### ⭐⭐⭐⭐⭐ Came Hair shaving razor sharp
*by A***R on June 5, 2022*

Years ago when you bought knives(unless they're top tier blades), the biggest problem was that they came dull AF, and their quality was so so. Now all the blades I buy, tend to come standard hair shaving sharp.5 star for the function to cost rating: it fully locks into place with the assist. And comes with your standard locking mechanism for these type of pocket knives. And it came razor sharp.Quality: is a little sus. The handle feels like a styrofoam/plastic blend of material and in terms of weight, make this feel light as a feather, but feels like it can break easily under stress.I used locktite on all the screws so they dont loosen as a precautionary measure. The clip hangs on the knife at an angle so if you clip it to your belt or pants, it wont be hanging straight. At 5 dollars though, you can toss it around and not give AF if it breaks or goes missing. Planning to get a few extra as an EDC.

### ⭐⭐⭐⭐⭐ Probably the best knife you can get for the cost
*by M***S on May 6, 2025*

It’s surprisingly good, comes a little loose but is easy to tighten the screws and it looks great

### ⭐⭐⭐⭐⭐ As described
*by N***. on December 3, 2024*

The media could not be loaded. This knife seems to open easy and lock nice has a seatbelt cutter and a glass breaker the design feels really cool it has like a bumpy textured feel to it the belt clip is at an interesting angle but it doesn't feel weird in the hand or anything...
