I think fix blade knives will have a limited market place, that said I really do like the look of the product and will consider one, I have done a bit of spoon carving in the past and hope to get back to it this year. The review you have on bush raft is very good.
Kitchen knives may be more sellable and the Instagram set is probably a good place to market yourself, do you market these knives on Instagram? I couldn’t find you having a quick look earlier.
Good luck with the venture.
