The initial three instruments
Monolithic tape core
Carved from a continuous 1.4-kilogram block of 6061 aluminum. The weighted center spins on ceramic ball bearings with an integrated tool-steel serrated shear blade.
840g cylinder weight
Turned on a four-axis lathe from raw naval brass. The base features micro-machined radial grooves that secure architectural drawings without adhesive or surface clamp distortion.
Milled pen trench
A geometric graphite-black tray hollowed to an exact parabolic profile. Sized to seat two drafting instruments cleanly with acoustic dampening cork recessed beneath the base.
