this review title is: good sharp blades but get dull quickly and the content is: these blades do the job but are pretty much single use only at least for my application i use them to take off the dead scaly skin off my heels and after one session the blade is pretty much dead that might be a reasonable expectation though since the skin is very hard and rough.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
