NT Cutter 9mm Snap-Off Extra-Sharp Precision Blades, 30 Degree, Black, 10-Blade/Pack, 1 Pack (BA15P)

Up to 5× longer-lasting and genuinely extra-sharp. The 30° blades handle slightly thicker materials well since you can safely extend another notch or two. When cutting 3/16" high-density spun polyethylene boards, they outlasted disposable plastic knives by a wide margin. The size fits standard 9 mm knives for easy insertion, but they’re not meant for plastic disposable handles. As with any knife, safety is your responsibility. I rarely leave reviews — this is an easy recommendation.

Good quality

This is exactly what I had in Japan before, very sharp with 30 degree and black blade. High quality for the blades definitely! high recommend to people who needs to create architecture models or artworks when cutting numerous materials and need to keep the blades sharp.

I used these extensively for installing PPF and vinyl wrap on vehicles. They are orders of magnitude sharper than the regular stainless blades. You must be careful not to cut too deep and don't trim tint on the glass like with the normal blades. These WILL score the glass. These are more expensive, but they cut so much smoother and more easily. I won't install wraps without them.

I purchased the black extra sharp. These are so sharp I think you could cut off a finger and not even know it. I want these on hand at all times.

Great quality. Ive used olfa 30deg blades, but heard these are also nice. I also ordered the standard NT blades. These super sharps have a longer edge taper than the standard, both are sharp AF. Ill use these for delicate jobs and thw normals for reg use. Top notch japanese quality.

Omg I am in love with these blades. I can’t believe how sharp they are. I bought them for clean cuts of vinyl wrap for a car. If only I had these when I started it would be so much cleaner. So far, I’m having so much fun I’ve cut half the stuff in my office. Lol. Paper, stickers, you name it. Just find myself playing with them on calls (Don’t play with knives). And… I’m still on the same blade and haven’t even snapped off the first section yet. First time in a while a product lived up to the performance desire. Very cool.

As the title, wish I knew it sooner in my life. No more exacto, this is much sharper, tougher and 1000x more durable.
