I began with an EJ89 as many other new guys do then I bought an old type to try something drastically different but havnt quite mastered it yet. I also bought a nice looking tech which I believe is from the 40s. mr. razor lists it as a slim handle tech and looks like a skinny version of the fat handle. I shaved with it today and it was a superb shave! I thought it might be poor as I hear people saying they're too mild but I found it did the job just fine! my question is.... do each of the different styles of the tech shave differently? or is it a case of 'if you've tried one, you've tried 'em all' just with different handles? thanks guys
