### ⭐⭐⭐⭐ 







  
  
    Vigilante-approved
  

*by U***G on Reviewed in the United States on December 11, 2018*

Very sharp. Deducted a star because it's kinda tricky to open, especially when you're chasing criminals in the dark. (Although it's kinda heavy so if you threw it closed it could still knock someone out.)Also I tried to spin it and then catch it by the handle but hey there's now a cool scar on my hand. I'm not sure which side cut me and neither of the blades have fessed up yet, so be careful.

    Made me a superhero!!!
  

*by J***L on Reviewed in the United States on September 26, 2014*

This knife is awesome! It is all solid steel. No plastic on it. The blades open quickly and easily. Item is not bulky in my opinion as some other reviewers claimed. It reminds me of a Batarang, Wolverine's claws, or a set of brass knuckles with blades attached. It fits perfect to my fist so you can punch and cut all at once. Not too heavy, nor too light. Weighted just right. If you want to use just one blade at a time you can as well although it is built more for a fist with both out. I would recommend this to anyone looking for self defense knives. A extremely high quality knife.

### ⭐⭐⭐⭐⭐ 







  
  
    Well done!
  

*by M***. on Reviewed in the United States on May 22, 2015*

It's actually extremely well made for something that seems like a novelty knife, and for such a reasonable price! Other knives I've acquired for the same price have fall apart or broken by this point, gotten hooked on something or been very dull, etc, something wrong with it.But this thing is amazingly good quality and did not expect such quality from this knife!I also accidentally slammed it into the ground while trying to punch a box, with it, and it was completely undamaged afterward. Good craftsmanship. Tac Force has a new customer.
