The NT Stainless Blades (50-pack) are a shop standard—whether you swear by NT or fly the Olfa flag.These 9mm snap-off blades are stainless steel, ultra-precise, and built to glide through film like butter. They’re the go-to for installers running the NT Red Dot Knife, but they’ll fit any 9mm snap knife with a solid lock.Some installers argue NT. Others swear by Olfa. The truth? They’re both made from the same metal, same number of snap segments, same razor-sharp edge.But here’s the kicker: NT blades usually cost a couple bucks less. So if you’re cutting film all day, it’s hard to ignore the value.
