One workshop. One loop. Always getting sharper.
The Forge is everything an archnerd actually needs under one roof: build the arrow, tune the bow, log the practice, print the tape, score the broadhead, see your wind drift modeled per vane choice with the air pocket visualized on the diagram. One workflow.
And at the end of the day, none of them made you better.
Built on Kaizen — constant small improvements compounding.
The tools, individually.
Each surface stands on its own. Save a bow, run a scenario, share a URL. Sign-in unlocks cross-device sync.
Wind-Drift Visualizer→
Compare two builds in 3D under your wind, altitude, range. Forge Score updates live. Measure your tune from a bareshaft offset or group photo.
Build Review→
Full read-out on your active arrow: warnings, balance, FOC, spine ladder, stability, trajectory, weight breakdown. Share the URL.
Spine What-If→
The only spine calculator that models extended-length inserts (Firenock CTI, Iron Will Snyder Core, Evolution glue-in, Easton DG). Built on Stu Miller’s dynamic-spine math.
My Bows→
Save your bow specs once. Auto-loads into every other tool. Primary bow flag for the one you reach for first.
My Arrows→
Build profiles per shaft + components. Active arrow flag drives the visualizer, the review, the spine ladder.
Methods & math→
The full methodology behind the Forge Score, the trajectory model, the spine math, the Ashby penetration coefficients. Read it, argue with it.
