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.

    10 Simple Strategies to Make Your Life Better Starting Today

    10 Simple Strategies to Make Your Life Better Starting Today

    Habits are an important part of the direction you take your life, and — as I’ll share with you shortly — there are certain daily habits you can adopt right away that are guaranteed to improve your life.

    Think back to when you were just six or seven years old…

    At that age you probably didn’t have many habits. But, as the years went by, you picked up more and more good and bad habits.

    You may not have thought about it before, but habit forming never really stops.

    That’s why it’s never too late to change your habits and transform your life.

    So, if you feel burdened by your bad habits, start kicking them into shape by replacing them with these 10 positive, life-changing strategies:

    1. Go to Bed a Little Earlier and Wake up Earlier 

    Starting tonight, get yourself to bed 30 minutes earlier than usual. And, then make sure you get up tomorrow morning 30 minutes earlier, too. This small change can have a BIG impact on your day. 

    Advertising

    Instead of furiously rushing in the morning to get ready for work, the extra time will give you a golden opportunity to start your day off on the right note. You can drink a smoothie while sitting on your porch, spend 10 minutes exercising and stretching, and still have time to read a few pages of an inspiring book.

    2. Be Grateful for the Good Things in Your Life 

    Setbacks and obstacles are inevitable in life. But, with a positive mindset, you’ll be able to overcome most of these. And, when you do, you’ll boost your self-confidence. 

    This is something you can definitely be grateful for. 

    However, if worst-case scenarios are playing out in your life, then sometimes, to stay strong, you’ll need to keep your mind on the good things that are happening to you. For example, your relationship with your partner might be crumbling, but your career is continuously getting stronger. It’d be easy to feel downtrodden and miserable about your relationship problems —  but, it would be much healthier to keep your mind and gratitude on these things that are going well, such as your career.

    3. Drink Water All Day Every Day 

    I’m sure you’ve heard the advice of drinking at least eight glasses of water a day, but are you following that advice? If not, you’re robbing your body and mind of essential hydration. 

    With the right amount of water intake a day, you’ll be amazed how good you feel — and how good you look!

    4. Take 15 Minutes to Set Goals for the Day, and Then Tackle Them One by One 

    This strategy will put your life into a new stratosphere! And, it’s very simple to do. 

    Advertising

    Simply spend 15 minutes in the morning (either at home or at work) planning what you need and want to achieve during the rest of the day. Once you’ve listed your tasks, the next step is to put them into order of priority. 

    For instance, you have three things to do: catch up with your emails, write a project update, and prepare a briefing for your CEO. It’s best if you put these in order of importance. In this example, your emails can probably wait until you’ve created your CEO brief and updated your project documentation.

    5. Turn Off Your Cell Phone (or Put it on Airplane Mode) When You’re Focusing 

    A 2012 study found that even looking at a cell phone or feeling it vibrate in your pocket can significantly distract focus and reduce your ability to complete complex tasks.[1]

    It’s no surprise really, as our thoughts are subconsciously drawn towards checking our phones when they’re switched on. It’s a bad habit — but one that most of us have. However, when you need 100% focus (like I do when writing my articles), then switching your phone off, or at least putting it into airplane mode, will free your mind and supercharge your focus. Try it and see!

    6. Walk as Much as You Can 

    Have you noticed that most people’s lives are sedentary? They drive to work, sit in front of a screen all day, then drive home and binge on the latest Netflix series. It’s no wonder there’s a growing epidemic of obesity and mental health issues. 

    Our bodies are made to move — so we should move them! This can be as simple as walking up the stairs to your office instead of taking the elevator, and going out for a walk around the block at lunchtime. In the evening, instead of arriving home and crashing on the sofa; spend 20 to 30 minutes walking around your block.

    When you make these things a habit, you’ll be amazed by how much better you feel. You’ll have less stress — and more energy.

    7. Be Mindful of Your Surroundings

    How often do you stop, think and appreciate the “here and now”? I’m guessing not very often. But, I understand why. Modern life is demanding and fast-paced. There’s precious little time to appreciate the small things. 

    But, if you want to live a healthy and happy life, you must break out of this trap. You can do this by allocating 15 to 30 minutes each day for mindful meditation. This could be in a park, in your garden, or even in your lounge. The trick is to focus 100% on your surroundings. 

    For example, if you’re outside, watch how the leaves on the trees blow around in the wind. By keeping your focus on this movement, you’ll clear your mind from your usual stresses and strains. This will give you brain a much-needed break. And, as well as improving your mental health; you’ll find your creativity gets a boost, too.

    8. Ask for Help When You Need It 

    No one can know or do everything. Which is why you shouldn’t be embarrassed to delegate tasks to others when needed, ask questions when you don’t have the answers, and work with partners and colleagues to clarify intentions. 

    When I first set up Lifehack, I tried to do everything myself: blog writing, website creation, marketing, financial planning, etc. However, I quickly learned that it was much better to hire some help. Not only did this inject some fresh ideas and inspiration into Lifehack — it also made the whole operation way more enjoyable!

    9. Practice Self Care 

    Are you looking after yourself as well as you should? If not, then take steps to improve your diet, exercise more, and to speak to yourself with encouraging words and thoughts. 

    The latter suggestion is often overlooked. But how you speak to yourself determines how you feel, what you believe, and what you achieve.

    10. Embrace Learning 

    You cannot transform your life without learning something new. That’s because the process of change forces you to adapt. But, many people stop learning as they get older, as they find the learning process boring and bothersome. However, it doesn’t have to be this way. It can be fun and rewarding. 

    Whether you decide to learn to play guitar or study the basics of accounting — embrace learning, and begin changing your world for the better.

    I’m sure you’ll agree that these 10 strategies are simple enough for you to start putting them into action in your life. (I suggest you begin today!) 

    Nevertheless, you’ll probably need to use some extra willpower for the first 30 days or so, as this is the typical length of time it takes to create a new habit. After that, these strategies will be part of your day-to-day life, and you won’t need to think about having to do them. In other words, they’ll have become habitual actions.

    If you need any further encouragement to get started with the 10 strategies, then consider this:

    Even just adopting one of the strategies can turn the tide in your favor. But, when you implement all 10, you’ll create an unstoppable trend towards success, health and happiness.

    So start making your life better — today!
