Well, I've done the re-hanging thing, so this one is about choosing. These few notes are intended to help the newcomer to picking out an axe that is suitable fortheir purposes. They aren’t a complete guide to axemanship or intended to be such, just moreof a “bluffers guide” to selecting an axe suitable for your purpose. Parts of the Axe Before we get into anything involved, its probably helpful to define the terms we will use.
A: Heel of Head Right there are several things we should consider in selecting an axe. The most important of all of these though is purpose. Purpose Axes serve three major purposes, cutting, splitting and shaping. Profile Lets understand first how to differentiate between a cutting axe and a splitting axe. In effect,this is determined by the “profile” of the axe. Lets look at a cutting profile first.
See how thin this is? This is to penetrate “across grain”. The thinness means that it presentsthe maximum force on a low surface area (think razor blade) and “severs” what it cuts across.Its great for cutting as a result. It is less good at splitting as, when cutting into a log, it willtend to slide in between the fibres of the wood with minimal interruption, This is like shaving afeather stick and is unlikely to cause a split to “run” through the log. So what does a splitting profile look like? See how wide the angle is? Imagine this slammed end on into a log! It has a wedge like actionand forces the log apart. It expends all its energy in this way causing a deep split that forcesthe grain apart. It is optimised for this task though. If used to cut “across grain”, it will notpenetrate deeply as it will be trying to sever far more fibres that a narrower profile “cutting”bit has to. It will therefore stop in a more shallow cut.
Bit Shape So we understand that a wider profile helps to split, a narrower to cut. So what about a shaping axe? Well, this is more in the shape of the bit than the profile. Lets look at the bit shape of an axe that will cut or split.
See how pronounced the curve of the bit is? This means that only a small part makes contactwith the wood at a time and so, like a knife point, it aids wood penetration (with or across the grain) A shaping axe bit looks like this.
See how flat it is? This is to give an even cut rather than a deep cut. There are varieties on this theme. The broad axe has a completely flat bit and ramp on one (or rarely both) sides. This allows the axe to be laid on a flat section and chop out a very flat section of wood. According to the side that is flattened you get a right or left handed broad axe. For general woods purposes, a rounded bit is more versatile. Having considered the head shape, perhaps we should think about type of head. Here we havetwo main considerations – single or double bit. Single bit The single bit axe is more common and offers some advantages. Its design is optimised to put all the torque (rotational power caused by swinging around a pivot point- the shoulder) behind the one bit it possesses. The poll is hardened in some axes (notably Wetterlings) and cantherefore be used for hammering. A single bit axe can also be battoned and, when combinedwith hard wood wedges, even a small hatchet can split an entire hardwood tree when in the hands of a skilled user.
Double bit A double bit axe offer different advantages. It is generally symmetrical around a centre line.This offer a balance not found in a single bit axe. Whilst it can’t be battoned. The two bladesare often ground differently to offer splitting and cutting profiled offering a large degree ofversatility in a single tool. When applied to a hatchet sized axe this is known as a Nessmukgrind after the famous author of that name.
Haft Length Axes come in a bewildering variety of lengths. Clearly each length can be combined with any of the head types above, but, ignoring the shaping part, each length is generally used for a specific purpose. A few choices are shown below. Pocket (12" 1 lb weight) Pocket axes are often underrated. A small pocket axe (12” long) will split a short 6” log onehanded and can be pressed to much harder use when battoned. The model illustrated is the“Marbles pocket safety axe”. It has the advantage of an integrated metal cover that cover thebit and also folds away into the handle. It easily fits into a coat pocket and is perfect for alight wander through the woods when you don’t want to be too encumbered.
If you doubt what can be achieved with a small hatchet, checkout this picture of a Vaughan mini hatchet punching above its weight!
Hatchet (18" 1 1/2 lb) Possibly the most versatile and best loved all round bushcraft axe. The best length for one handed use. The model illustrated is the Wetterlings Large Hunters axe, but I would alsoconsider a Gransfors Bruks Small Forest Axe or Roselli Large Allround in this category (the Roselli has a more splitting oriented profile)
Limbing (24" 2lb) A limbing axe evolved for a specific purpose – standing on one side of a tree trunk and cuttingthe limbs for the other. It is usually a cutting profiled axe. The unusual (not quite one handed,not quite two) length makes for a very versatile compromise axe for general use – lightenough for one handed use – long enough for two handed.
Felling / working (36" 3 - 4 lb) This of course is the “full size axe”. My personal favourite in this area is a double bit workingaxe. Beautifully balanced, with a broader profiled bit for working near the ground on limbs andwhere the bit might be damaged and a narrower one for power of cut.
That said, there is certainly a place for the every day felling axe. This one is a simple, grphandled 3lb felling axe that I’m happy to lend, use and do tough tasks with.
Maul / splitting ( up to 8lb 40") This of course is the heavy artillery of the axe world! A huge pointed sledge hammer designed to split wood rounds and never used for cutting. A specialised tool that is devastatingly effective when used with wedges and wood grenades (we can cover that separately if anyone is interested)
Haft materials Wood. GRP Metal. Selecting an Axe Size is important! There is much talked about axe selection that is nonsense. One piece of advice I do like for anall round camping axe is to match the axe to your arm. Grasp the head of the axe, bit forwardand try to tuck the axe into your armpit. The toe of the haft should sit comfortably inside yourarmpit. This particular technique in an adult male will usually result in a limbing axe selection– don’t be worried to select something smaller if that is your taste and need.
Head alignment The alignment of the head with the haft will do more than anything to improve cuttingefficiency. This varies even with the same model in the best make. Ask to see the whole stockbefore you buy. Hold the head in your hand and sight down the bit. It should perfectly align along the haft and point to the toe of the haft…like this.
Balance Rest the axe across your hand with the shoulder to the neck hanging just off your finger and thumb. The axe should balance perfectly level from the head to the haft toe being level. Neither the poll nor the bit should touch your hand. An axe with this sort of balance is a joy to use.
Haft grain A could quality haft should have the grain running straight from the haft toe to the neck andthe haft shoulder to the haft heel. A small “wander” is okay, trees are rarely straight but a diagonal grain should be avoided as the haft is likely to split.
I hope this is useful – far be it from me to tell anyone what axe to buy – this write up wasmore intended to help illustrate how to make a choice for those that haven’t spent quite as much time playing with toys as I have. |
