18mm Snap-off Blades, 50-Pack, Quality Black Carbon Steel Made, Sharp and Durable, Heavy-duty Replacement Blade for 18mm Box Cutter and Utility Knife

I love these blades. Sharper then all pro blades but damn, they are thicker then all pro blades to. Also they are slightly wider for the k5 knives or whatever but I highly recommend yiu get these.

The blades are very sharp and finite. I predominately use these blades for wallpaper. Very, very good item and will definitely buy again. Could easily cut card board boxes, vinyl wallpaper, grasscloth wallpaper, & other related materials. Happy client here

These are by far the sharpest and strongest snap blades I have ever bought. Recently used them in various ways to help me remove and install a patio door. The blades worked well to cut off the nail fins, trim off protrusions in the door frame, cut off painter's tape, and so on. Durable, strong, and sharp.I've learned that using a high-end utility knife with a wheel lock is essential to doing the job right.Amazon no longer sells the knife I use but the OLFA 18mm Heavy-Duty Utility Knife (L-5) is similar.

I use these to cut leather in my leather shop. Cannot tell you how important it is to always use a sharp blade when cuttin leather. I usually snap off the tip just before starting a new project to ensure a sharp cutting edge to cut out projects. Cuts through 10 ounce leather like a hot knife through butter!

These are much better than the other brands that I have tried, these at least stay sharp no matter what I’ve cutting

Excellent value for the money for 18mm snap blade refills, and so many for a low price. Great purchase!

Great for cutting rugs
