Why the new Qtrmstr & Heinnie collaboration is bringing back the friction folder

The vast majority of people now think that the primary joint for a UK Friendly “legal” folder is and should be a slip joint. However, you should not forget the friction folder.

We hope that the new Heinnie Haynes and Quartermaster Knives collaboration ‘Barney Mcgrew is going to help make sure that friction folders remain at the forefront of your mind when buying a new knife, whether it’s for UK carry or not.

Now let’s talk a little about the knives themselves.

There are two variations

There are two versions of this knife. The difference is small, but can be quite important. Essentially the only difference is on the scale upon which the pocket clip is mounted you can either have a UK flag laser etched in or not (take a look at the pictures below). For the patriotic sort this is awesome and looks really, really cool. For those who want to keep it simple or have it shipped elsewhere in the world then maybe the non-lasered version will be for you.

Barney McGrew Collaboration - Qtrmstr & Heinnie Haynes


The design is quintessentially Quartermaster, you can definitely see their distinct way of knife making, which is what has made them so popular. However, this design is probably one of their simpler designs. That’s neither good nor bad, just different.

As these knives are obviously friction folders, you get an extended tang. This extended tang is not only extremely well designed but it also has an awesome added feature. You’ll notice there is a hole in the tang, well when the blade is open, this hole aligns with another hole in the scale. Why? Well with this knife you get a locking pin that securely holds the tang in place, making this a locking knife. If you want to use this knife as a UK EDC carry then you’ll have to leave the pin at home. But, if you wanted this knife as a locking blade then it’s possible. In essence you get two different knife types in one package!


The blade, pocket clip and one of the scales have lovely stonewash finish, which gives the knife a little extra dimension. The next thing we want to draw your attention to is the reverse tanto blade. Compared to a normal tanto you get a fair bit more cutting edge, it also still looks awesome! More cutting edge, similar awesome look.

The final design feature we want to bring to your attention is the blade lock. A historical problem with friction folder knives was that they had a habit of opening in your pocket. This is a thing of the past now. This neat little blade lock will prevent the knife from unwanted opening. For all those of you who didn’t like friction folders because of their unpredictable opening, you now need not worry. It’s simple to use and effectively holds the blade. Problem solved.



Now it’s all well and good having a great looking knife with some cool features, but if it doesn’t feel right in the hand or do the job it’s designed for then it’s pretty pointless. Well the shape of the handle and blade is distinctive, yet it feels great. The finger choil is placed perfectly and the slight curvature on the bottom of the scales fits the hand nicely (at least for us it does). The gimping across the top of the blade and onto the scales is good. It is of good length and depth to provide lots of grip. The extended tang has been well designed too, so that it slots effortlessly into the scales and adds a little more gimping.

There is something about this knife which makes it stand out from anything else out there. The design is unique and innovative with some fantastic little features.


Is this the start of a move back to friction folders as a staple part of UK EDC knives? Or will it not dent the dominance of the slip joint? You may think we are biased simply because this is our collaboration, but truly if you look and feel one of these blades in your hand you will be impressed!!

On a final note you may have noticed that this knife is called ‘Barney Mcgrew’, this name will likely be lost on most people stateside, but for those of a certain age over here, it should be quite well recognised. What this name tells us is that right from the outset this is a knife aimed for the UK market. It’s not something designed for somewhere else and shipped over. This is a British knife made in America. If you are liking the sound of this knife but haven’t clicked through to buy one, here is the link 😉

    While a good idea I just don’t think it looks nice, maybe you could post some in hand photos or a video where it’s handled.

    I want to like it but it looks like too much is going on to me with a tanto style blade, angled final position on top of the already busy scales but maybe it’s because of the photos.

    Although this is technically UK legal carry there is no way in hell I would want to get stopped with this in my pocket! It looks quite vicious, especially to the “average” person. It’s a shame because I actually quite like the design. Unfortunately legality is not the only thing that matters.
