Review on WA Portman 45mm Rotary Cutter and Blade Set - Safety Lock - 5 Premium SKS-7 Steel Blades - Ideal for Fabric Quilting, Sewing, Paper, and Scrapbooking - Ultimate Rotary Tool Set by Doris Tran

Just received this knife and already love it. This is the third cutting set I've owned but my favorite so far. On the first set, I developed a bad habit of applying pressure to the blade with my index finger while cutting. The second set alerted me to this habit (too often) because it had no guard over the blade tip and after a few cuts on my finger I still had to actively remember not to stretch my finger over the tip. That's not a problem with this blade, not only because it has wonderful protection at the top, but it also automatically retracts the blade when I let go of it! I love it!
