WillowSpine

WillowSpine is a small offline manual for anyone who owns a fishing rod and would like the thing to outlast them. It also happens to tell you where the rod came from in the first place.

Five benches on the workshop wall

1. Eras of the rod. Bamboo antiquity through Hiram Leonard's 1874 hexagonal split cane, post-war Shakespeare fibreglass, Fenwick's 1974 carbon HMG, and the Osaka-driven Tenkara revival of the 1990s.
2. Rod types. Split-cane fly, tenkara, modern carbon fly, spinning, bait-casting multiplier, village cane pole — one card each, with the maker, the water and the reel that goes with it.
3. Care & storage. Six routines by cadence: rinse after every trip, wax the ferrules every three or four, inspect guides monthly, loosen ferrules in the off-season, check the wraps twice a year, store the whole thing flat in its tube.
4. Memory match. Twelve cards, six pairs, one clock. Match each rod with its maker, era or matching reel. Your best time is saved between sessions.
5. About. Sources, offline notes, no-network promise.

How it fits your day

Between trips it is a maintenance checklist. Off-season it is a shelf reference. Waiting in a car park with the rod in the boot, it is a quick memory drill.

Design notes

Parchment, willow-green and brass palette; Times-serif type; a hand-drawn bamboo-rod cross-section for the launcher. Nothing here needs a network — everything ships in the APK.
