NT Cutter 9mm Snap-Off Precision Blades, 30 Degree Blades, 50-Blade/Pack, 1 Pack (BD-50P) - Silver Color

I only used one so far but it was sharp.

I've been buying the same blades for years. They have served me well at work. I've never had a dull blade out of the pack, they hold up surprisingly well and are easy to snap off. Can't say I have ever broken a blade while working but the sections snap with ease unlike some blades out there

I've been installing PPF for Crystal Shield for 17 years now. I greatly rely on quality blades for my installations especially when I cut on paint to score and tear the film. Have been using Olfa 30 degree and noticed that only the 2nd blade section was premium and the 1st, 3rd, 4th and 5th were not as good. I'm happy to report that these blades are twice as good as the Olfa blade. Do yourself a favor and get these better blades at a much better price!

Packed tightly so blades stay nice and sharp when they get to you.

Sharp blades !

I am not using them in a wet environment so stainless is unnecessary. Again, these were a direct recommendation by Adam Savage on his YouTube channel. He should know as he has spent 1000s of hours working with foam, plastic sheets etc in his former profession and current hobby. Nothing beats the combination of price and quality for the sheer number of extremely sharp long lasting cutting edges. I find they are strong and flex, have never broke one on accident and I have no problem snapping the end because I line up a single blade and use a pair of flat nose pliers (duck bills') to break them off at the perfect angle.Unable to create a review for totally different item purchased in the same listing. So, I have also included photos of NT Cutter 9mm Snap-Off Extra-Sharp Precision Blades, 30 Degree, Black, 10-Blade/Pack, 1 Pack (BA15P), and the thin precision NT Cutter PRO Auto-Lock Stainless Steel Graphic Knife (AD-2P) they fit.

Extremely sharp. Sharper than the high-carbon version, as the cutting angle is narrower. Just keep in mind that they have a slightly greater propensity to dull.Very similar cutting experience to a scalpel, but you get to just snap off a blade whenever you want for a fresh one. If you have a strop, when these get dull you can strop it back to new with just a few seconds if you want 2x the life from it.Packaging was great, well-thought out, and sealed to protect from rust (even though it's a stainless blade.) It's the kind of consideration and high-quality finish you'd expect from something much, much more expensive than this.Amazing value, like that the seller hasn't tampered with the original packaging like whomever shipped my previous NT cutter blades did.(If you have a 9mm knife, and you just want the blades, these will fit that, and I highly recommend getting them.)Sounds odd raving about snap-off knife blades, but I use a knife like this for several hours a day doing high-quality finishing work as well as heavy cutting, and it's literally changed my work for the better. I've never used a better snap off blade - including the 'extra sharp' version of 9mm blades, which, in my opinion, are just easier to snap the tip off of because they're too hard and brittle).Hope this helps any of you that are about to drop 3x the price on olfa. Buy these, they're better.

Its a grate element for a hobbist.
