3M Hand Masker Film Blade, Fits M3000 Dispenser, Delivers a Straight Cut with Durable & Sharp Stainless Steel Blade, 12 Inch Blade, Designed to Cut Masking Film & Paper (FB12-SC)

I started with the blade that you can buy at the local big box store. That thing was useless! It flexed way too much so cutting plastic with it one handed was rage inducing! I hold the plastic to the wall with one hand and so only had one hand available to hold the masking tool. The basic blade flexes WAY too much to work one handed.So I returned that and ordered this one. That was the way to go! Since this one is anchored in 2 places it actually works. I am still not very proficient with it, but no more swear-fests when trying to use it.Frankly, 3M should stop selling the other version and only sell this one. It's the same price and this one works. The other one only hurts their reputation.

This is by far one of the best tools I think I've ever bought! Definitely worth the couple extra dollars for the stability. And the straight cuts.. makes the job so much faster! What are you waiting for??

So convenient and flows easily along and space.

Okay this thing performs great I love it really sharp cuts the film way better than the standard one that it comes with but holy crap it's expensive it's kind of worth it I would buy it again but I'm angry that this stupid thing cost so much.

Used this with the 3m M3000. Together it made the job of spray painting the kitchen and exterior of house so much easier

This is a great improvement to the masker when cutting film. Straight and easy to cut.

La he ocupado poco, pero bien....

This blade and the m3000 dispenser are well built and obviously quality tools. Unless you are a professional painter familiar with the m3000 series, you may find it too diffucult to use effectively. Alternatively, you could spend a lot of time and wasted material learning to use it. I went back to tape and cardboard. I did watch the videos before buying, but actual experience is different from watching a video.
