Greatest Tool #10: The Knife

Greatest Tool #10: The Knife
Knife

    If you have been reading my count down, I’m sure it is no surprise to any of you that my number one greatest tool of all time is the knife.

    There are hundreds of different kinds of knives designed for the kitchen alone.

    To choose a knife that is of good quality and best fits your needs, you need a basic knowledge of the various parts and construction of a knife.

    I’ve looked around quite a bit to find the best descriptions at places like the knife depot, buck, and case.

    Let’s start with a few of the blades.

    1. Carbon Steel – Carbon Steel has been used in the making of blades for many years. Carbon steel blades are tough and take a better edge with little effort. Carbon steel blades must be treated with care to avoid discoloration and rusting. Wash and dry thoroughly after use.

    2. Stainless Steel – Unlike carbon steel, stainless steel blades do not discolor or rust, however, neither do they maintain the best edge.

    3. High Carbon Stainless Steel – A combination of the best attributes of carbon steel and stainless steel blades. They have the toughness and ability to hold an edge and do not discolor.

    4. Titanium – Titanium blades are made from a mold of titanium and carbides. When compared to steel, titanium is lighter, more wear resistant, and holds its edge longer. The titanium blade is more flexible than steel but lacks its tensile strength.

    5. Ceramic – Ceramic blades are made of zirconium oxide and aluminum oxide. They are more delicate than steel knives but they hold their edge up to 10 times longer. Once these blades have dulled, they must be sharpened by a professional.

    6. Hollow Ground – Hollow Ground is a process by which a knife blade is manufactured by fusing two separate pieces of metal together. After the pieces are fused, a beveled blade edge is created. Although these blades often have very sharp edges, the blade lacks the balance and longevity of a taper ground blade.

    7. Taper Ground – Taper Ground knife blades are manufactured from a single sheet of metal that has been ground so that it tapers smoothly from the spine to the cutting edge. This type of blade desired on knives that are used frequently.

    Now let’s look at the basic construction of knives.

    1. Tang – It is not what the astronauts drink. The tang is the part of the knife blade that extends into the handle. The length of the tang is thought to be significant in the ability to balance and control a knife. Various manufacturers believe that producing a knife with a tang that extends throughout the full length of the knife is most desirable. Other manufacturers argue that each piece of a knife benefits from using a different metal.

    2. Metal Rivets – Metal rivets are used to secure the tang to the handle of the knife. To prevent irritation to the hand, the rivets should be completely smooth and lie flush with the surface of the handle. In addition, this will help prevent debris and microorganisms from collecting in the spaces between the handle and the rivets.

    3. Bolster – A bolster is a thick piece of metal (collar or shank) that is placed between the handle and the blade. The purpose of a bolster is to provide safety from the blade and add balance to the knife.

    Let’s move on to the handles.

    1. Wood – Wood handles provide an excellent grip, but require more maintenance than a plastic or stainless steel handle. Critics argue that wood handled knives absorb microorganisms.

    2. Wood Handles Infused with Plastic – A combination of the best attributes of wood handles and molded plastic handles. They have an excellent grip but do not require the maintenance all wood handles require. They are also not as porous as wood handled knives, preventing the absorption of microorganisms.

    3. Molded Plastic or Composition – Molded plastic handles are much easier to care for than wooden handles. They will not absorb debris and microorganisms and are easily cleaned. Critics argue that handles made with molded plastics become brittle over time and can become slippery in the hand.

    4. Stainless Steel – Metal handled knives last longer and adds weight to the knife. Critics argue that they become slippery in the hand.

    Above and beyond construction we can look at the styles of knives.

    1. Fixed Blade Knives
    A fixed blade is a knife in which the blade does not fold and extends most of the way into the handle. This type of knife is typically stronger and larger than a folding knife. Activities that require a strong blade, such as hunting or fighting, typically rely on a fixed blade. Some famous fixed blade designs include the Ka-bar and Bowie knives.

    2. Folding Knives
    A folding knife is one that has a pivot between handle and blade, allowing the blade to fold into the handle. Most folding knives are small working blades; pocket knives are usually folding knives.

    Some folding knives have a locking mechanism:

    • The most traditional and commonplace lock is the slip-joint. This isn’t really a lock at all, and is found most commonly on traditional pocket knives. It consists of a back spring that wedges itself into a notch on the tang on the back of the blade.
    • The lock back is the simplest true locking knife. It is found on most traditional locking knives. It is like a slip-joint, but the lock consists of a latch rather than a back spring. To disengage, one presses the latch on the spine of the knife down, releasing the tang.
    • The linerlock is the most common today on knives, especially so-called “tactical” folders. Its main advantage is that it allows one to disengage the lock with one hand. It consists of a liner bent so that when the blade opens, the liner presses against the rear of the tang, preventing it from swinging back. To disengage, you press the liner to the side of the knife from where it is attached to the inside of the scales.
    • The framelock is a variant of the linerlock, however, instead of using the liner, the frame functions as an actual spring. It is usually much more secure than a liner lock.

    Then there are knives grouped by function.

    In general, knives are either working (everyday-use blades), or fighting knives. Some knives, such as the Scottish Dirk and Japanese Tanto function in both roles. Many knives are specific to a particular activity or occupation:

    1. A hunting knife is normally used to dress large game. It is often a normal, mild curve or a curved and clipped blade. Hunting knives are a staple in the extensive world of knives. The term “hunting knife” is used loosely to mean any standard straight blade sheath knife that is at least somewhat geared towards real hunting use. In reality most of these knives are never used to dress an animal or for hunting related uses. There are some types of knives that are made specifically for hunting practices. The use of a “skinning knife” is obvious. They generally have a short, tough, razor sharp blade that is designed to easily separate hide from flesh. Skinning knives will sometime have a dull, barbed hook on the tip of the knife for eviscerating game. This is often referred to as a “gut hook.” There is no perfect “hunting knife”. The ‘right’ knife will be determined by the specific use, kind of game, and hunter’s preference of materials and style. There is certainly no lack of choice for someone who is looking for a knife made for hunting purposes.
    2. A stockman’s knife is a very versatile folding knife with three blades: a clip, a spey and a normal. It is one of the most popular folding knives ever made.
    3. Utility or multi-tool knives may contain several blades, as well as other tools such as pliers
    4. An electrician’s knife is specially insulated to decrease the chance of shock.
    5. A kukri is an Indian fighting and utility knife with a deep forward curve.
    6. A machete is a long wide blade, used to chop through brush. This tool (larger than most knives, smaller than a sword) depends more on weight than a razor edge for its cutting power.
    7. A survival knife is a sturdy knife, sometimes with a hollow handle filled with equipment. In the best hollow-handled knives, both blade and handle are cut from a single piece of steel. The end usually has an O-ring seal to keep water out of the handle. Often a small compass is set in the inside, protected part of the pommel/cap. The pommel may be adapted to pounding or chipping. Recommended equipment for the handle: a compass (usually in the pommel). Monofilament line (for snares, fishing), 12 feet of black nylon thread and two needles, a couple of plastic ties, two barbed and one unbarbed fishhook (unbarbed doubles as a suture needle), butterfly bandages, halizone tablets, waterproof matches.

    I’m just saying its way cool.

    How to Plan Your Life Goals and Actually Achieve Them

    How to Plan Your Life Goals and Actually Achieve Them

    Where do you want to be 5 years from now, 10 years from now, or even this time next year? These places are your goal destinations and although you might know that you don’t want to be standing still in the same place as you are now, it’s not always easy to identify what your real goals are.

    Many people think that setting a goal destination is having a dream that is there in the far distant future but will never be attained. This proves to be a self-fulfilling prophesy because of two things:

    Firstly, that the goal isn’t specifically defined enough in the first place; and secondly, it remains a remote dream waiting for action which is never taken.

    Defining your goal destination is something that you need to take some time to think carefully about. The following steps on how to plan your life goals should get you started on a journey to your destination.

    1. Make a List of Your Goal Destinations

    Goal destinations are the things that are important to you. Another word for them would be ambitions, but ambitions sound like something which outside of your grasp, whereas goal destinations are certainly achievable if you are willing to put in the effort working towards them.

    So what do you really want to do with your life? What are the main things that you would like to accomplish with your life? What is it that you would really regret not doing if you suddenly found you had a limited amount of time left on the earth?

    Each of these things is a goal. Define each goal destination in one sentence.

    If any of these goals is a stepping stone to another one of the goals, take it off this list as it isn’t a goal destination.

    2. Think About the Time Frame to Have the Goal Accomplished

    This is where the 5 year, 10 year, next year plan comes into it.

    Learn the differences between a short term goal and a long term goal. Some goals will have a “shelf life” because of age, health, finance, etc, whereas others will be up to you as to when you would like to achieve them by.

    3. Write Down Your Goals Clearly

    Write each goal destination at the top of a new piece of paper.

    For each goal, write down what is it that you need and don’t have now that will allow you achieve that goal. This could be some kind of education, career change, finance, a new skill, etc. Any “stepping stone” goals you removed will fit into this exercise. If any of these smaller “goals” have sub-goals, go through the same process with these so that you have precise action points to work with.

    4. Write Down What You Need to Do for Each Goal

    Under each item listed, write down the things that you will need to do in order to complete each of the steps required to complete the goal. 

    These items will become a check-list. They are a tangible way of checking how you are progressing towards reaching your goal destinations. A record of your success!

    5. Write Down Your Timeframe With Specific and Realistic Dates

    Using the time frames you created, on each goal destination sheet write down the year in which you will complete the goal by.

    For any goal which has no fixed completion date, think about when you would like to have accomplished it by and use that as your destination date.

    Work within the time frames for each goal destination, make a note of realistic dates by which you will complete each of the small steps.

    6. Schedule Your To-Dos

    Now take an overview of all your goal destinations and make a schedule of what you need to do this week, this month, this year – in order to progress along the road towards your goal destinations.

    Write these action points on a schedule, you have definite dates on which to do things.

    7. Use Your Reticular Activating System to Get Your Goal

    Learn in this Lifehack’s vlog how you can hack your brain with the Reticular Activation System (RAS) and reach your goal more efficiently:

    8. Review Your Progress

    At the end of the year, review what you have done this year, mark things off the check-lists for each goal destination and write up the schedule with the action points you need for the next year.

    Although it may take you several years to, for example, get the promotion you desire because you first need to get the MBA which means getting a job with more money to allow you to finance a part-time degree course, you will ultimately be successful in achieving your goal destination because you have planned out not only what you want, but how to get it, and have been pro-active towards achieving it.
