Check your Amazon History!! It will have most of your orders. Better than trying to keep all the paperwork for a year.

Every time I replace my rotary blade, I think to myself "I need to do this more often!"

When I bought replacement Olfa blades on Amazon, I noticed the packaging was all in Chinese - except for the word "Olfa." So, next time I went straight to the source and bought them from Aliexpress for about half the cost. As much as I hate to throw away the dull blades and would like to find a quick, easy and economical way to recycle them, I suspect it would cost more than just buying more blades.

I've never had a sharpener because all I heard were negatives. If you shop around you can get blades at a very reasonable price.
Welcome to the board :)

[QUOTE=grammasharon;7958697]I tried several different packages from Harbor Freight and could not get any of them to work. I buy all my blades on Amazon for very reasonable prices and so far after 3 different shipments and 3 different distributors have not had an issue with any of them. In fact this last pack I got just don't seem to get dull. Wish I would have paid closer attention to where I ordered them from.[/QUOTE]

If you go to Amazon and look at your previous orders, you can find where you ordered them from! If the blades are as good as you say, please share the source when you find it! I agree about Harbor Freight - some people seem to get luck, but not me.

I have honestly not tried any blade sharpeners, so really can't say. I usually get the replacement blades either with a coupon from JAF or at walmart.

I've tried them and was not happy with the results. But, I found some blades at Amazon that only cost $10.99. They work well and are extremely cheap, here is the link.

Good luck

I haven't had good luck with Harbor Freight blades. Some were dull right out of the package and others dulled very quickly. I like name brands a lot more.
