Hi everyone, I'm totally new to collecting knives (started this month, previously just owned a super cheap Gerber) and am debating purchasing a fixed blade bushcraft knife for backpacking/camping as well as just joy of ownership. I'm more than a little unclear about the difference between the terms "custom", "semi-custom", and "factory". I had assumed that custom meant handmade one-offs? And if so, I don't get how you can have a middle ground that is semi-custom. Thanks in advance for any replies, still trying to get the lay of the land here.
