I have an extra rotary cutter that is marked "for paper only" and I save the used blades for cutting cardboard, poster board, paper, and when the husband needs something cut in the garage (like a mat or rug) I have them ready. You can also trade them in for new ones. The company will give you credit for each blade (like about $3.00) and you pay for a new one (much cheaper than some of the quilting companies) and you are recycling the blades. I will check my notes and see if I can find the url for everyone. Here it is: http://www.lpsharp.com/

You can mail your blades to LP Sharp Company and you can exchange your old blades for new ones - must send at least 5 old blades and you can get new ones for $3.00 a blade. www.lpsharp.com. You can also buy blades for much less then retail even if you do not have trade-in. I have bought from this sight and they work pretty good- the blades you buy are re-sharpend. Check out the web site and they explain how to go about it.

I was real leery about the "True Sharp" Power Rotary Blade Sharpener and finally bought one. Well, I love it. It works so well. Wish I would have bought it sooner. I can make my blades last so much longer. I can tell it will save me $$$ in the long run. I usually have to change my blades out frequently, but now they last such a long time. No more buying a 5 pack. And for getting rid of the used ones...I just stick them back in their original containers and tape them up and throw them out...same as everyone else.

I have 3 - none work
Am told one needs to use before the blades go dull.

I too keep mine in a plastic container.
When it's full I tape it tightly closed and throw in garbage bag.

Couple times a year in Milwaukee we can take our paint and used motor oil and old electronics to a collection point at the fairgrounds. They also accept old medication because they don't want us to flush it. That's the time I get rid of my blades. I just figured they could be recycled.

i have one of those blade sharpeners and i love it i have been using the same blade for the last three months i use it till it starts to dull then i use my sharpener and off i go again good as new. i dont have the electric sharpener just the little manual one but i would not like to have to give it up. its been a money saver for me.

I take my used blades and needles and pins with me when I get my blood drawn and they are kind enough to dispose of them for me.

I'm still saving mine. One of these days, I'll invest in a sharpener.

I have never had much luck with the sharpeners. I tried the L.P. Sharp company and just got my first batch Saturday. They now replace your used ones with new ones. Great price and I feel better knowing the old ones are recycled.
