Destined to become a classic! The Master Spoke Wrench is an investment cast workhorse poured from the best steel, precisely machined, heat treated for hardness, then polished and plated. The result is a smooth, solid steel spoke wrench designed and built to fit perfectly in your hand and provide years of every day service. The SW-20 is a four sided wrench to grab the four corners of the square nipples.
