Useful painting tools?

These painting tools look useful, I'd like to try them:

Lisa Schmitz, the owner of Whispers From the Moon, shows us how to use Catalyst Blades and Wedges with heavy body acrylic paints and mediums. As an artist and clinical therapist, Lisa draws upon a variety of body-centered modalities, indigenous ceremony and creative expression. Lisa loves using heavy body paints and mediums to cover large areas of canvas, then working back in with color & texture detail. Located in the Historic Oak Park Art District, Whispers From the Moon is a haven for creative expression and personal awareness.
