Remanufacture or create a modern version of the discontinued Pocketwrench II tool.
This post clearly shows a strong, unfulfilled demand for a discontinued product. Commenters are vocal about their desire for a spare or to own one for the first time, with phrases like "desperately want a spare" and "I've always wanted one." This is a low-risk opportunity since the market demand is already evident. The product would be a re-creation or an improved version of the Pocketwrench II, possibly using modern materials like titanium or adding features such as reversing the wrench hole for a more natural feel. The target market is the EDC (Everyday Carry) community, tool enthusiasts, and anyone looking for a compact, versatile multi-tool. Revenue would come from direct sales, likely gaining quick traction within these online communities.
