Metal parts look like aluminum. The handle is coated in a rubberized material that feels strong and durable and feels great in your hand. The clamps at both ends are spring loaded and remain open for loading. The build quality is excellent. The description says it uses 1/2 sheet of sandpaper because its width is 3 1/8 inches, not exactly 3 inches. The extra 1/8" width means you only get 2 strips from a standard 9" x 11" sheet of sandpaper and the third strip is only 2 3/4" wide. If they made it exactly 3 inches wide that would be perfect. I could deduct 1/2 star for that, but this item is so well made I'm rounding up to 5 full stars.
