I do it too. When I get to the "sawing" point, I'll change them!

I am guilty of the same thing.

i had one and it does work really well. I stopped sewing for a year after we moved and lost it and I miss it :( I always feel like it's a waste to throw it away when I know it could be like new again with one of those. I used to get like 4 sharpenings out of each blade! I used to sew and sell alot of cloth diapers and each diaper had like 8 layers so it was alot of cutting :)

Hahaha... I do and feel the same thing!

I am often wondering abut the blade, and I admit, the sewing machine needle, I hate to change, it's just so small and in a small space...my hands get all tangeled up...

I use the sharpener. It's so much easier when the blade is sharp.

Change blades way oftener now that I found the Harbor Freight carpet cutter replacement blades. They are around $1 a blade instead of the $8-$9 of regular blades. I don't know if they work in all cutters, but they do in the Martelli cutter.

It's like changing sewing machine needles
It feels so good when you finally do

guilty guilty guilty

Saw a great sign in a quilt shop: "Replacing your blade is like buying a new bra- you hate to spend the money but are much happier once you do!"
