I've had this blade now for a little over a year and i flipped the clip to the right side and carry it in my work pants right side front pocket. I can deploy the blade with a flip of the wrist and be ready for slicing. You do have to use 2 hands to close and lock. The blade has stayed sharp and all the screws have stayed tight. Very handy small blade

awesome knife.
Josh V. on Mar 28, 2015

I have the combat ready version of this knife so results may vary. Well, it's more karambit than balisong, it opens like a balisong but performs like a karambit, certainly not a flipper, you're lucky if you can get a rollover out of this knife, of course if you're not buying it for balisong flipping then ignore that, now if one does karambit manipulation and maneuvers then you're gonna be fine, I almost wouldn't know this wasn't a normal karambit, the pocket clip is great, no problems at all, the latch is ok, it's just hard to close it one handed, this knife will easily do very basic balisong techniques but nothing more, this knife is about 80% karambit and 20% balisong but overall it's an awesome knife.

Not bad
Sterling D. on May 10, 2022

I've had this knife fir 2 years now as my EDC work knife, so think I have a pretty good understanding and knowledge about it at this point. Opening it took a little getting use to but once I got the hang of it one handed flipping is not a problem. So after 2 years here is my good and bad list. The Bad: 1> The latch that holds it closed is a bit weak, a little pressure to the belt clip is enough to pop it open. This happens frequently enough I find myself reaching back from time to time to make sure it's still closed. 2> After a bit more then a year the spring that forces the latching mechanism to swing around to latch it open broke, so I now have to manually flip it to lock it in place. The Good: 1> Other then the spring I mentioned above, decent quality. All the screws are still as tight as they were the day it arrived. 2> Belt clip is still not only intact but holds the knife firmly in place. I can not say this about to many knives as most of them break after a few months of constant use. 3> Stays sharp with minimal maintenance, I run it across a steal every few days otherwise the edge holds up well to daily use. 4> Concealed in plain sight. Looks enough like a multi-tool I have lost count of how many times I have been asked to borrow my pliers. Overall 4/5, if not for the broken spring one year in I would give it a 5/5. Check your laws before carrying it though, it may not be legal in your locality, I live on a state line, one side it is legal to carry as long as it is not concealed, otherside it is illegal to even possess. (considered a butterfly)

Was underwhelmed
Tyler I. on Aug 8, 2018

I was looking for a karambit for my collection and I saw this unique blade. While it looks nice and has a different opening method, it just didn’t fit me. I tried to get a motion down to open it in one go but I never could get it. And with the closing it with two hands thing, I didn’t like it. On top of that I felt like it wasn’t worth what I paid for it, it just felt cheap!

Good display knife
Wendell H. on Dec 29, 2017

I bought the Vuja De knife before Christmas. I love the look and concept of this knife. But I found it very difficult to use it like a balisong due to alignment issues with the locking mechanism to secure the blade open. Not practical for using a 1 hand opening technique.
