Amazingly sharp. Considerably sharper than standard Olfa blades. These don't cut so much as glide through. Well worth the money.

The best! Sharp as can be.

I love this. Every time I tear into a new piece of foam core it fills me with joy. The black edition definitely cuts for longer. It stays sharp for more cuts, and is just amazing to look at. If you are one of the few people who get pleasure from getting clean cuts, you'll want to have this in your life. Now. I barely use any other blades/cutters. No flimsy exacto knife #2 for me. No 10000 little blades to buy.This blade and the olfa holders gives unexpectedly clean/easy cuts that are VERY precise. Once you master this in your hands, you'll save a lot more time just cutting with this, instead of switching out blades all the time.I am an art student and dependable/sharp blades for clean cuts is VERY important to me. I wish I knew of this blade/knife combo when I first started my art education, instead of in the middle of it. A++++++ all the way. Get it. Feel the power.If I could, I would cuddle next to my blades.But the student loans are stabby enough.

Packaged well and priced right compared to the small package at the big box hardware stores...I checked!

very useful

I use utility knives like...I dunno every day. I wear pants and have a pocket specifically for knives because I need knives at work. I bring a utility knife with me everywhere. I gave up on the utility knives because of expensive blades and constant changing of blades. These blades last a very long time and to change them I just snap off the dull piece.Im never going back to Stanley knives and blades.

Love the Olfa knives and these blades are extra sharp. So much better than the run of the mill utility knives. Get an Olfa knife and pair it with these blades.
