transpixel The blade is in place! It is made of a flat steel strap used by carpenters for connecting beams together. There is a steel tip welded at the end to act as a thin point (while a rail could be filed down to the right shape, the aluminum would not be very robust). The pivot is made of a half inch diameter steel rod welded to the bottom of the plate and resting into an oversize tie. transpixel
