Every one of these, with full specifications, is inside the app. More are added with each update.
A printed hook chart was fine until the shop ran out of your size.
A fly tying hook chart lists hooks by manufacturer and model alongside their specifications — size range, wire strength, shank length, gape and eye type — so tyers can pick the right hook for a pattern. Traditional charts are static PDFs covering a single brand; the Woolly Bug Hook Finder is a searchable database covering 700+ hooks from 16 manufacturers.
A hook comparison chart (or cross-reference chart) maps equivalent hooks across manufacturers — for example, which Ahrex or Fulling Mill hook matches a given Tiemco model. Hook Finder does this instantly by comparing real specifications rather than relying on out-of-date printed tables.
Search for the hook you know in the Woolly Bug app — by brand and model — and Hook Finder shows comparable hooks from other manufacturers matched on shank length, wire strength, gape and eye type.
Yes. Both Tiemco and Ahrex are in the database, along with 14 other manufacturers, so you can cross-reference models between any of them.

No. Hook Finder lives in the Woolly Bug app, where you can search all 706 hooks, filter by specification and see equivalents across brands. Reference pages for individual models are published on woollybug.com/hooks/ for looking something up, but comparing and finding equivalents is done in the app.
