Well I have been saving these photo’s up for a special occasion ….and I guess my 1000 post qualifies ….

Here are the knives in the chop off …

Busse Killa Zilla –

We had a fair bit of snow here this winter … “here” is up in our Pennine Mountains and mostly it is Moorland … little cover so we also get some very high winds … as a result some of the trees on my property are often casualties. Here is a good example.

This one has snapped off at the height it clears the shelter of the wall and gully …probably a mixture of frost and the wind. It has fallen awkwardly between surrounding trees and access is not to easy. You need to be careful working amongst this sort of cover as tripping on branches and holding knives can be a bad combination. I always wear sturdy boots when chopping with knives. I placed the knives for the test close to the foot of a tree a bit away from the one needing clearing for safety but even then accidents can happen. I went to pick up the CS Khukri which had fallen over to take a pic and busy looking at this knife I did’nt notice just brushing up against the Zilla… and I mean just brushing it … hardly touched it as it still remained stuck in the soil. Here is a pic of my Yeti Gaiters at the toe …

cut straight through the rubber rand :eek:… so this trip was already a bit more costly than I intended… but I can send them of to be repaired…so no lasting harm done…. and there was obviously nothing wrong with the edge on the Zilla either.
All the knives have very sharp convex edges … some have been re-profiled …. The NMFBM was a CG model which I stripped and finished off the full convex grind and thinned the profile on it to more of an appleseed shape than a pear drop shape … a bit steeper but still tough. I did the same with the Zilla. The edges are at around 40 degrees inclusive right at the edge…but have a better profile from the shoulder to the spine for bitting in deep. Jerry Hossom’s knife had his own edge and it may be a little finer … it is the sharpest knife of the four … an amazing job!

The first task was to drop the tree trunk from where it had snapped. I had to get some steps out for this. I anchored them deep in the soil and went for decorating steps instead of a ladder so I had a wider platform to stand on and could be well away from the tree when it dropped. I started the chop off with the Zilla and it went through the remaining wood holding the trunk in a single chop! This was looking good!

The branch landed well and did’nt get caught up in nearby trees but this meant it was also trapped between these trees and would need to be sectioned where it lay.

P1000924.jpg


There was some room to get at the trunk to section it but it was tight.

P1000925.jpg


I started the job at the crown of the tree to take of the upper splayed branches and leave the straight trunk for sectioning. Cutting just below the “V” split in the trunk I started using the Zilla. The first cuts were to remove the bark at a width the same as the thickness of the branch. As a general rule this gives the optimum space needed for a “V” cut through the branch so that the angle of the knife can still remove chips right to the end of the cut. Starting on a more narrow angle means once you are deep into the wood the knife can bind before it reaches the other side.

The Zilla made quick easy work of the crown. A few strokes and we were nearly through.

The Zilla made simple and quick work of this task.

The next task was breaking up the crown of the tree. It was fairly large and had some thick spreading limbs.

P1000928.jpg


The “power” of the Zilla though is pretty amazing. Going to one of the main cown limbs if virtually went through this in a single chop. This Khukri bites deep!:eek:
Well able to sink right up to the spine…. this is what I wanted to achieve with taking the profile to an appleseed shape …

P1000933-1.jpg


It only took a few further strokes to open this cut out and then trim off the remaining wood at the base to finish lopping off the branch.

P1000934.jpg


Trimming the branches off the limbs with the Zilla was a doddle … single cuts and straight through …

P1000936.jpg


Allowing for the need to clear a number of smaller branches and gain access to break up the crown I decided then to pick up the Hossom XXL Retribution. At only 17 oz’s this knife felt like a feather in comparison to the Zilla and with it’s sharp edge it made rapid and quick work of the branches. Easily able to go through these in a single sweep and to get free hanging smaller twine size branches better than any of the knives.

P1000940.jpg


However when you took the knife to larger sized branches or indeed the trunk the knife started to suffer from it’s sharp thin profile in that it would bite so deep it would then get stuck.

Here is a photo’s where I vividly remember the struggle to pull the knife free…

P1000938.jpg


In the trunk it was understandable as I swung it hard to see how deep it would bite ….
It also though proved to be rather hard to fee from some of the smaller limbs…

P1000937.jpg


With some practise I think you would come to know when to apply a full force swing to go through in a single swipe and how thereafter to go a bit more gently and frequently to prevent the knife from biting so deep it cannot easily be freed.
The hassle with freeing the knife interrupts your rhythm altogether when chopping and so it is better and faster to back off on the power….strange but true….

Here is a pic of the Hossom going through the full depth of the tree trunk…

To keep up a rhytmn I was not using this knife as effectively as it could be used to bite deep...

P1000943.jpg


P1000939.jpg


You will see here much shallower cuts than the knife is capable of …it took about 14-15 each side ( 28-30 in total ) to go through the trunk which is a little more than the others… and it would easily be able to match the other knives on depth …but it did’nt throw out the chips that the other convex blade profiles did …and would simply bite in and get stuck. At 3/16’s thick you were easily able to flex the blade once buried deep trying to free it and therefore needed to be careful to pull it out straight …. but timing wise the extra cuts needed were only increasing the time fractionally and it is so light that the fatigue aspect is probably just the same. Certainly carrying this one onyour belt compared to the others would be an amazing difference …. a feather light knife with amazing performance … but definitely a blade which needs a lot of skill.

I could’nt help wondering as a weapon whether this would either easily lopp of someone’s head or arm ….or alternatively get thoroughly and dangerously stuck…you would definitely need to know when to apply the “gas” on this one or when to back off and just use the edge to “cut”… time and practise are called for here but before that happens I must change the grips …

P1000941.jpg


I have never had “Busse pinky “ before but I did certainly get it on the Hossom …the grips are just too thin for me …I thought this might be the case as soon as I got the knife ….I cannot hold the knife properly and it was sliding inside my palm… so I will speak to Jerry and send them in or maybe get them done over here where I can test out the fit whilst being done…I would like the provenance on the knife to be totally Jerry’s but if I need to attend for “fittings” to get a good fit then I will think about doing them over here ….I get a much more comfortable/secure grip on a larger grip.

After doing the first sectioning of the trunk with the Hossom I changed to the NMFBM … this knife is for me the best of both worlds … it has the big smooth magnum grips which are “ideal” for my hands…it is long enough and light enough to do temporary machete duties …but on chopping chores it works really well …until I experienced the KZ it had the most effective chopping ability of all my knives …

The NMFBM went through the trunk easily…

P1000945.jpg


Able to take good deep “bites” into the wood…

P1000944.jpg


The total number of strokes was about 8-9 either side of the V or 16-18 in total …

P1000946.jpg


Next up was the CS Khukri … this is a great overall weight for a knife with this power …. it to went through the trunk very easily ….

P1000948.jpg


The CS had the difficult section to do as it was the part wedged between two adjacent trees … as a result the angles available for chopping were not ideal and had to be done on both sides which increases the count needed for getting through … but I have tested this knife with the NMFBM in the past and it is a very close run thing on chopping … limbing is more of an advantage for the NMFBM …but on heavy main section work they are very similar …I am sure in ideal circumstances the CS could do the trunk in the same number as the NMFBM did …as it was it took about 30 in total ....

The only difference is one of comfort … the CS grip I have smoothed with a dremel where the checkering was but as can be seen in the photo it still needs the transverse lines at the top and bottom of the grip to be removed…this grip definitely gives “hot spots” and limits your use without gloves…the smooth NMFBM you can use all day.

So which is the best chopper? No surprise there…the KZ went through the trunk in just 9 strokes…admittedly at a slightly thinner section but it is so far ahead of the others that I suspect on the heavier section it would do it around 12 in total…maybe less … it “bites” as deep as an axe…it is infact heavier than my GFB SF Axe but IS also a lot more versatile.

I might do a chop off on the trunk sections between the SFA and the KZ as this would be interesting….I think the KZ might do it in less strokes …it depends on the width of the section …the wider the better for the KZ as it has a longer blade section … however all of these knives did an admirable job …

P1000952.jpg


Here are the five sections created from the chop off and the next task is to split them and dry them off….I might do a follow up on this work as well…

The best overall for me is a hard one to say … it depends on your criteria of weight/belt carry/rucksack carry/and "hours" of expected use ....

The choices then would be dependant on your strength and stamina ...

All I can say is if I saw a guy in the Jungle using the KZ as a machete ....he would be one seriously fit and strong bloke ... :thumbup:

That Hossum is sweet looking! What steel is it made out of? I predict INFI will end with the win.
 
The Hossom is in S30V ....sorry ...should have said that ...

The NMFBM is where my strength and stamina is at and would be my overall choice right now ...

Give me a few more months using the KZ though and a bit of gym work and I might change....

The "ability" of the Zilla on chopping is a lot more than the others ... it needs about 2/3rds of the next best knife ...half that of the lightest ... it weighs though twice as much as the lightest ... as MM might say ... you cannot change the laws of physics ...
but the KZ properly tweaked is certainly "something" to strive towards on a fitness basis .... you could really get in shape using this knife....:thumbup:

It's like "boxing" with sand filled gloves ...:D

I've heard people saying they were unhappy with the test team edition of the Killa Zilla, but never any specifics.

If it chops this well, what are the problems people are having? The weight?
 
Some said weight....some said the level of sharpness as delivered...

I don't see sharpness as being unduly an issue ... a lot of my Busse's have needed this ... many have been re-profiled .... re-profiling a Khukri shape is'nt as easy though as say a NMFBM but it is'nt impossible either ...

I just took a bit of thickness out of the lower section to make the convex shape taper a little more steeply there and did the edge as I always do on an angle of around 40 degrees inclusive but using a convex shape for a beneficial chopping edge...
 
Great review, looks like you got a thorough workout in the process. :thumbup:
 
I have two Zillas and plan on keeping both as choppers when backpacking/camping. One of mine came almost completely sharp and the other one needed a little work but was easy to sharpen. Throw on some inner tube on the grip for comfort and good to go. I never understand people who make the weight such an issue as even as heavy as the Zilla is I don't notice it much in my pack. Thanks for the great pics and the test!
 
Great review, nice to see different blade shapes and makes compared.

You said that the KZ was the best chopper easily I'd be interested in your thoughts as to the best for chopping and stuff like general limbing and splitting?

I use my big knives for these 3 tasks and often find a difference in best overall to best in individual tasks.
 
I have'nt done battoning with all of them ....but if you have the strength/stamina to weild the KZ for long enough on limbing and splitting I am fairly sure it will be the best ... it is a heavy blade though and depending on how long you were needing to do this I could see a NMFBM as a more manageable option ....

Free hanging fronds etc ... the Hossom cuts them best .....
