This is an old topic but finally was able to get to Harbor Freight and bought "45mm replacement blades" for my Fiskar Rotary cutter. They are sold as "replacement carpet cutter blades" # 97642, $1.49 for a pkg of 2. I was to cheap to pay the shipping and knew I would be going to Spokane so waited. Actually sent my husband in and he bought 4 pkgs.
Not sure who first mentioned these but THANK YOU and to all the newbies, this is a GREAT buy.

:thumbup:

Just returned from visiting my daughter and Harbor Freight was a stop for us. Haven't needed a blade yet but am now prepared. :)

Yes, and they are great to use!

My DH was so shock that I ask to go to Harbor Freight. just gave me the look !!! when I told him what I needed

Just don't do like I did & buy 10 packages...and then realize that I have a 60mm rotary cutter not a 45mm rotary cutter LOL

OOPS! :)
Would they not let you exchange for the correct size?

No, they only make one size for the carpet cutting blades unfortunately. Hopefully they let her return them.

Or maybe it's a good time to invest in a 45mm cutter?

I was very disapointed when I went they were out of blades. Would have 32 pkgs next day. We live about 60 miles from Tulsa so I won't be back for a while.

Great information. thanks
