The M-85 Ratchet features metal and 5 protrusions at a 8.5 millimeter height, identical to the 5- series of Ratchets. Its name M-85 refers to the added metal ring that is riveted to the underside of the Ratchet. At the time of writing, this metal ring makes M-85 the heaviest Ratchet, at an average weight of 10.6 grams. M-85 uses a simple attachment mechanism, also seen with the 4-55 and 3-85 Ratchets.
