CRKT are full of interesting and innovative ideas, and with the Homefront and Homefront Tactical bring us ‘Field Strip’ Technology, or in other words tool-less disassembly. The design comes from world renowned Ken Onion and has been a work in progress for many years. Now thanks to this technology you can clean out a build up of grit and dirt wherever you are without any tools. Take your Homefront folder anywhere knowing you don’t need anything else with you to carry out a full strip and clean.<\/p>\n

The Blade and Handle Geometry:<\/h3>\n

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.
\n\"\"
\n\"\"<\/p>\n

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).
\n\"\"<\/p>\n

These measurements have been tabulated and are presented along with a few reference blades (8″ Chef’s Knife, 5.5″ Santoku and the popular F\u00e4llkniven F1).<\/p>\n

Key aspects such as the primary bevel angle, grind type, blade depth, blade thickness, length, weight are detailed, along with balance information.
\n\"\"
\n\"\"<\/p>\n

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.
\n\"\"
\n\"\"<\/p>\n

In the case of full convex grinds the approximate centre of the grind is used for the primary bevel angle estimate.<\/p>\n

\"\"<\/p>\n

The Homefront blade is made from AUS 8 steel and the Homefront Tactical from 1.4116 steel (also known as 420MoV or X50CrMoV15).<\/p>\n

Explained by the Maker:<\/h3>\n

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.<\/i><\/p>\n

Unfortunately I can\u2019t always get time with the designer so will use this section to include relevant information about the knife and its designer.<\/i><\/p>\n

A little description from CRKT’s of the Homefront:<\/p>\n

“It might look like your grandpa\u2019s classic WWII knife, but it\u2019s got an impressive secret. The new Homefront™ knife is the first in our fleet to feature \u201cField Strip\u201d technology. This in-field, no-tool take apart capability lets you purge your most reliable companion of a hard day\u2019s grime right where you are, without ever returning to your workbench.<\/p>\n

The breakthrough \u201cField Strip\u201d innovation comes from the shop of world-renowned knife craftsman Ken Onion and has been over ten years in the making. To disassemble the Homefront™ when the knife is in the closed position, push the front release lever away from the blade, then spin the turn release wheel on the rear of the handle away from the pivot shaft. Once you feel the handle release, pull it up and away from the blade. Reassembly is as easy as reversing the procedure, al-lowing for practical, quick maintenance where you stand.<\/p>\n

From his shop in Kaneohe, HI, Ken Onion designed the tactically inspired, everyday carry Homefront™ knife to stay true to its vintage roots. The bayonet lug-style flipper sets off the smooth open action of the 3.5\u201d modified drop point blade, while tank jimping on the backstrap sits snugly against your palm.<\/p>\n

It stands up to the looks of a WWI heirloom, and it sure as hell stands up to any job it encounters. The handles are made from 6061 aircraft-grade aluminium and house an impressively beefy AUS 8 stainless steel blade.”<\/p>\n

A few more details of the Homefront:<\/h3>\n

This review covers the Homefront (green handle) and Homefront Tactical (black handle), but we are going to look at the original Homefront first. There are no boxes as these knives came straight from the CRKT IWA 2017 display stand at the end of the show. They have been handled and used.
\n\"\"<\/p>\n

The pivot has what appears to be the standard US aircraft star insignia (as used from 1942). The lever next to this is where the magic is hidden.
\n\"\"<\/p>\n

Apparently styled after a bayonet lug, the flipper tab has a hole in it. (Do not try to attach a lanyard here!)
\n\"\"<\/p>\n

Both handles have a subtle grip pattern. This appears to have been laser etched into the surface before anodising.
\n\"\"<\/p>\n

The other bit of magic, comes from the thumb-wheel screw that holds the butt of the knife together.
\n\"\"<\/p>\n

A steel pocket clip also gives you a hole for attaching a lanyard should you wish to.
\n\"\"<\/p>\n

Though not strictly a ‘liner-lock’, tucked neatly into the inner side of the Homefront’s aluminium handle is a sprung steel locking lever.
\n\"\"<\/p>\n

Blade centring is good, with the tip appearing slightly off due to the edge grind.
\n\"\"<\/p>\n

A Torx screw holds the jimped handle spacer in place on one side.
\n\"\"<\/p>\n

On the opposite side to the star insignia, the pivot has an adjustment screw that sets the height of the pivot bolt.
\n\"\"<\/p>\n

Right! Let’s take this knife apart. First loosen the thumb-wheel screw by pushing it away from the pivot. Keep going until the thread ‘clicks’ to indicate it is fully undone.
\n\"\"<\/p>\n

Flip the knife round and push the locking lever towards the flipper tab (with the knife folded).
\n\"\"<\/p>\n

Now, as you lift your thumb, the handles spring apart at the pivot.
\n\"\"<\/p>\n

As we had already loosened the thumb-wheel, the handle can now be lifted away, fully exposing the folded blade.
\n\"\"<\/p>\n

A closer look at the thumb-wheel while we can. Note the circlip; the wheel fits over the threaded bolt, and there is a little bit of play, with the wheel having some movement even when the connector is fully tightened.
\n\"\"<\/p>\n

And this is the magic pivot that lets it all happen. Note the hex-shaped head. The homefront also uses a concealed stop pin which limits the open and closed positions of the blade.
\n\"\"<\/p>\n

Look into the hole of the handle we removed first, and you can see the hex shaped hole that locks onto the top of the special pivot bolt.
\n\"\"<\/p>\n

If you forget how you took it apart, or somehow it just ‘came apart in your hands’, inside the handle is a set of instructions for putting it back together again.
\n\"\"<\/p>\n

When stripped you have the three main components, the master handle (with pivot, stop pin, lock bar and thumb wheel screw), the blade, and the second handle.
\n\"\"<\/p>\n

While it is fully stripped this is a closer look at the special pivot, stop pin and the detent ball on the end of the lock bar.
\n\"\"<\/p>\n

So, not a ‘liner’ , this lock bar is inset into the aluminium handle, but functions exactly as a liner lock.
\n\"\"<\/p>\n

The blade tang has the pivot hole and a semi-circular stop pin slot. The markings in the hole suggest this is a stamping and is not water jet cut.
\n\"\"<\/p>\n

A really good looking blade with swell near the tip and a fuller, giving it a classic look.
\n\"\"<\/p>\n

Ken Onion is credited on the blade. On this side of the blade you can see the detent hole.
\n\"\"<\/p>\n

A close-up of the blade tip, showing the contrast in surface finish and the edge bevel grind.
\n\"\"<\/p>\n

With one handle removed you get a cut-away view of the workings of this knife.
\n\"\"<\/p>\n

Lock engagement is good with the entire lock bar touching the blade tang with a firm snap-open.
\n\"\"<\/p>\n

And in no time at all it is all back together.
\n\"\"<\/p>\n

The Homefront achieves a real vintage look, despite not looking like any historical knife I’ve found.
\n\"\"<\/p>\n

A few more details of the Homefront Tactical:<\/h3>\n

Next we have one of the second wave of Homefront models where instead of the aluminium handles, these have Glass Reinforced Nylon handles and a different blade steel. This is the Homefront Tactical, with a part-serrated Tanto blade
\n\"\"<\/p>\n

The design and shape of the handle is the same as the original Homefront, including the pivot star insignia.
\n\"\"<\/p>\n

In terms of the function and design the GRP handled version is basically the same. Here we have the thumb wheel.
\n\"\"<\/p>\n

And the same steel clip.
\n\"\"<\/p>\n

That bayonet lug flipper. However note that this time the blade is black. It has an EDP finish (electronically deposited paint, which is baked on).
\n\"\"<\/p>\n

A hint of bare steel with the lock bar. We will see that this time it is actually a liner.
\n\"\"<\/p>\n

Although the same grip pattern is used, in this version the width of each line is wider than on the original Homefront. Of course, in this case it is moulded into the surface instead of being laser etched.
\n\"\"<\/p>\n

Going straight for a field strip, exactly as with the Homefront; here the handle is off.
\n\"\"<\/p>\n

The internal curve of the handle spacer is a match to the Homefront’s blade, but here we have a tanto. Clearance is still good. The spacer is also now GRP instead of metal.
\n\"\"<\/p>\n

As before, the pivot has a hex shaped head.
\n\"\"<\/p>\n

Now we see one of the major differences. With the handle being plastic, it cannot have the lock bar screwed to it. Instead there is a full metal liner moulded into the inside of the handle.
\n\"\"<\/p>\n

This full metal liner also has the stop pin fixed to it and supports the pivot. The dirt around the detent ball on the lock bar is worn off paint from the blade.
\n\"\"<\/p>\n

A Teflon bushing acts as the pivot washer. You can see the outline of a metal liner inside the moulded handle. Two screws hold the pivot locking mechanism together.
\n\"\"<\/p>\n

Apart from the cutting edge, the entire blade is EDP coated.
\n\"\"<\/p>\n

EDP is just paint, so where the detent ball rubs on the blade tang, the paint has been scratched off.
\n\"\"<\/p>\n

Looking at the finish on the edge bevel grind.
\n\"\"<\/p>\n

There are part serrations near the handle which are a chisel grind (single bevel) and have two sizes of scallop.
\n\"\"<\/p>\n

The all black Homefront Tactical.
\n\"\"<\/p>\n

And there is more when you put these two together…
\n\"\"<\/p>\n

What are they like to use?<\/h3>\n

Headlined as a ‘field strip’ technology, it could also be an ‘easy disassembly’ feature. You can take the Homefront apart anywhere, but you can also pop it apart any time for a quick service, not only when it needs a major overhaul. By making the deep-clean a super easy process, you are much more likely to keep these knives in top condition all the time.<\/p>\n

The styling of these knives is mentioned prominently by CRKT. The Homefront is described as a remake of grandpa’s WWII, and the Tactical as a classic WWI knife and though there is a vintage look; firstly I suspect the WWI reference is a mistake as the US Airforce aircraft marking Star Insignia was a WWII design, and secondly I would disagree that it is like any WWII folder, certainly none I’ve ever seen.<\/p>\n

Let me make it very clear that I really like the design and styling, which definitely has a vintage look, and incorporates design features that do give a modern interpretation of a WWII knife. My disagreement is with the statement that it looks like grandpa’s knife, show me a knife from WWII that looks like this and I’ll happily eat my words.<\/p>\n

This is really not a negative as, in particular, I like the choice of colour for the handle of the Homefront along with the finish of the blade steel and the inclusion of a fuller. Overall a really stylish design that stands out from the crowd.<\/p>\n

Moving on to how it is in the hand, that most crucial aspect, and this is a good sized folder with plenty of handle to give a stable grip. The handle has an area of grip positioned perfectly for the thumb to sit on when using a saber style grip. It is a relatively slim aluminium slab handle, yet its shaping allows it to fit into the hand very comfortably. Not so well that I’d want to do a lot of heavy cutting with it, but well enough to find it regularly in my pocket.
\n\"\"<\/p>\n

The Homefront Tactical has the same ergonomics, as the handle shape is exactly the same, but the nylon GRP material gives it a different feel, warmer, slightly lighter and a slightly different balance. It does not feel diminished compared to the original Homefront, just a different option. It may only be around 13g lighter, but does feel easier to carry.
\n\"\"<\/p>\n

Talking of options, should you have more than one of the Homefront models you can mix things up a bit and try a different blade or handle. Have a look at this short video to see this and the ‘field strip’ in action.<\/p>\n
