The mini tactical Nano Blade and Nano Ink are tiny but powerful tools that can be used to open boxes, letters (Nano Blade), and as a travel pen (Nano Ink).
I ordered the pen and blade set, received 2 blades and was promised to be sent the pen when in stock, the blade is convenient, it beats having to open my bag and rummage through my bag to find my folding knife to open boxes or slice a little something. Still waiting for the pen
