I am bound and determined that I will only get knives that I will use. Heck, I would even use a rare big $ custom if I actually found one that I really liked. With Busse or SR, I just can't see myself NOT using arguably one of the toughest, most versatile knives in the world. It would be like buying the Mona Lisa and then storing it away in a cool dark place. NO WAY!!!
And because I only have two hands and a limited amount of spare time in which to use my knives, I think very hard about what I want a particular knife to do. When that task is covered, I might get one more that will do the same task and can act as backup in the event that something happens to knife #1. Because I have a few knives that are great at a lot of things, there is some overlap with task specific knives I have. But all in all, I have been able to keep my knife purchasing down to a dull roar with this simple practice, at least so far

. In turn, I actually find myself being able to spend more time focusing on things like sharpening, outdoor survival, etc.
Like anything in life (cars, power, women, guns, money, and yes, knives), it can be easy to get carried away. You just have to get control!
