The Original Jacknobber II , uniquely designed for the 21st century, is the first in the Pressure Positive line of deep-muscle massage tools. The knobs at each of the four legs of the Jacknobber II can be used in many ways to apply deep pressure to muscular trigger points and tension. The smaller knobs provide more intense pressure while the larger knobs provide a gentler pressure. Use one knob at a time to press deeply into imbedded trigger points; use two knobs at a time on either side of the spine. Arguably this is the most satisfying hand held massage tool available.
