Best utility knife blades for light duty uses as the will snap with too much force

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.

Very sharp and stay sharp. They’re brittle and may break if flexed. I use mine for opening boxes and cutting cords. If you’re using it for other stuff—don’t—unless you’re prepared to replace. If all you do is snap off the tip, just turn it around in blade holder. Voila! Not cheap, but worth it to me.

Really sharp, long lasting, way too expensive

Blades were as described. Just be aware, they are very brittle. They are super sharp, and do hold their edge longer than the steel blades, but they typically break before they start to get dull enough to be replaced.

Great little well made razor knife

Sharp clean

Nice

Exactly what I was looking for. Beats the steel blades. Retains sharpness longer, more corrosion resistant. Good quality
