А knife is a cold edged weapon with a short and more often a one-sided blade.
In the most common meaning of this word it is just a blade with an edged side. It came into existence in the earlier period of humanity, and it was used for different purposes.
If we speak about the knife as about a piece of decorative, applied and armoury arts, we often have to forget about its practical use, even though functional qualities of any collection knife have to be at the very least same as of a simple knife that we use every day. However the more important characteristics are an artistic design and high quality of the manufacturing. Such items will be a decoration for any armoury collection. They will symbolize honor, strength, success and prosperity.
