One of many enjoyable components of being a prepper is making your personal survival gear, devices and residential tasks. For these of us who contemplate ourselves do-it-yourselfers, there’s an actual pleasure in making issues; having the ability to make issues that may assist us survive additionally offers a really actual satisfaction. Making knives is particularly satisfying, in addition to being a helpful talent, offering a helpful survival device.
As everyone knows, a knife is the one most vital survival device. All of us try to search out that one knife, which is the proper mixture and can be utilized for all our survival wants. In actuality, no such knife exists, largely as a result of totally different blade sizes and styles are helpful for various issues. Cooks don’t have only one kitchen knife. Following that instance, it actually makes extra sense to personal a number of knives that are created particularly for every goal that we would want, together with a general-purpose knife or two.
Shopping for all these knives will be quite costly, particularly if we’re going to purchase high quality knives; and it actually doesn’t make any sense to purchase knives that aren’t high quality. It’s truly cheaper to make them your self, which additionally offers you the chance to experiment with knife design, in addition to the bragging rights to say that you simply made it your self. So, the query is, how do you make a knife?
It Begins with an Thought
Earlier than even searching for metallic to make use of, you wish to sit down and draw out the form of the knife you wish to create. Truly, you wish to draw out a bunch of knives, experimenting with design, till you provide you with one thing you actually wish to make. Your sample will be on paper, however I wish to put them on thicker cowl inventory. It’s simpler to hint across the cowl inventory, than to hint round extraordinary paper.
One factor you undoubtedly wish to do is to make your design a full tang knife blade. The metallic from the blade wants to increase all the best way although the deal with to provide it power and maintain it from breaking off. This doesn’t imply that the tang has to increase all the best way to the outer edges of the deal with, however that’s what’s mostly carried out.
You’ll Want Some Steel
Making any knife begins out with a metallic clean. Blacksmiths are in a position to forge these blanks and factories begin out with blanks they get from the foundry. You and I don’t have these choices, though it’s doable to purchase knife blanks on-line. It’s even doable to purchase Damascus metal knife blanks. If you happen to’re searching for a reasonably knife, that’s one thing you would possibly wish to attempt; however should you’re searching for useful, you’re higher off with different metal. The Damasus metal they promote right this moment is extra ornamental, than the stuff of fame and legend.
Apart from shopping for knife blanks, there are a number of actually good sources to think about. You desire a good device metal or spring metal to work with. These will be discovered both in outdated blacksmith’s rasps, leaf springs from vehicles or outdated noticed blades, reminiscent of round noticed blades. The noticed blades are solely helpful for skinny blades, as they aren’t very thick; however there are some locations the place a skinny knife blade is admittedly helpful.
It will likely be essential to chop a clean out of the obtainable metallic. That is normally greatest in two phases. The primary stage is a rough-cut, to get a bit of metallic that’s roughly the fitting dimension. The sample can then be traced onto that, in order that the knife’s define will be lower.
So, how do you chop the metal to make a knife out of? If in case you have a band noticed, don’t attempt it. Even the very best band noticed isn’t going to work. You’ll want to make use of abrasive slicing, particularly abrasive slicing with a blade or grinder wheel that’s made for slicing metallic. Most DIY knife makers use a right-angle grinder, though a cut-off-saw is less complicated for lots of the cuts. Lower-off saws can be found for significantly decrease price than miter saws, as a result of they’re simpler.
One factor that’s extraordinarily vital about making any knife is to keep away from overheating the metallic. So long as the metallic doesn’t overheat, it retains its mood. However as soon as it overheats, it’ll must be tempered once more. If the metallic turns crimson, it’s too sizzling. So, the key is to chill the metallic by quenching it in water or oil, as quickly because it begins turning crimson, earlier than it reaches that time. So long as you persistently quench the metallic whereas engaged on the knife, you gained’t have to re-temper it.
Grinding the Blade Profile
As soon as the knife clean is roughly lower, switch the sample to the clean. This may be carried out with a marker or scribe, however it might be arduous to see when you’re engaged on the knife. Your greatest wager is to make use of Metal Blue Format fluid, which will be bought from any industrial provide, Amazon.com or Ebay.com. Brush it onto the metallic and permit it to dry (it’s quick drying).
It’s simpler to grind the define first, earlier than engaged on tapering the blade. This will both be carried out on a bench grinder or belt sander. Whereas individuals who make knives on a regular basis use some fairly fancy belt sanders, with some fairly fancy costs, I’ve efficiently floor knives on a 1” extensive, $49.95 belt sander from Harbor Freight (truly, I feel it was $39.95 again once I purchased it).
Grinding the Blade
Tapering the blade is the touchiest a part of the operation. It may possibly both be carried out on a belt sander or bench grinder. In both case, you might want to confirm that the desk or stage is strictly perpendicular to the slicing floor, earlier than beginning. Use sq. for this, making no matter changes are essential and locking the desk or stage in place.
The essential distinction between utilizing a belt sander and utilizing a bench grinder is the blade profile you find yourself with. A belt sander will present a flat grind, whereas a bench grinder will present a hole grind. I’ve carried out each, and it’s tougher to do the hole grind on the bench grinder.
Begin by marking the midpoint of the fabric thickness, offering your self a tenet to work in direction of. You’ll additionally wish to mark how excessive up the edges of the blade you’re going to grind, in addition to how far again from the purpose. As soon as once more, it’s greatest to do all this marking with the Metal Blue Format Fluid for optimum visibility.
Most knifes have a 17-to-20-degree bevel, between the 2 sides. If a sharper bevel is desired, the knife is normally solely beveled on one facet. A 20-degree bevel means 10-degrees on both sides. So, a help block shall be wanted that can maintain the blade at this angle. This may be product of scrap wooden, ideally a hardwood. Don’t attempt holding the knife by hand, as it will likely be all however unattainable to carry it at a constant angle.
To make use of the knife help, connect the clean to it with double-sided masking tape, masking as a lot of the knife clean with tape as doable. The warmth from griding will soften the tape’s adhesive, therefore the necessity to use quite a lot of tape. Lay the bottom of the help on the stage or desk and transfer the clean as much as make contact with the belt or wheel. Then transfer it forwards and backwards, grinding the blade.
The true key right here is how you progress the knife clean. You wish to be grinding the complete slicing space of the blade on every go, not engaged on one space after which transferring to the following. Engaged on the complete facet on the identical time is important to create a good bevel alongside the blade. It additionally helps in stopping overheating of the metallic, as the assorted factors alongside the blade have time to chill throughout every go. Cease usually and quench the blade to maintain it from overheating.
You aren’t truly going to be grinding all the best way to the middle line, however stopping simply wanting it. The ultimate grind shall be carried out by hand on a rough whetstone. Nonetheless, the nearer you may get to that heart line, the much less you’ll must grind in your micro-bevel.
You’ll be able to both do the hand grinding and sharpening at this level, or wait till the grips are mounted to the blade.
Making the Grips
Knife grips or scales will be made out of quite a lot of supplies, however they’re mostly made out of wooden on do-it-yourself knives. Use the tang of the deal with itself as a sample for the scales, as your ultimate knife blade won’t match your unique sample precisely. Lower the handles barely oversize, in order that ultimate shaping will be carried out after they’re mounted to the blade, making certain a clean contoured floor.
The mating sides of the scales should sit flush on the edges of the blade. Earlier than mounting them, examine their match and airplane or sand them as essential. To connect the scales to the blade, two to 3 holes will must be drilled by means of them and the knife blade’s tang. These must be completely aligned and sized for drive pins (ideally brass, however different supplies can be utilized) to carry them collectively.
It’ll probably be extraordinarily troublesome to drill these holes by means of the knife blade, because the metallic is hardened. Use a drill press, if obtainable. That can assist forestall bit wandering and give you extra leverage. Take your time, working up from a smaller drill bit and utilizing oil to lubricate and funky it.
As soon as the holes are drilled, the drive pins can be utilized to connect the scales to the edges of the knife blade. Generally, you’ll wish to use some adhesive as properly, reminiscent of epoxy. Enable the adhesive to completely remedy, earlier than slicing off any further pin size and starting to form the knife deal with.
Relying on the design of the deal with, it may be formed with a router, mounted in a desk, a belt sander or a drum sander. A very powerful factor is to make it clean and cozy in your hand, whereas eradicating any burrs which may scratch or lower you. Sand every little thing clean and end the wooden with both varnish or clear epoxy.
