Precision Woodworking Jig for Limited Tools

The user needs to trim a miscut wedge accurately but lacks a band saw and is looking for suggestions with limited tools. This highlights a need for specialized accessories or jigs that enable precise cuts using common workshop tools (like a router or circular saw) for intricate or remedial tasks without requiring large, expensive machinery. A product could be a universal precision trimming jig designed for use with handheld routers or circular saws, allowing DIYers and hobbyists to achieve professional results with their existing equipment.
