Abstract: A reefing line pressure reducer and a reefing line cutter assembly are deibed. The pressure reducer is an element which can be incorporated into a reefing line cutter assembly to reduce pressure at the tie-off knot of a reefing line by enlarging and rounding the surface area circumscribed by the knot. The subsequent reduction of pressure at the tie-off knot reduces the likelihood of reefing line failure and consequently, poor system performance or canopy failure. The reefing line cutter assembly consists of a pyrotechnically actuated reefing line cutter, a cutter bracket, and a reefing line pressure reducer.
