Has anyone used these? They sound like a good idea - sharpen your rotary blade as you cut - but I'd like to know if anyone's had luck with them before I invest in any more rulers.

My personal opinion is run away from them. I ruined 2 blades they do not work like they say. I purchased a small one and will never use it again!

oh wow! :shock: glad somebody asked. I'll wait till they work the kinks out before purchasing!

Not getting the best reviews on here... :(

LQS will not be carrying them after receiving demo items and they were horrible. She said that as it sharpened the blade, the shavings became embedded into the fabric.

OUCH :cry:

Someone needs to come up with a sharpener that really works.

I agree whole-heartedly! Those little suckers are expensive, but... :roll:

I bought it because it is 37" long and not for the sharpening. Guess I will have to use the undiamond side.

I use the True Cute Blade Sharpener from Grace, but I bought mine at Quilt in a Day.com

If you use it correctly it works well. Even tho it's expensive the money I save from not buying new blades more than pays for the $40 I spent on the sharpener. I think I'll be sure to wipe off the blade before cutting fabric to take care of the shavings. I didn't even think about that.

I figure it's the same when my DH sharpens our kitchen knives. Don't really want shavings in the food!
