Fasciq IASTM Tools are made of a high quality surgical stainless steel, and are used by professional therapists for loosening fascial structures. They mobilise the fascial soft tissue. Stainless steel is the most suitable material for IASTM Tools because it resonates. Information provided by the tissue about agitated structures can be felt by the therapist through the tool. The therapist scans the condition of the tissue by stroking the skin with the tool. In that way, he or she can feel where blockages are present that need to be treated.
