Great Knife!

 Rated 5.0 stars

From JVP


This is my second 5.11 knife and I love it. It's super-tough and super sharp. It's very easy to open with either hand (I'm a lefty) and I'm very impressed with the build quality. I know it'll last for many years.

Excellent Utility Knife

From IfIToldYouYoudHaveToDie

I love this knife. The Sheepsfoot Point is perfect incase there is glass harder to break that bounces back. A Tanto point would risk stabbing yourself, the Sheepsfoot prevents it. The Sheepsfoot also keeps the blade down to ensure sharpness. The Carbite Tip was a pocket shredder until I moved the clip so that the Carbite Tip was out of my pocket while equipped. Which makes the ambidextrous pocket clip a great feature. All around great product.

Too Thick

Sheepfoot point is useless, so I ground it into a Tanto point. Glass breaker is a pocket shredder. Belt cutter blade makes knife twice as thick/heavy as it needs to be. Will sell/trade/modify or give away at first opportunity.

This knife is by far the best rescue knife I have ever owned. I really like the dual blade/seat belt cutter attachment with the actual working window punch. The pocket clip that is customizeable for the user is a great feature. Out of the box, I did not like how the clip was placed on in the factory. With taking out three little screws, I was able to put the clip where I wanted it. The only down recommendation is to replace the easily stripped screws to a more dependable one.

Great feel

Feels durable, sharp, and just how I'd like a knife to feel in my hand. I feel like this is a blade i can rely on. The price was scary at first but once I got a hold of it, no regrets.

Great Knife.... Except...

From AFMedic542

from Lawton, OK

I love this knife in every way except there is one feature that I'm fighting the urge to grind off, The Window Punch! Everything on this knife was really designed well for the Public Safety Officer in mind. However, the Window Punch is particulary effective at snagging and shredding the insides of pockets as it is clipped to the opening. So far it has ripped holes in every pair of 5.11 EMS and Tactical Pants I own. If you're not proficient with a needle and tread, and like your pockets to be hole free - Do NOT buy this knife. I'm hoping that they will redesign this knife in the future to remove this problem cause it IS the best knife I've carried.

Use it every day, never leaves my side!
