Manufactured by the American Safety Razor Company between the 1920's to 1940's, the GEM Micromatic is a all metal twist-to-open single edge (SE) razor. The model I have - thanks to a generous PIF from a fellow shaver - is a Micromatic Clog Pruf that was introduced ca. 1934.
The Micromatic takes standard GEM single edge blades, and like all TTO's changing blades is a breeze - just drop them in and close the hatch
It is perhaps the best performer of my small selection of SE-razor, but like the GEM 1912 and the Ever-Ready 1914 extra care has to be taken with the angle of the
razor. As with the other SE-razors I got the best results when the top of the head was flat or almost flat against my skin.
Can I recommend a Micromatic? Oh yes - I think it'll makes for a very nice introduction to the world of single edge shaving, as long as you remember to watch the angle.
