## Customer Reviews

### ⭐⭐⭐⭐⭐ Secondary lock mechanism
*by P***R on March 17, 2024*

Excellent carry and user knife. Has a secondary safety switch which really sets it apart from every other folder. You can use it like a fixed blade with no worries.

### ⭐⭐⭐⭐⭐ Great Value
*by D***E on March 20, 2021*

Great utility knife for the price and very sharp blade

### ⭐⭐⭐⭐ A very solid knife
*by C***D on December 3, 2021*

This is actually an *excellent* knife for the money. About the only con I can think of are the screws that hold the handle (actually the entire knife) together are "star-faced" and extremely difficult to tighten (I've never found a screwdriver with a head to match) when they come loose. And they do loosen eventually. Other than that small drawback, great knife!
