Some one else and me here thought a 1924 would do the trick (strong spring), but the side clips on that one prevent from loading half a de blade. The 1914 (also good spring) does not have such big side clips, so that one does work. So it is the 1914 that works for me. Loading half a de blade is about as easy as loading an SE blade
Can you show a picture of what you mean? I experimented a bit with half a no name DE blade and both my 1914s. The side clips got in the way, and the blade stops were too widely spaced for the cutting edge. Maybe there was more than one type of 1914?
