It could be for personal use or decoration. Sometimes we choose our own but sometimes it's chosen for us. Little or big, different shapes and sizes, carried in pockets or worn on belts... Most importantly it has to be widely useful, razor sharp and comfortable to grab. The greatest gratification of our knife is not something that's out there by the dozen but custom made for our taste. A well crafted knife is a real pleasure to use or even just to held. Sure enough it needs to be pampered and taken care of however that will feel like a pleasure rather than an obligation. We clean it, sharpen it, treat it with oil.
I love knifes and I'm driven to make pieces that would capture people's heart.
