Spade
Yes, it does sound like it belongs in the shed, but the spade provides a very precise massage. Its flat & narrow shape is perfect for targeting areas like the pelvis and shoulder blades.
Able to get deeper within muscle tissue, the spade can be used to zone-in on those hard-to-reach areas. It’s largely impossible to achieve a precise effect with hands alone, and this attachment allows you to deliver targeted relief to those smaller spaces.
