The advantage for me is the stability with little or no backlash when advancing the sample or making a cut, a serious problem with my larger and more expensive hand microtome. This one is very simple and well made. I did lap the top for smoothness - sharpening stones or a couple of grades of wet/dry sandpaper will

Mine was silver, so I liked that better than the picture. The well is about an eighth inch deep and almost half an inch in diameter. Very smooth screw. Also it came on the first day of the 6 day shipping window.

The top is not quite flat and also has burrs that would dull the razor blade. It needs to be flattened, smoothed, and deburred (using a sharpening stone or sandpaper on a flat base) before use. Once this is done, it is usable and inexpensive device.

Works great. Used it with a carrot, and used it with wax. I am able to make thin slices. The wax method allows for the best and thinnest slice.

This is a good theoretical microtome. As it's the only one available for noncommercial use, there could be a better designed one.
