Manufacturer's Description: "The Swiss Army Knife of IASTM tools
that comes with instructions and demonstration videos for only $129. Why buy 4-5-6 tools when one will
do the job? Stop switching tools in the middle of treatment just because you
need to use a different shape edge. All you really need is a simple straight
edge, a convex and concave surface. You also get 2, different size, small convex curves for
treating small areas or performing cross friction to individual ligaments. Each
side of this tool has a treating edge. One side is slightly rounded (sharp) and
the other is more rounded. Use the more rounded edge for patients who do not
like the standard edge or for low pain threshold patients and first time IASTM
patients."
