In the sewing and especially the quilting world, there's always some great new gadget that is supposed to save you time or money. Most often, they hardly get used once you get them home or they don't work as advertised. This rotary cutter sharpener I bought about 10 years ago is a different story entirely. I was just sharpening the blade - probably for the 50th time in the last 10 years .... and I was thinking what a good investment this sharpener was. New blades are a whopping $5-10 each ... but I haven't bought one in over 10 years. Yes, you read that right, Ive been resharpening the same two blades for 10 years. I have one I use for paper and one for fabric. Now, I used to spend over $100 a year on blades. Since I bought this sharpener,  I've bought a new sanding disc once or twice at about $8 each time. The sharpener was about $15 to begin with. Let's do the math ... over $1,000 in those 10 years compared to $31. That's over $900 I can spend on something better ... like fabric!

All in all, a GREAT money saving investment for anyone who uses a rotary cutter.

Here's an article on how to use the sharpener.
