## Description

OKNIFE SK5 Utility Knife Blades– Experience superior cutting performance with blades crafted from durable SK5 steel, known for its exceptional sharpness and precision. These blades offer effortless cutting across a range of tasks, from heavy-duty applications to intricate projects. Designed for both professionals and DIY enthusiasts, each blade delivers reliable performance and durability, ensuring you tackle every job with ease.

Review: Worth the extra money - So much better than steel blades, they stay sharp longer than steel and have less drag through objects. I cut a lot of rubber, foam, and cardboard. They cut like a laser beam.
Review: Sharper than most ceramic blades - Ceramic blades are useful not because they are sharp, but because they do not dull, or dull very slowly. Most ceramic blades are not actually all that sharp (compared to a well sharpened steel blade), but stay moderately sharp for a really long time. These blades are actually really sharp. I saw a video review that called these out as much sharper than other ceramic utility blades, and that review was correct. You obviously cannot expect these blades to last when used to cut things that will chip the edge. I'm using them mostly to cut cardboard, and for that they're excellent. Some had suggested that these blades were too thick to fit in some holders. I haven't had a problem, and I measure their thickness as a few ten-thousands of an inch thinner than general purpose Milwaukee utility blades and about 5 thousandths thinner than Stanley hook blades.
