Review on Inch Hand Sanding Mouse Block by Pop Henneghan

There are 2 different styles of these hand sanding blocks - one that quickly tapers to almost a point, and a slightly more rounded version with no point. Think of the shape of a triangle and a semicircle. The first one I bought a while ago was half round and I liked the ergonomics better for my hands. They're a little less comfortable for me in the triangle shape, but they both work the same way and hold 5" sandpaper (velcro style, not included). I keep 4 of these with different grit sandpaper mainly to chip off the edges or get to the edge where my random orbital sander can gouge the surface.
