NT Cutter 9mm Ex tra-Sharp Black Snap-Off Blades, 50-Blade/Pack, 1 Pack (BA-51P)

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.

I LOVE the 9mm, black carbon steel (58 deg) angle, precision snap razors. I got the pack of 50. I easily snapped off a perfect piece with a pair of needle nose pliers (I had a few pieces left from a cheaper brand snap razor and it did NOT snap evenly and would not fit into the holder well. So I ordered these to try). I actually used it to fix the thread cutter on my Husqvarna Viking Designer SE sewing machine. It fit perfectly and runs like a dream now. I didn't have to take it to a shop and pay who knows what fee to have it serviced and the 'blade' on Viking sites sell for about $26 for just the ONE blade. Knock off blades on Ebay sell for about $5.00 for ONE piece. I can replace my own blades now, whenever it starts to get dull...I have 49 more pieces and it only cost about $9.00 for the entire pack, free shipping with Prime. I'm in love. I sew alot and I am so happy with this product!

I’ve been ordering these blades for my workplace for the last few years. Most blades in my area are very expensive compared to these. I was surprised to find the quality in these blades are extremely good for the price! They work better than the blades my workplace provides! People around my workplace ask for one, and asks me where I get them since they work so much better! I’ve been buying these blades for many others at my workplace who don’t have amazon that prefer this product as well! If you’re looking for a nice sharp blade that is worth every penny, look no further!

Nice, sharp blades for a good price (about $9 in May 2024). Can't comment on durability yet. 50 pieces - I figure this should be close to a lifetime supply for me.

These are great value for the money, fit both, my Olfa brand and dewalt brand 9mm knifes perfectly. They are always extremely sharp but depending on what you cut, they dull faster then Home Depot’s Husky brand equivalents.

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

These worked in my cheap Anvil utility knife. No issues, easy to install and break when needed, and very sharp. Would definitely recommend and purchase again.

These are as sharp as they come. I've tried all brands and used them on many materials. Shocked at how sharp these are considering they are much less expensive than Olfa (which are still top-notch as well). [FYI tip: how to test truly crazy-sharp edges like these? Simple. When u sweep the blade through the hairs on your arm (without ever touching your skin, passing just 1/4" above it), does the blade catch a little on the hairs? Japanese swordsmen would do the same with a sword, except with the hair at the back of their head.]
