Sharp and long-lasting
Nine edges per blade is no joke. I've been breaking off segments for weeks and every fresh edge is just as sharp as the first. Great for breaking down cardboard boxes.

Good blades for the price
They cut vinyl and wallpaper cleanly. Not quite as razor-sharp as some premium blades but more than adequate for everyday work.

Warehouse work approved
I go through utility blades fast at work — cutting corrugate, shrink wrap, tape, you name it. These snap-off blades save me so much time because I don't have to stop and swap blades constantly. One blade lasts me through multiple shifts, and the ten-pack keeps my toolbox stocked for months. The alloy steel definitely holds an edge better than the cheap hardware store packs I used before.

Fine but nothing special
They work and they fit my medium-duty knife. I've used sharper blades for detailed cutting, but for cardboard and general tasks these do the job. Probably would buy again if on sale.

The only blades I buy
My dad introduced me to OLFA decades ago and I've never switched. These silver medium-duty blades are consistent — no burrs, no snapping crooked, no dull spots. For wallpaper especially, a clean sharp edge makes all the difference between a smooth cut and a torn mess.

Snap cleanly, cut well
The snap-off segments break off cleanly without the little tails some blades leave. Held up fine cutting through double-layer cardboard. Would recommend.

Two blades felt dull
Most of the pack is fine, but two of the ten had noticeably dull edges right out of the wrapper. The rest cut well, so maybe a quality control issue. Docking stars because I expected better consistency from this brand.

Nine edges, can't beat it
Best value in blades. Each segment stays sharp through heavy use and snapping them off is easy and safe.
