I have to say that the consistency of MOST of Harbor FREIGHT TOOLS is far from Stellar. They are cheaply made tools that are offered at a fraction of the price for good reason. I honestly wouldn't buy their blades at all. I only buy blades at JoAnns using my 50% of coupon or stock up on them when their 50% sale is. Also, I must say that there are so very good sharpeners out there that allow you to get maximum use out of your blades. I have 3 types and have found one to be superior.
