Question: Can you replace the LED light/is there a battery? Mine has stopped working.
Document: Basically, as described.LED light stopped working almost immediately after receipt. Yes, I changed the batteries. Still didn't work.Locking blade kind of locks. Sometimes yes, Sometimes no. So, that could be a hazard.
The LED button is too easily activated while stored in its carry case resulting in a dead battery. The knife is sharp, window punch works well along with the seat belt cutter.
I just received the knife in the mail today and it looks great but the LED light is not functioning.
It's possible that you could end up with a dead battery just at the time you need it most. The light switch is why I knocked a star off my review.
Good quality put all functions did not work. The LED light did not work. I would have returned it but I have a flashlight In the car..
Hope I never need it to shatter a window, but it will do the job. Only down fall is the LED light. Too easy to leave on if you bump it, even in it's case. But that is really a minor thing.
I'm a Fire/Medic so tools like this can be useful while at work. I have had it for a couple months then the light which was already very dim went out. It was so dim i did not worry about getting a new battery for it. A few months later the window punch broke. I use it sparingly mainly for the seat belt cutter and the knife so I am not sure why these two things failed.
So what was the belt clip broke a few days ago after a few months of carrying it every day. It was my true multi-tool knife. I used it so much the little light battery died. Now I need to decide if I want to buy another one or try to find tiny screws that will work. I got so use to it that my Boker knife feels like a useless knife when I was force to put on another knife to wear. For the price, it is worth everything.
Overall, good value for money, just forget about the LED that you probably would never use anyway.
The battery for the flashlight died after a couple days. I dont like where the on/off button is located on the knife&#62; It can easily turn on accidentally while in the holder or out of the holder without you knowing its on..
Answer: yes
