It is definitely about having something special and taking pride in that item. It is touted as THE most important tool. I grew up with the mysticism of swords like Excalibur and Robin of Sherwoods Albion. A symbol, something to remind you of what you want or need to do or become and having a constant companion you can rely on throughout the years, but at the same time, something that you need to look after for it to work. Sure, I can use a Mora, but they are impersonal and if it breaks, I can get another the same. They lack that extra spark of pleasure and familiarity in use, and if lost, it doesn't hurt. Custom knives are all about personality, pleasure and memories that grew over the years. You do get attached to inanimate objects. Well I do anyway.
