The 2017 Guide Rod Assembly includes L-brackets, 8" Guide Rods, and Ball-Joints. These Ball-Joints have broached, threaded studs which fit a 1/8" Allen Wrench. Use an Allen Wrench to thread the Ball-Joints closer to or farther from the sharpener's Vise to make micro-angle adjustments. Then use the Knurled Jam-Nut to lock the angle in place.This system is much smoother and easier to operate than the pre-2017 Hinge/Collar/Guide Rod System.
