5.0 out of 5 stars Extra long, and strong.
Blades worked great cutting 2″ foil-faced polystyrene. Used 2 blades for 8 – 4 x8 sheets cut into 4 sections each. Probably could have done it with one.

4.0 out of 5 stars Not easy to find
Don’t know why but I never see these in the big box stores. They do come in handy but so far I have only found a limited number of sceneries for use.

5.0 out of 5 stars Use for cutting urethane around car windows
These are perfect for cutting windows out, a bit flexible and sturdy. The double length, makes it easy to get into spots standard length cannot. Used 4 blades to cut a frt and a back window out.

Dinged one star on value for money. I have two utility knives that use this longer blade which can be helpful in certain applications, but I try to use them sparingly because a regular utility knife blade is so much more disposable from a cost standpoint. If I could get a 100 count pack for a reasonable cost, I'd be 5 star.
