hi
thought i would give them a go ,used one in a slant and it was not good, the hairs felt like they were being torn out. swapped the blade for another one.same experience . not wanting to waste the blades i put one in a gillette tech and tried again , felt much better did not pull half as much ,so now will use them for trimming up .used the other blade in a merkur 1904 and that was ok to use as well .
