There's lots of ways you can get in the industry! But I don't think there's any that you can just jump head first into and find immediate success unless you're already majorly connected to the industry (family, colleagues, etc) or very lucky. Everything here seems to take time, patience, and a long time of building yourself and business before things run smoothly. Things like Kickstarter are giving people who have a solid background in Marketing and Design fast and HUGE growth opportunities but depending on how you'd like to appear to the rest of the community you may need to weigh your options. If you have people in your area looking for a service that you think you can provide that's usually the best way to go. For instance I'm from a VERY small forested mountain county and a lot of people here barely know how to turn on the ol' Google Machine so things like retail, sharpening services, and custom work go a long way. These things can supplement you while you work towards the bigger aspect of things like online business and dealing with the big dogs in the knife world.
I'll try to compile a list of things I think you could do in this world, some will need either a reputation or following, most will need a decent investment:
Knifemaking
Sheath making
Abrasives supplier
Materials supplier
Marketing
Design (logos, knives, website schemes)
CAD drawings
Entry level job at knife company
Retail sales
Knife flipping (might get some hate lol)
Brick and mortar shop
Sharpening services
Knife mods
Reviews
Waterjet or CNC services
Building grinders or tools
Invent a new process or tool for the industry
Anodizing services
The best way, imo, is to just wholeheartedly follow along with the industry. Follow as many makers as you can, watch as many videos, attend as many shows, classes, or tours as possible and just keep waiting and thinking. Something will come, something will eventually click, and you'll know what to do based off your skillset. Hope this helped a bit!
