100PCS 9mm Snap-off Replacement Blades 30 Degree SK5 Black Blades for 9mm Universal Art Knife for Wallpaper, Paper, Eyebrow Pencil, Crafts

I loves these, i use them at my job and they’re awesome!! Ive bought the 100 pack for like 20. They last super long, theyre really sharp which is the best part bc it makes my job easier, other blades ive tried dont last long enough, I constantly have to change out the blade, but these are the best ive tried and im sad because they’re unavailable at the moment :( i cant find another pack this good

These are too good! They are sharper than any other 9mm box cutter I've ever used. Just have to be careful not to cut yourself because these cutter are razor sharp. More than any other brands I've ever used. HIGHLY RECOMMENDED!!

These blades are very sharp and have supportive metal along the blade. Very good product.

Purchased the 5pk. Very sharp. Decent in the hand. Inexpensive enough to buy a few to spread around workbenchs and appear to be rigid enough for detail work. Blade lock is a bit suspect, but have held up so far. Like I said, decent value and would purchase again.

These boxcutters work great! I have to use them every day for 12 hours and they work really well! Very satisfied

I use these all day long at work. I have had several others maybe even in the double digits and they all broke or wore out within 3 months of using. You get five knives with very very sharp very pointed blades. The only reason more than one has been used in my purchase is because I misplaced them 😅 couldn't recommend a product more!

I was so delighted at how well these knives work and how sturdy they are. The grip is excellent. The angle makes all the difference in the world! The fact that the darker blade matches the black handles is an aesthetic bonus.

These snap-off utility blades look nice and are extremely sharp right out of the packaging. I used these to trim some vehicle vinyl wrap and it just glides through the vinyl like a hot knife through butter. The 30 degree tip makes it easy to maneuver as well. The sharp tip makes the blade feel much easier to use and position as well.
