## Customer Reviews

### ⭐⭐⭐⭐⭐ Super sharp and worth it.
*by S***. on June 14, 2025*

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.

### ⭐⭐⭐⭐⭐ Great quality
*by C***R on December 19, 2024*

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

### ⭐⭐⭐⭐⭐ Perfect utility knife for many projects.
*by W***H on May 1, 2023*

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.
