British Tactical: 5 inch ‘Mad Jack’ Knife Sheath

4 min read

John Malcolm Thorpe Fleming Churchill AKA Mad Jack


It’s easy to understand why this knife sheath by British Tactical is named after Mad Jack.

If you don’t know Fighting Jack Churchill or Mad Jack, look him up. It will be a good read.


I received this knife sheath from British Tactical to use with my SOG SEAL PUP knife. Since receiving the sheath, I’ve switched knives. Lately I have the excellent Casström Lars Fält knife on my belt to use it as a bush-craft knife when out on the field.

Luckily for me (and because I did the research) the Casström knife fits perfectly in the sheath.

Now let’s talk about the sheath itself.

What is it made of?

The pouch itself is made with Cordura and has some Laser cut 500D Laminate on the front and back.


Looking at the cordura sheath, you can see it’s built like a tank! with an extra edge for added durability. Just look at that stitching!


The laser cut laminate MOLLE grid on the front and back correspond to each other. Because of this you can “sandwich” the sheath between your belt and another pouch with ease! On the front, behind where your knife handle would be they attached a vertical piece of laser cut laminate with loop Velcro on the back. This it to attach the Velcro retention, but we’ll talk about that later.



I currently use the front laminate to attach my Hultafors fire steel.

How can you attach the sheath to your gear?

On the back, there is a Molle attachment system that covers 1 MOLLE width and 5 MOLLE height (9 total coverage). So it can be securely attached when using a wide belt or backpack without it taking up a lot of space in width. I have it attached to my SUMO GEAR belt and it’s very secure. At the end of the strap, British Tactical has attached a small strip of plastic that aids in the routing of it.


How is your knife secured?

There are three ways of securing your knife:

  1. Velcro strap
  2. Elastic band and tab
  3. Combination of the Velcro strap and the elastic band

I use the combination of the Velcro strap and the elastic band because the Casström knife has a pretty slippery handle, resulting in the elastic band slipping off. But to each it’s own.


Is the cordura enough to protect you and the knife?

Of course not! Because everyone knows that a good knife is a sharp knife! Sharp knives can cut through cordura, so British Tactical has made an HDPE card insert that covers the complete blade. The insert just slips into the sheath and I have never had any issues with it. Having the only “hard part” of the sheath on the bottom also helps with the comfort. Sitting in a vehicle with a knife sheath attached to your belt can be troublesome, but the knife can move out of the way while still being secure!


Some specifications from British Tactical:

Pouch Weight:

  •   68 grams (Without Knife)

Pouch Dimensions:

  • Width – 6cm
  • Height – 25.5cm
  • Depth – 1cm (with card)

Blade Dimensions:

  • Length – 5 inches
  • Width – 1 1/4 inches
  • Hand Guard length – 4 1/2 inches

MOLLE Attachment/Coverage:

  • Attaches to 1 wide by 5 high.
  • Covers 1 wide by 5 high.


I like this sheath. It does what it needs to do and is customizable to your needs for securing the pouch and the knife.

It’s available on the British Tactical website in Multicam, black and of course Coyote Brown for £24.60. They also have 6 and 7 inch version, as well as one specially made for the SA80 bayonet.

I’m now thinking of buying a Multicam one for my outdoor belt.

If you’re looking for a good sheath for military or outdoor use, go check this sheath out!
