Stealth Tri-Knife – Double Razor Edge Utility Tool

This compact triangle-style utility knife packs serious cutting power into a small, lightweight design. It uses two standard box-cutter razor blades, arranged in a dual-edge triangular layout to create a precise, sharp, ultra-compact cutter perfect for opening packages, trimming filament, cutting supports, scoring materials, and general workshop use.

The blade sandwich system locks everything together securely using four M3 x 10mm countersunk screws paired with M3 nuts. Assembly takes less than a minute, and when the blades dull, you can swap them out instantly.

The included ergonomic handle gives you excellent leverage and control, making the TriEdge a surprisingly capable everyday tool for makers and hobbyists
