The Tech heads are the same during the period when the razor was made. Try the fat handle. These handles are still somewhat short, but average length for that period. A modern stainless steel handle will feel a bit too heavy and unbalanced, but fun as a change of pace.I apologize if this isn’t the best place to ask but I have a post-war travel tech. Is the head the same as a normal ball end handled one? I’m not interested in using the tiny handle so if it’s the same head then I’ll just see if I can find the longer handle. Or is it better to buy a complete one? Probably dumb questions but I was hoping someone else has run into this situation before. Thanks!
