These are the best replacement utility blades I have found on the market and are part of the reason I was interested in Fiskars in the first place. They will work with any utility knife, and Fiskars claims they will last up to 24 times longer thanks to their unique carbon-bonding process. That sounds like a lot of marketing talk, but after using them, I wouldn't be surprised if it were true.

Utility blades always come in handy, so I would recommend picking up a couple of packs of these to replace all of the utility blades you have now.
