Davinci Tool Firm
on October 17, 2011
I had high hopes for this, but was a little disappointed. I like the wide, square-ish, sturdy shape of the base, which is easy to under control and doesn't damage furniture upholstery too much.
The size and firmness is fine and very handy. But, I find the edges/corners of the tool to be far too sharp. I would have preferred more rounded edges. This can be very painful on the skin if not used while wearing a shirt or clothing.
The only side that is really worth much is the one with rounded posts. The wedge posts and the scalloped concave edge are just too sharp when attempting to dig into deep knots, and can damage the skin if you're not careful.
The rounded posts are Okay for superficial and wide-spread knots in the rhomboids and *posterior* supraspinatus, infraspinatus, and teres major & minor, but for deeper knots in the rhomboids, levator scapula, deep erectors, and anterior scapula muscles there is just not enough focus--not for me, at least.
I found myself going back to an old 5-post, 5-inch-tall wooden knobble sort of thing with 5/8" wooden balls on the ends of the dowels in order to properly get into the deep knots and cords. This wooden thing also does me better for latissimus insertions into the humerus, while the Davinci tool just couldn't target that area well enough.
I do have to say that the rounded side performs better than a standard medical occipivot device for getting to the occipital area and the superficial levator and erectors immediately to either side of the spinus processes.
Good to start with on superficial tissue, but I'm still looking for something to replace the wooden-posted thing so that I don't stretch deep pits into my leather couch while I watch television.
