The Parallel A3506 is a limited edition folding knife that blends cutting-edge engineering with artistic laser engraving. Designed by Vosteed in collaboration with Blade HQ, this model features a titanium handle with a multi-color topo pattern and a premium 2.90-inch S35VN reverse tanto blade—making it both an everyday performer and a collector’s piece.

Limited to only 300 numbered pieces, this exclusive release includes a cosmos splash titanium knife bead created in partnership with Reylight. The Topo-Satin version is precision-engraved using advanced laser techniques, where modulation of the laser’s frequency and speed creates vibrant, interference-based color patterns on the titanium’s surface. This fusion of science and craftsmanship adds visual depth and individuality to each knife.

Weighing just 2.36 oz and measuring only 0.28" thick, the Parallel is impressively slim—thinner than a pack of gum—making it one of the most pocket-friendly titanium folders available. Ideal for office carry, the reverse tanto blade shape excels at practical tasks like opening packages and slicing paper, while S35VN steel ensures exceptional edge retention and easy maintenance.

The ambidextrous crossbar lock and dual thumb studs provide smooth, secure operation for left- and right-handed users alike. With a reversible stainless steel pocket clip, aluminum backspacer and thumb studs, and minimalist styling, the Parallel is designed for comfort, control, and understated elegance.
