Böker's reissue stays faithful to the original WWI-era German signal-corps tool, whose concave, notched edge was designed to strip insulation from field-telephone cable without nicking the wire inside. That same edge doubles as a fire-steel striker today. The switch to rust-resistant 440A steel is the one concession to a century of use since the trenches.
Böker's reissue stays faithful to the original WWII-era German Wehrmacht tool — issued to pioneers, signal units, and mechanized crews — whose concave, notched edge was designed to strip insulation from field-telephone cable without nicking the wire inside. Böker's own page pitches that same edge as a fire-steel striker today. The switch to rust-resistant 440A steel is the one concession to the decades of use since.

Corelle's Vitrelle glass is laminated in three thin layers rather than fired as a single thick slab, which is why the plates are so much lighter than they look. A 15-year owner on r/BuyItForLife reports the set surviving constant dishwasher cycles, several apartment moves, and the occasional drop onto tile with no chipping or crazing — the kind of longevity that's rare in dinnerware at any price.

description: "A gesture-based algebra app built on an open-source 'conditionally-sound' engine that makes invalid algebraic moves physically impossible to drag into place."
promotedTo: wyrm-math
---
Wyrm Math is a gesture-based algebra app for iOS and Android (with a browser demo) built on an open-source engine the author calls "conditionally sound" — instead of letting you make a move and then flagging the error, the interface simply won't let an invalid step land. You drag terms across the equation, and if a move would break the algebra, there's nowhere to drop it. The result is a workspace where the usual trial-and-error of solving equations gets replaced by a constrained set of moves that are always legal.
