I've only made a few knives, but I don't doubt that the fact that I fix bicycles for a living helps me or has helped me with this stuff. Fixing bikes requires a surprising amount of improvisation, and I've found that making a knife from scratch requires a fair amount of creativity, problem solving and planning. That I own my own businesses I think has helped my self confidence which in turn allows me to approach knife making with some self assurance. My mountain biking, which I don't do professionally, has taught me that hesitation=death, so there's a little get-up-and-go, or even 'get back up' that I bring to my knife making endeavours. Also, the humility of being thrown violently to the ground and once again admitting that I'm fallible, (literally

). In my school days, I studied Art- its history- and methods and tools for making it. I own a small trail building company, in addition to building trails for my own enjoyment/sanity, and that really helps with the using of knives, (especially BIG ones, which are generally my favourite to use

). With all that I do, I get to carry knives whenever I like, there's no one to question that or give me a hard time. My little knife store business has been a great introduction to a large assortment of different knives, and the exposure to them has taught me a lot.
This is a big question, lots of answers keep coming to mind, but I gotta get back to work.
