The initial sharpness was fairly low, any attempt to measure it just recorded
zero as it is clearly lower than 5% of optimal (it would just break light
baisting thread for example when a push cut was attempted). It could only
slice very rigid paper (photocopy) and even then it was rough. However
it could still do any utilty cutting required as noted in the shot at the
right :
cardboard
pallet wrapping
foam
plastic bottles
pop bottles
food can (chopped not sliced)
The lower sharpness did however mean that more force had to be used and
a longer draw. For example the freshly sharpened
MT-151 cuts the pallet wrapping with no travel on the
blade whereas the mini-hatchet requires two full slices at multiple times as
much force required.
For a bit of further quantification, an attempt was made
to cut 3/8" hemp, but 75 lbs of force could only just score the
rope on a full draw.
In short, from a utility perspective the hatchet
could benefit from a decent sharpening.
However on wood work the mini-hatchet was capable of generating
fine curls but it could benefit from a sharper edge as the
wood is being tore a little which means more force has to be
used. But again a large difference could be seen comparing it
to a sharper tool with a finer edge. For reference the shot on the
right shows the pile from the mini-hatchet after 200 slices
and one from Buck Hoodlum after
just 100 slices.
It is immediately obvious that the performance
difference is many to one in regards to volume even with the
Hoodlum only taking half as many cuts.
The thinner and more acute edge on the Hoodlum and sharper edge
allow it to bite into the wood much deeper and just strip off long
shavings.
The squarish nature of the haft on the mini-hatchet does also
make it get a little uncomfortable after such work.
Before much more work was done the blade was reground :
removing the heavy secondary bevel
flattening much of the primary grind to remove the hollow
slightly raising the primary grind
The resulting bevel was approximately 10-11 degrees per side, the same
angle as on a typical Mora. A slightly heavier secondary
edge was added back,
aproximately 12-14 degrees per side and about 0.015" thick.
This was added to increase the strength of the edge to allow it to
resist lateral loads when chopping.
With the reground and resharpened edge the hatchet could :
As noted in the picture in the right, another one hundred slices into the
same wood showed a vastly increased ability to slice wood in both ease of
making fine shavings and also in hogging off large amounts of material.
With the work smoothing out the sharp contours of the haft there
was also no issue with dicomfort in extended use.
Compared to the Fiskar's Hatchet the
North 49 mini-matchet was significantly out powered for heavy work.
Even a brief chopping comparison with full swings
showed the following :
a 2x4 sized piece of seasoned wood is about the limit that the
North 49 will work on efficiently
the Fiskar's had much more power on the swing
the North 49 therfore was significantly behind on penetration
However when light swings were used the thicker bit on the Fiskar's would
fall behind as it needs the power to drive that thick wedge into wood. In
comparison the North 49 can work very effectively even with very light
chops.
Food
With a freshly sharpened edge the mini-hatchet had no problems
cutting meats and fuctioned similar to a heavy ulu.
the curvature works well in slicing meat
the light chopping ability and heavier edge compared to a
chef's knife means there is no issue in working through joints
of rabbits, chickens and other small animals
with a bit less than ideal technique.
In the video on the right the mini-hatchet
looks to be more awkward
than the custom Takach forge
however this is just due to experience as much more of this
work is done with long blades than ulu's and cleavers. This illustrates
how experience can easily dominate performance in different blades.
Of course on thicker vegetables more force has to be used than a decent
chef's knife. A few comparative cuts:
While it would never replace a decent kitchen knife, aside from peeling,
for which is it fairly awkward as the edge is so far in front of the handle,
it works well for just quick and rough cutting such as needed to make
a basic stew. It is a lot nicer to use in the kitchen than for example
the Wildlife Hatchet simply because the
bit on the North 49 mini-hatchet is only 3/16" thick so it can still make
functional cuts on thicker vegetables.
Field
Using the North-49 mini-hatchet for some light felling (saplings) and
limbing alongside the Buck Hoodlum :
the small hatchet works very well in tight situations where
there is not enough room to swing larger blades
the Hoodlum has a pronounced advantage in sweeping off
more of the small branches at a time when there is full room
the hatchet needs a rear grip both for comfort, security and power
In short, it works well on saplings and small limbs, especially in tight
situations, but is many to one behind a decent long blade on limbing
such as the custom from Takach forge.
Grip
The rubber handle is decently shaped and comfortable, though the end
is a little too thick compared to the forward section. The biggest problem
was that the haft was left fully squared and thus the edges on this were
broken to make them comfortable for finer work. The more rounded they are
shaped then the more work that can be done without discomfort. The only real
loss of functionality with this is that there is a reduction in scraping and
some hammering (to break) with the haft but it is a personal choice with this
over the comfort for forward grips in cutting.
On an issue related to the grip, as the heft of this little hatchet is so
light, in order to work with it on wood of any size it has to be held in a
rear grip with two fingers. As it is so light and the rubber handle has a very
solid level of traction there is no problem with it slipping out of the hand
however as there is some movement, after hundreds of chops this will start to
produce some hot spotting on the side of the thumb. However from a practical
perspective this really isn't a significant downside as it isn't like this
much cutting would ever be done with this hatchet outside of stock comparisons
anyway.
Edge Retention
A brief examination of the edge retention of the mini-axe on pine
revealed the following after 1000 slices :
there is no obvious effect after 100 slices
it takes 500 slices to even notice any visual effect on the edge
after 1000 slices it still scrape shaves and retains a measure
of ability to slice newsprint
without careful measurement it would be hard to detect the loss of
sharpness at all
It is also easily restored to optimal with a minute on a fine stone
(4000 grit) to cut off the burr and weakened metal and then restore the
edge.
Another quick check of the mini-hatchet is shown on the right using it in the
kitchen after the chopping noted in the above (400 chops in total on various
seasoned lumbers). A few observations :
no visual impaction, rolling or chipping was seen from the wood
work
no slipping was noticed on the bread
almost a perfect push cut could be made on the slab bacon
Again considering the price of this blade, the ability to chop up effectively
20 2x4 sized pieces of wood and still retain this level of sharpness isn't bad
performance. Of course again it is a bit awkward to use for such work but for
a flat hatchet (heavy cleaver) it isn't bad when properly sharpened.
Comparing the North 49 to the Buck Hoodlum to
check the edge retention chopping, both were used for over 500 chops into
various scrap lumbers :
osb
plywood
spruce board
As the wood was outside there was some grit, some of it frozen onto the
surface as the weather lately had included freezing rain. A lot of it was also
breaking during the cutting as most of the chopping was done in sub-zero
temperatures between -5 and 0 C.
The chopping was done with full force, however as both of these are very light
both were used with partial or rear grips and basically swung from the elbow
as there was no use in trying to drive from the shoulder. As necessary they
were also twisted to clear the wood as again since both of them are a bit
light they didn't always have the ability to clear fully just through chopping
alone. During the chopping there was no noticeable loss of sharpness however
wood chopping is only lightly dependent on sharpness and an edge has to be
extremely dull to really effect performance. Note as both of these are similar
in :
heft
length
edge angle and thickness
The comparison can be used to infer about the properties of the steels at
least in a very general level.
In regards to pure performance based on penetration (inferred from chop count)
as noted in the histogram on the right, through over 500 chops (more than 50
pieces of wood cut with each) the performance is basically identical as the
results all cluster around 1:1 . Of course there is some spread, there is a
lot of variation in wood from one piece to the next, even in the same length
of stick but even after just a few cuts it is obvious the penetration is very
similar in both blades but that would be expected as again :
heft
length
edge angle and thickness
are very similar for both.
After the more than 500 chops both were checked for sharpness on newsprint
and used in the kitchen on :
bread
slab bacon
over ripened tomato
Both cut the bacon with no noticeable loss of sharpness, slight tearing of the
bread could be noticed and both slipped a little on the tomato on a slice. On
the newsprint, with a slow slice with little draw, then some catches could be
noted. In short, after the 500+ chops though some sharpness could be observed
to be lost, both were still very functional and more importantly, or at least
as important, the performance of the North 49 is in agreement with the
previous edge retention chopping comparison note in the above.
Sharpening
A little surprising, this little axe sharpened very well :
high grindability
minimal burr formation
After the edge
was reground as noted above, it was honed on a 200 grit silicon carbide
waterstone, then refined with a 1000, 4000 and then 8000 grit waterstone.
It easily shaved and would push cut newsprint on a 45. However as shown
in the picture on the right,
(50X magnification),
the grits were skipped past a little too
quickly as some of the very coarse scratches from the initial very coarse
hone are still present. To maximize durability and edge retention when
chopping these should be removed (however they will increase cutting ability
and edge retention on a draw, especially through abrasive media).
In closer comparison with several repeated sharpenings, the edge does not
show the true benefit of the 8000 grit waterstone and retains a bit of
coarseness to the finish. This is likely due to the less than idea
heat treatment of the steel which has left the aus-grain of the steel
a little too coarse. However again considering the price point and
the performance noted which can be achieved in regards to sharpness,
cutting ability and edge retention, it is hard to argue it isn't impressive
for its price.
Overview
Overview :
very heavy initial edge and hollow grind
requires a regrind to optimize cutting and durability
decently comfortable and durable grip
sheath is functional
very lightweight axe, suitable for a kindling axe
nice carving ability, limited splitting ability
In short after some very necessary regrinding the North 49 mini-axe is very
nice for a utility/food axe.
