(a) It may not be possible to create clean angled cleaves in specialty fibers with large "air-fill" fractions due to the structural properties of the fiber.

(b) These cleavers are calibrated using standard weights that are hung off of a pulley, so the tension settings are programmed into the tablet controller in grams. This maximum tension corresponds to 6.5 kg.
