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.
A lot of factors go into choosing a backpacking knife, but I will break it down into four categories:
There are a lot of high-quality knives out there in the 1-3 ounce range. The most experienced “ultra-lightweight backpacker” I know recommends the Spyderco Dragonfly ($50). With only a 2-inch blade ...
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 ...
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.
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 ...
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 ...
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 ...
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.
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 ...
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 ...
Canada does not really have any hard and fast rules, with regard to knives. Specifically, except for lists of a few specifically banned styles they do not even mention them. And something that must be kept at the top of your mind at all times is that a knife is not necessarily a weapon.
There are specific lists and descriptions, but suffice it to say you ...
Serrations are formed on one side due to the method of manufacture (a formed grinding wheel). I suppose it would be possible to grind serrations from both sides with very careful alignment but I cannot recall seeing this on any production knives.
Single-side or "chisel grind" blades are not restricted to serrated knives. Nearly all traditional Japanese ...
I have one such a belt-pocket which I can either attach to my Haversack's waist-belt, or my own hiking pant's belt clips or the belt itself using a runner (but belt is not an option for you because you are using a nylon pant).
It depends on both (its weight and size) at the same time since having it tied up at a wrong place can injure you and/or can be ...
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 ...
A folding knife is always a great idea. I carry mine everywhere - city and backpacking. It gets used at least once a day - open a beer, cut a string of rope, cut up food, remove a thorn, open up a stubborn snack. No need thinking if it is with me or not.
Because the knife is important to me, I choose my cloths with it in mind. Cotton pants, with deep ...
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 ...
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 ...
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.
