How to Sharpen Your Rotary Blades. Have you tried this?

I saw this tip on Pinterest the other day from a blog called Pennys Hands.  Sharpen your rotary blades by cutting through tin foil.  Being the type of person who can't throw anything away that might someday be useful ( my sister says I verge on hoarding) I had 10 old dull rotary blades in a plastic case in my sewing cabinet.  I set up an old ruined rotary mat, (yes I saved this too) and turned it over onto the back since I didn't know if this process would damage the mat at all.  I tore off a large piece of tin foil and folded it several times.







Then I cut through the tin foil in tiny, tiny strips.  Let's be realistic here, tin foil is much cheaper to buy than a trip to the emergency room so be very careful to not cut your finger off while making these thin cuts in the foil. Keep your fingers well out of range of the rotary cutter.  I can't be held responsible for any injuries you may sustain in attempting this dangerous feat.

This is what your foil will look like afterwards.  I wasn't sure if this would be enough to sharpen the blade so I turned the mat sideways and cut through the foil strips again.
Then I tried the sharpened  blade out on some fabic and batting.  It seems to have worked really well.  I folded the fabric and cut through several layers just fine.  I had nicks in some of the blades and it seems to have taken them out too.
I'm sure they are not as sharp as a brand new blade and I don't know how long they will last but I think it was worth trying.

  1. I've had good luck with this tip. I can get by without replacing the blade for quite a while.

  2. Thank you for posting this. My current blade is getting a bit dull and I really don't want to spend money on a new one right now. I'll try this before my next quilting session.

  10. I tried this using one sheet of foil folded. And used an old cutting mat. I sliced and sliced and sliced until I had something resembling confetti. And guess what? My blade was sharp again.

    Thanks so much.
