Hunting knives vary greatly by appearance, which is determined by their different functions. At the dawn of the history of firearms, hunting knives were full-fledged cold weapons and were crucial because sometimes it took too long to reload guns. The blade size of early hunting knives was much bigger than the blade size of modern hunting knives. Bowie knives were used in America, big daggers in Russia, and special hunting dirks in Europe. Today, a knife is more of a hunting accessory so its cutting characteristics and dimensions differ from the standards of the previous century. A modern hunting knife is not a weapon, but a universal tool used to skin game and to dress a carcass.
Hunting knives differ by types of design - from up-to-date extra-portable models to large, middle ages style knives with massive guards and wide blades. Generally, hunting knives are divided into two large groups: folding or all-in-one-piece knives. One of the most popular knife types is a bowie knife; its blade can be 20-33 cm (8" to 13") long. Various stilettos and daggers are also very popular and are designed for finishing off wounded animals or self-defense. Leading cold weapon manufacturers tend to produce high-carbon steel knives, which are very compact and handy.
All-purpose lock knives are gaining more and more in popularity. These knives are equipped with additional tools such as a fine saw, a dressing blade, a skinning hook or a screwdriver and they are available in various combination of tools. It is debatable if it is more efficient to buy an all-purpose knife, or if it is more practical to carry a toolkit because a screwdriver, a file, and an awl are more usable as separate tools.
