Starrett Hidden Edge Utility Knife with Easy to Use Safety Lock and Level for Fast, Tool-Free Blade Changes - Retractable Lever Action, Aluminum Case Material - S011

I hate that we are forced to use such a device for work, but these are about the best thing I can find for a safety rated cutter.

This knife works exactly as described. It operates smoothly, and adjusts cutting depth easily. Durability seems to be great as well. The blade is held very securely in place so it will not rattle around when cutting with it.

Too much safety, I didn't like that I had to depress the lock thing on the bottom to expose the blade (over kill) so i removed it, and now satisfied.

Love the squeeze blade, and knife works wonderfully until the button to change the blade pops off. Then it is unusable.

This is the way to go if your looking for a solid products! Slices and dices!

I am the maintenance supervisor for a industrial manufacturing company. We wanted to be proactive with safety and after testing a few knives, our operators decided on this model. It is not as safe as the "auto blade retract" which work off of pressure. This knife is better than having an open blade, exposed all the time, which is what we had before. My operators have used it for a week (80hrs of use) and we have had no issues.

First, let me say this: I pack freight for a living. I use a utility knife constantly at work and have for years. I also use them a lot at home. I've used most types of utility knives and owned lots. This knife was based on a great idea. The blade comes out quickly and easily, and retracts automatically. Unfortunately, it suffers from a fatal, but common flaw, namely cheap construction. It's made primarily of plastic with a bit of aluminum and steel worked in. The plastic is durable enough, but the steel catch for the door where spare blades are stored in the handle is flimsy. In regular use, the catch sometimes opens when you don't want it to. This jams up the knife, so that it won't open or close. It's easy to un-jam it, but it will happen again. Bottom line: There are better utility knives for less money.
