Review on Excel Blades 55700 Sanding Stick by Steve Quinn

Works as expected. Surprisingly well designed. An indispensable tool for every model builder. This is much better than sharpening rods or files for fine work. If you gently rotate a strip of sandpaper each time it clogs, you can get a surprising amount of life out of it, especially if you're using one of those big rubber erasers (usually used on belt sanders). The only problem is that it's very hard to tell what grit is - you have to use a color coded key which can rub off after using the strip for a while. So if you want to cycle through multiple grains, get yourself a couple of these sticks so you don't have to keep switching grains on the same stick, and then you're spot on.
