CIVIVI Bullmastiff Liner Lock Knife Black G-10 (3.8" Stonewash) C2006C

This Bullmastiff has a black G-10 handle.

The CIVIVI Bullmastiff is named for the dog breed, a burly cross between an English Bulldog and a Mastiff. Originally bred to defend estates from intruders, the Bullmastiff is a large, solid, disciplined dog. The CIVIVI Bullmastiff, just like it's namesake, is tough and dependable. It's made with a thick 9Cr18MoV blade and a G-10 handle. The aggressive cleaver-style blade is weighted toward the tip, ensuring reliable opening with the flipper.


  • Stout cleaver style blade makes a statement.
  • Reliable flipper action tuned to perfection.
  • Reversible deep-carry pocket clip.

Customer Reviews

I love this knife
Eric G. on Apr 19, 2022

I don't usually like Chinese knives, but I wanted a cleaver and I happened to get a bladehq sale email about this knife so I took a chance. This is my first civivi and my first intentionally purchased made in china knife.(NRA and Cabela's both sent me made in china crap as free gift) I love this knife! The size is perfect, the blade steel seems good, it's held an edge so far and came as sharp as I could want right out of the box. The stone washed finish is perfect. It came with a zipper pouch which was a nice touch for this price point. The weight is great, blade geometry is perfect and the fuller let's you do the spydie flick to open if you want. Lock is good with no lock stick and it locks up tight. Pivot is perfect and the detent snaps the blade in and holds it perfectly. Unlike other flippers on bearings that I have this one stays closed when clipped in my wasteband. If I had to find something to gripe about well the g10 handle feels kind of cheap. I don't really love the texture. And the length of handle could be slightly longer. Otherwise this thing is Amazing!!! Highly recommended! Super value for the money!

Heavy and Big Boi

Love this -- what a great wonderful shape; such a heavy profile.

The Big Dog on the Porch
STEVEN G. on Dec 17, 2020

Aptly named, the Bullmastiff is big, tough, and has one helluva bite! The cleaver design is awesome. It fits right in with my other favorite blade shapes: the Wharncliffe and the Sheepsfoot. Despite its pocket profile, I hardly notice I'm wearing it. Even the weight is impressive for such a large knife. Great flipper action even with such a large piece of steel swinging around. I've even been able to reverse flick using the fuller for leverage. The G10 scales have just the right amount of texture. Fun to hold. The liner lock is very comfortable and easy to access and has a subtle texture that makes releasing the lock nearly effortless and pain-free. This is one of the smoothest knives to hold. There aren't any sharp edges (aside from the blade, of course) anywhere on the knife. Even the finger choil feels great. I hope Civivi decides to offer this knife in some upgraded steels, maybe even some copper or brass scales. Anyway, wishful thinking. Enjoy the slice!

More impressive than I thought it would be...
Joseph M. on Oct 10, 2020

...that says a lot because I was impressed before I actually had it in my hand. Sturdy massive blade with a super smooth flip open action. This thing is badass. I am using it as a camping cleaver and for my outdoor kitchen. Its already been put to use on root vegetables and fresh meat

Bullmastiff by Civivi
LONNIE S. on Oct 10, 2020

Really impressed with this knife! Sharp out of the box and carries like a much smaller knife. I will check out more products from Civivi! Customer service from Bladehq is really great also! Thanks!

Great Hunting Knife
Jerry B. on Sep 4, 2020

Takes the wings off a dove without effort, can be used to shave with, and I'm sure it probably will cut your box open. The big wooden box that they shipped your new diesel engine in. Great grip, opens smoothly, makes other people jealous.

Big dog
christopher d. on Sep 1, 2020

Love it was a little concerning about the size of the blade and locking but smooth and very tough for the style of the knife and the shape of the blade can we say bullmastiff!

It's all good
Gary N. on Aug 10, 2020

One of the best pocket knives I own. Smooth action, grippy handle,nice point and most of all very usable ! I don't use pocket clips just toss it in my pocket So dont know about that. Happy with price Happy with shipping / Good all around. Relicblue

Steve S. on Aug 10, 2020

It's smooth. It's sexy. It's big. It's called the Bull Mastiff. What more do I need to say? Just buy this thing.

Big Fun!
Steven L. on Aug 10, 2020
