It can be used for sure, but there are better options. A knife would require you to be very close to the dog, whilst a stick or pepper spray would provide much greater distance between you and the threat.
Pepper spray is used by the US Postal Service, and they have lots of experience with dog bites.
Of course, if you can avoid aggressive dogs in the first ...
Your primary objective when defending yourself against stray dogs is not to kill the dog, but to
avoid getting bitten
make the dog leave you alone
If you fight a dog with a knife, even if you manage to kill it or make it run away, you will likely get a few bites and scratches. Having a stick or pepper spray is a much better option, as it gives you a range ...
Try to slice a piece of paper. A good sharp knife makes a clean cut. A dull knife makes either a ragged cut, or worse, just pushes the paper to the side. I like this article: https://www.fieldandstream.com/articles/hunting/2014/08/paper-cut-testing-blade-sharpness#page-4 and YouTube is full of videos of people showing off their knives via this test.
The tool has two purposes.
As a punch, it acts as a large needle. You can use it to sew leather or canvas, as mentioned in the other answers. Punch the tool through your fabric, put thread through the hole, retract the tool, repeat.
As a reamer, the non-uniform blade shape allows you to make quite good circular holes in plastic or wood. Punch the tool ...
The back of a fingernail can be a good rough indicator while you're sharpening - see if it "catches" when you apply very gentle pressure at ~45 degree angle. This can also be a good way to check if the edge still has any dull spots.
Knife is not a good idea. It does not give an understandable warning to an animal. When it comes to a warning, they more likely understand a stick-shaped thing. So for carrying, light telescopic baton is more suitable (or any other stick you can comfortably carry around). Remember, at the first place, you want to repel oncoming animal, not to harm it.
When mine gets too bad I use WD40 to free it up, then clean with soapy water and a brush. Mine also goes through the dishwasher sometimes, with the blades partially open. If it gets gummed up with sugary stuff (your candy, or cutting up fruit) a good soak in hot water will free up the blades.
After cleaning it is a good time to sharpen it. If the hinges ...
It "looks cool" (to some)
Cordage (but arguably useless as you have noted)
Poor grip (compared to leather and manufactured alternatives)
More likely to cause blisters
Less durable, requires more maintenance
PITA to clean if it gets messy/dirty/sweaty
Once you unwrap the cord to use it, your knife has even worse grip.
IMO - It's a ...
The best method in my opinion is one that must be learned, and involves moving your thumb across the blade, perpendicular to the blade not down it! It's very difficult to describe the feeling but if you do it on enough dull blades and sharp blades you will begin to be able to tell the difference.
One other thing I will do if im sharpening a knife for a ...
It's a line cutter, the idea is that you use it to cut lines, string etc. The reason that it's curved is to keep the line from slipping off the blade, using the rest of the blade would be quite difficult to do.
See here for more examples.
You wouldn't want to use it for skinning.
Generally I categorize sharpness into 3 levels:
The tomato test - being able to slice through a tomato skin. Not use the pointy end to break the skin and then slice but directly slice the skin all the way through. This is sharp enough for cooking.
The paper test - being able to slice thin phonebook paper or magazine paper or newsprint. For general carving ...
My advice is to always use the entire length of the the stone, to make sure wearing is even, and it's easier to be slow and steady.
Also, some good information on cooking.SE.
How often you sharpen depends on how often you use them and the type
of steel. I use Globals and Mundials and the Globals require much less
Here's a ...
Slice a tomato with very little pressure. This is almost always when I notice a knife needs sharpening, and the difference is profound.
Edit: I should have added ripe tomato; a sharp knife will slice it, whereas a dull one will smash it or rumple and tear its skin.
Think of felling a tree with a hatchet or axe. The V-shaped 'incision' is a (rather rough) oversized V-notch.
On this picture, the notches on the lower side of the logs are v-notches; an illustration of stacking with v-notches.
Now, if you have a (round) stick and with your knife carve or baton a v-notch, the diameter goes down where the notch is, and so a ...
A multi-tool or a knife?
A multi-tool can be a very appropriate tool for backpacking. It combines the function of many of the tools you mentioned. You may carry the tools you mention above, though. (Note: I've NEVER needed a bottle opener...)
If you mean a knife, read on...
I do a lot of backpacking in the Eastern US, so I am going to assume that this ...
The producer offers a page of care instructions on their website (here) (PDF). The gist is:
don't use a dishwasher, that might be too aggressive
open and close the blade multiple times in warm water
put some oil on the friction points (where the blades rotate), open and close multiple times
@chris-h's answer is also spot on. I, too, use a ...
From personal experience with packs of stray dogs, especially coyotes, and also having some strange experience, carry a walking cane or staff (if you can).
Dogs, while attacking as a pack, or thinking about attacking, try to do three things:
Find easy prey
Limit prey mobility
Attack prey blind spots
Keeping this is mind, stay moving to wherever it is you’...
Ordinary vegetable oils of the type used for cooking will work but are not ideal. Over time they will gradually oxidise and may be colonised by bacteria, both of which can cause them to become acidic which can itself cause corrosion of the metal. Also vegetable oils can become gummy and sticky in quite a short period of time.
Oils help to prevent ...
As a kid we often went on hiking trips and I got my first knife when I was around eight to ten years old. Below are some of the things my parents looked out for when I was a child. Obviously this is addressed at an even younger age than OP described, so you might have to adapt it accordingly...
For beginners either get a fixed blade, or one ...
The tool pictured is riveted together with solid rivets. It is not designed to be repaired, as mentioned in a comment, if it is not working correctly it should be disposed of and replaced.
It is possible to use a grinder to remove the flared head of the rivet and then punch it out. Alternately you can drill out the rivet, by drilling a hole in the exact ...
Unless you sever the spinal column near the top of the body there is no body injury that can be done with a knife that is going to result in instant death/disablement of any animal.
Any injury that does not completely disable the animals neurological system is going to be dependent on the animal bleeding to the point that they become unconscious. Even if ...
You need to use a sharpening rod.
Example: AC134 Smith's Pocket Pal Multi-Function Knife Sharpener.
The rod just slides in the groove and sharpens it.
Here is another sample:AS028C AccuSharp 4-in-1 Knife & Tool Sharpener.
And an image from Amazon:
You are right about using the rough side first and then some polishing with the finer side.
Holding an angle is a real tricky part and needs some stability and skill.
To prevent the blade from getting damaged, you can run an ink marker over the cutting bevel. This way you'll have a reference to manage the amount of tilt you need to have. The typical angle ...
I think it can be a matter of personal taste, however:
Some people craft their own knifes, and using a paracord wrap as handle is easy to do, and easy to redo. There are some more and some less good looking wrap styles - again, personal taste.
This also applies when it comes to knifes you buy in a store. Some may like the paracord wrap just as you like ...
The next time a Gun & Knife show or an Outdoor Gear show comes to your area, take the knife. Visit a vendor who is selling knife sharpeners and giving demonstrations. Use the line,
Your sharpener won't be able to get THIS knife sharp.
If the knife comes out sharp, then buy the product. You will then have a sharp knife and a method to keep it that ...
Some places I travel to have stray dogs in the city. Can a knife be used effectively if attacked by one or more of them? I've had creepy close encounters.
Probably, but it's far from ideal. The reason you explicitly mention a knife is because you're a human who knows about knifes. You know they're sharp and they can hurt you and others. When someone near ...
