I've seen them before and think they should be useful, but in my experience this product doesn't work. I sanded a bike frame with it. the "blades" are relatively short and stiff. You have to apply a good amount of pressure. Otherwise, only the outside edges will touch the canvas. Even with pressure, contact with your work surface is relatively limited and you're only effectively using 10-20% of the sanding surface. Due to the additional pressure, the material wears out quickly. The "blades" tend to wear down the edges and become too smooth to be effective. Maybe I'm doing it wrong, but I believe the individual "blades" need to be a bit more flexible and maybe a bit longer to work. .
