One of my highlights of IWA 2016 was a visit to the CRKT stand, and on that stand was a knife I could not leave IWA without. Amongst the new Ruger line of knives (produced by CRKT) was the super-sized Go-N-Heavy which stood out not only due to its size, but for the distinctive look which comes from a combination of the design brief for the Ruger line of knives and its pedigree of being a William Harsey design.

The Blade and Handle Geometry:

Most knife specifications have a basic description of the blade geometry, but in this section I will be taking a more detailed look at geometry and balance.

Using a set of gauges and precision measuring equipment including a Vernier protractor, callipers, fixed radius gauges and the unique Arc Master adjustable radius gauge (the one that looks like a crossbow).

These measurements have been tabulated and are presented along with a few reference blades (8″ Chef’s Knife, 5.5″ Santoku and the popular Fällkniven F1).

Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.

The ‘Balance relative to the front of the handle’ tells you if the knife will feel front heavy, or if the weight is in your hand (a positive value means the weight is forward of the front of the handle). The ‘Balance relative to the centre of the handle’ indicates how close to a ‘neutral balance’ the knife has in the hand.

In the case of full convex grinds the approximate centre of the grind is used for the primary bevel angle estimate.

The blade is made from 8Cr13Mov steel, the washers from Teflon and the handles are hard anodised 6061-T6 Aluminium.

Explained by the Maker:

The reasons for certain design choices may not be clear when simply looking at an object, so this section is intended to give an insight into the thinking behind a design by speaking to the designer themselves.

Unfortunately I can’t always get time with the designer so will use this section to include relevant information about the knife and its designer.

While discussing the Ruger knives with CRKT, there were a couple of insights into the processes that led to the final designs of the knives.

The project started with Ruger approaching CRKT and asking them to design a special line of knives for them. The knives had to represent Ruger, so would not simply be any old design, but had to fit in with the feel of Ruger’s products.

As one of the designers CRKT have worked with before, it turns out that Bill Harsey had already been working on a design that was reminiscent of the Picatinny rails on the SR line of rifles. Never quite making it off his workbench, it seemed a perfect fit, so was adopted for the Go-N-Heavy and Go-N-Heavy Compact knives in the Ruger lineup. The Ruger range also includes a total of 23 different models, fixed and folding, plain edges and part-serrated.

A feature used in CRKT knives are the unique Veff Serrations (which we will see in more detail). A different take on the design of serrations where the scallops are angled to give a positive feed into the cut. The effect is similar to a normal wood saw where the teeth cut into the material in one direction, but ride over the surface (clearing the cut) in the other. Veff serrations give real bite to the cut. We will cover these in more detail later.

A few more details:

This review is going to look at both versions of the Go-N-Heavy, the plain edge and part-serrated (Veff serrations). The knife arrives in a Ruger branded box.

Inside the knife is in its belt pouch and wrapped in a plastic bag.

Along with the knife and belt pouch is a CRKT leaflet.

Especially important as this is a large folder, there is a well finished nylon belt pouch.

The belt pouch loops allow for horizontal or vertical carry positions.

That large belt pouch is filled by the Go-N-Heavy.

Let’s take a look round this, starting with the Ruger side of the blade.

Then the CRKT side of the blade. (On this side you can see the stainless steel lock insert/liner.)

Centring is pretty much spot on. Oddly, I’m looking at the actual knife right now and it looks better than this photo.

Loving the details in the handle. Though not a Picatinny rail, it is certainly reminiscent of one.

Enough blade is exposed to allow two handed opening, but there is also an ambidextrous thumb stud fitted to the blade.

One side of the pivot has a torx fitting for adjustment. The pivot bolt appears big and oversized, but this is for stylistic reasons and sits very well with the black anodised handles.

Here we can see the blade stop pin and locking surface (which is fresh and unused straight out of the box).

And out comes that nice big blade with recognisable Harsey style.

Both versions together to show how it looks open and closed.

One side of the blade has the CRKT logo, plus model, engraved into the surface.

Lock engagement straight out of the box looks a little light, but was strong and soon settled in slightly with use.

Stepping back a little this view shows how the stainless liner fits into a recess in one of the aluminium handles.

The holes in the handles do go all the way through. You might also spot that the holes in the stainless steel liner are slightly smaller.

Only one side of the pivot bolt has a torx fitting. The other side is completely plain.

The plunge line is neatly executed.

Torx bolts are used to hold the handles together.

On the thumb ramp there is some fine jimping to give you extra grip.

Taking a very close look into the Go-N-Heavy with the blade open you can see the detent ball on the side of the lock bar which holds the blade in the closed position.

There is a nice flowing semi-swedge on the blade spine.

Now a switch over to the part-serrated version featuring Veff serrations.

Really heavy-duty serrations with only four scallops in the serrated area.

From the other side of the blade you can see the serrations are cut with a single bevel.

The two versions.

What is the Go-N-Heavy like to use?

Before we go onto using it, to start with we have to get the proper ideal of scale, so here the Go-N-Heavy is next to the Fällkniven F1 and a Spyderco UK Pen Knife. Yes, it really dwarfs the Fällkniven in blade and handle.

I take XL size gloves, and this knife makes my hand look small. What the large handle does allow for however are a range for different grip positions all of which remain comfortable.

Ok, I’m not going to argue that it is the most practical knife, but saying that there are plenty of occasions I want to have a large knife with me but can’t really justify a fixed blade. The Go-N-Heavy gives you a knife with presence but which is small enough when folded to pop into a bag or onto your belt and not be too noticeable; until you need it.

There is also just something so satisfying about a big folder, watching that large blade appear and the knife double in size. When at IWA I found it very difficult to put down, and knew exactly which CRKT knife I wanted to test.

Perhaps a little over sized for a box cutter (especially as you might end up going through the entire box and cutting the contents), but it did the job. Clearly this is not what the knife was intended for.

Though the factory plain edge was serviceable enough, I decided to give it a bit of an upgrade and pop a Wicked Edge onto it.

Looks rather nice with its new edge.

Unfortunately no large rope cutting tasks have yet presented themselves, so I’ve had to make do with smaller ropes. On the smaller sizes, the rope tends to stick in one of the serrations rather than the serration sawing through. It makes it more like a series of line cutting hooks. You need to scale up the cutting job to really get the Veff serrations showing their power. They look great, and are very aggressive, but on smaller jobs they can be hard work.
What you really can feel is the effect of the angled serrations; they actively bite deeper into the material as you cut instead of riding over the surface. In the right cutting job it makes for a very aggressive and efficient cut. For smaller jobs you often have to push the cut away from you to stop the teeth biting so deeply.

Serrated or plain edge, its your call and depends on your requirements (I’d love to see a mid-serrated version – see The Mid-Serrated Blade – A new concept from Subwoofer). Either one will give you a really satisfying super-sized folder.
