The very first time I used this the blade stuck open and I cut my finger trying to move the button back down. It's not like I've never used a utility knife before either. Ridiculously low quality.
Needed a box cutter to cut out clouds from thick poster boards for my Girl Scout Bridging to decorate stage. I bought this one and I was very happy with the performance of the knife. It cut through the board smoothly and made the clouds look great. I would definitely buy this knife again.
Am finding that the blade does not always stay locked in position as I press down for a cut. Don't know if this is just the one I bought or indicative of the whole line. Otherwise works as I expected.
