The EDGE is THE ORIGINAL 300 grade stainless steel tool for assisted soft tissue manipulation from Buffalo, NY. I have always been interested in other big name approaches but did not want to pay the prices. I am an orthopaedic manual therapist who teaches in both APTA and AAOMPT accredited fellowship programs. I developed my own tool with different edges for different areas of the body. It is lightweight, has a comfortable grip, and even certified practitioners of the "other" techniques have used it and found it more comfortable and easier to use. It's several tools in one! The EDGE is used by professionals all over the world! Some organizations that use the EDGE: NFL, NBA, MLB, NHL, division 1 schools, smaller colleges, high school ATCs and of in the capable hands of PTs, DCs, MTs, and ATCs.
