drinking cup. In a very cold environment, like in Lapland, a wooden cup does not transmit heat, unlike a metal container, while keeping the heat of the beverage. Bushcrafters like to carve their own kuksa with simple tools (hatchet, Scandinavian knife and hook knife).
