I feel like, with this and every revenue generating venture I've been involved with, by the time you are ready to start selling at a level where you are generating a stream from outside your friends and family, you will know the answer to that. If it is a question you can't answer yourself, maybe you aren't ready to push that hard.
I only say this because 1. Your first question here was about selling and price. No introduction to speak of and no biba fides. 2. By that time you should have been exposed to the broader marketplace, see other works, annd probably know where you stack up with QC. 3. What I ask for my knives is going to be different than anyone else on the planet. Some take in to account materials more. Some take labor more. Some take infrastructure more. And some take demand more into account. The reason why is we are almost all affluent in one dept but flat broke in the others.
Introduce yourself, show some work, tout the resume a bit and make friends.
Welcome! And yes, read the rules. Wouldn't wanna get poo'd on the first post.
