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.
