Has anyone ever bought a rotary cutter blade sharpener? Do they work? Are they worth the investment?

I have one and use it fairly regularly. It does extend the length of blade use, particularly if you switcht the blade to the other side. Not sure I'd buy it again though because it is hard to get "dead spots" out of the blade sometimes.

I got mine with a 50% off coupon at Joanns and then found one for the bigger blades on the markdown - so for what I paid for them, yes, they were worth it...
just be careful not to cut yourself (ask me how I know)

There have been a lot of mixed reviews on these... it is on my list though :D:D:D

I've been wondering about this subject also. I figure it would be worth it to invest if for no other reason than to get a few more cuts out of each blade. Sort of the same principle for sharpening knives isn't it? On my list of wants also. :D

I've got one and it does extend the blade a little.

Just be careful, 5 stitches and no sewing for a week tells my story!!

on my list too.

Yep -- I've put it on my "wish" list too....

They have such mixed reviews I decided to wait on one.

Hmmm. I never saw any mixed reviews. And I don't remember mine being all that expensive.

I like the sharpener. I have one I bought from connecting threads (I think) It's manual and cost ten bucks. I use it frequently, like honing up a knife.

I have one and I find it medicore at best. It sharpens the blade for a little bit, but, still find a few places it misses. Not worth the money

I have one and think found it to be pretty useless. The sharpened edge does not hold long, dead spots still remain and they are expensive. I take my blades to a professional knife sharpener. He hones the blades thus they are much sharper than when new. He charges only $2/ blade. Check your yellow pages.

Sorry to say I have one. I do not like it. To me they are worthless.

Yes and no not worth the money or trouble :cry:

I didn't realize a knife sharpener could work on them. Thanks for the tip. That is what I will do.

I use my super dull ones or ones with dead spots to cut paper.

I have a cheap blue one fron Joanns. It helps but not like new and you do have to twist it alot of times and turn the blade over and twist alot again.

I've been wondering about them too, I think maybe I'll just buy a couple of new blades.

What do you look under in the yellow pages? I'd be willing to check that out rather than spend about $20 on something that doesn't work well.

I have not tried them, I just buy new ones, but if they work that would be wonderful!
