First I made a mechanical computer keyboard, including num-pad and wrist support. Used two objects, one for the keyboard base and one for the keys. The keys were created by making an array of one key, first in the x-axis, then those in the y-axis. Then some deleting extraneous faces (keys) and resizing.
Next I created a sword and shield, also two objects. Shield mostly consisted of extrudes, and scaling the center to a point for the spike. Made the handles by splitting a torus object in half and snapping them to the face of the shield.
Sword used some extrudes, scaling, and some loop cutting for the grip.
