I have left mine in past the sharpening life of it. Some blades son't seem to last long at all. Others seem to last forever.

yup... the Grace one is the one I have... I LOVE IT!!!

I am guilty of this as well. Every time I change blades I say the same thing.. "why did I wait so long". I know its partially because it not an overnight thing.. the dullness creeps .. and I forget what I pleasure a new sharp blade is to work with.

grace company has a blade sharpener that you just run the blade though ...not even have to take it out of handle ....worth the money at the price of blades ...also your local harbor freight has blades for a carpet cutter [can order on line] that fit the 45 cutter way better price than other places

Lol. I love this. I really do think this about tires! Drives my hubby crazy!

I tried the sharpening too and it was worthless. I've talked to others who liked it. Perhaps operator error. Over the weekend I got an Accuquilt Go cutter. Problems solved.

I bought the electric TrueSharp Power Rotary Blade Sharpener (Amazon now has a good deal on it with free shipping) and it works. Guess what, though, I have not had to use it a lot because I got this rotary cutting matt at a quilt show as a show special. The Big Mat by Sewingemporium.com has a 5 year warranty and the surface is very smooth. There is actually less wear and tear on the blades. A rough cutting mat such as the one sold by Joann Fabrics (it is white and the surface is not smooth at all) can make rotary blades very dull in no time at all. I learned this the hard way.

I'm the same way with needles too.

I ave the Grace Sharpener and absolutely love it!

I like this idea of writing the start date on the blade but seems I tried it a while ago and couldn't get the date to last - even used a Sharpie marker. What do you use?
