Exacto knife straight cutter V2

This handy tool holds an Exacto knife, making it easy to achieve perfectly straight cuts with minimal effort. It’s especially effective on foam boards, giving you clean, precise results every time.

Version 2 features a built-in spring mechanism that automatically retracts the knife when you’re not applying pressure, enhancing safety and convenience. Installing the spring is optional, allowing you to customize the tool to your preference.

Assembling the tool requires 2 M3x10 bolts, 2 M3 nuts and one M4x40 bolt. The optional spring mechanic additionally requires the spring from a ballpoint pen and a short strand of filament to secure the spring mechanism.
