On 1st use... too dangerous to even have in the home... something that Jams on 1st use is obviously poorly designed... I doubt it is approved by any regulator body BEWARE

blade stucked inside, button also got sutcked, can not push the blade out.

No replacement blades. Description says "4 replacement blades." That is false.

Blade mechanism gets stuck even with wd40

Although there are no instructions included to change the blade I assume it’s was every other utility knife blade and reading the Q&A it is. How are you cannot get the blade to fully engaged so it’s unusable once you change from the 1st it came with!

We're all opening a lot of boxes now. This is the knife that makes it easy to do. Love it. Don't love it any longer..cannot change blade

The red release button broke right off the first time I pushed it in to replace the original blade. Worthless now.
