I just put my used blades back into the container they came in. I take a sharpie and put a big black X across the used ones. I use them to cut other stuff besides fabric, like paper, wallpaper, tool box liner etc. Eventually I tape it shut and throw it away. I will have to check the website out.
Jcrow I agree with you. SOme things you just need to buy good quality. My sister always buys the cheapest she can and then complains when it isn't good quality. I do have some things where I know I won't use it much or for very long and the cheap stuff is fine. But for most things I try to buy the best I can afford. I just feel that you mostly get what you paid for.
