Another huge reason it's worth it...
The other knifemakers. By and large, in my life I've never met a group of people who are more willing to share their knowledge, take time to talk to you and encourage you to follow your dream.
Most knifemakers whether they be stock removal or forgers are artist types, independent thinkers, innovators, non-judgmental. I'm developing friendships with several makers that I believe will last a lifetime.
It was the drive to make a knife that got me started, it was the other makers here and those I met in person thT helped me make it a reality!
