The interesting thing is that my dad never sold his business, and when he shut it down, he kept all of his inventory. For the past 30 years or so, the bowhunters in the family have had a lot of feathers, shafts, inserts, broadheads, tabs, armguards, gloves, etc., to use when hunting.
Dad passed away a few years ago, and since then I have become more involved in trad archery. I have toyed with the idea of starting a small archery business, and have a significant amount of inventory that I could start off with, right away. But I've decided against it, considering the costs, economies of scale, tight competition, the time it would take to run it, and the relatively small market that so many other 'archery entrepreneurs' are already tapped into.
I say that if you know how, and are able to make it work, go for it! But I think it would be tough... too tough for me, at least.
