Standard pen clips fail when bent past their elastic limit into the plastic deformation region, causing permanent deformation. Inspired by carabiner designs, the solution uses a bent-wire spring mechanism that can freely rotate away from the pen body, limiting stress on the material and preventing permanent deformation. ## Full article daily.dev links to this article rather than hosting it.
