Knives
Knives are one of the most versatile tools of all times. They are used everyday in the kitchen for chopping up chicken and for fine detailing small fruits. Campers use them to cut rope and clean fish. Most soldiers and rescue personnel would not be caught without one. Some knives are kept just for the collector's value.

How do you say plastic knives in spanish?
The general, all-purpose Latin for "knife" is culter, cultri, although there are other variations, e.g. scapellum ("scalpel") or cultellus (diminutive).
However, much more common in literature is the sword, as well as the shortsword. The all-purpose word for "sword" is ensis, although this rarely appears. Far more common is ferrum, literally one's "iron" (cf. English side-iron), and the more specific gladius, a type of simple shortsword, which is part and parcel to our modern conception of a Roman centurion costume.
The earliest known knives are knapped (chipped) flint and obsidian. Early man would break or knap these rocks to create a sharp edge, much the way breaking glass gets a sharp edge.
Why is sharp knife more affected than a dull knife?
Bacause the Sharp Knife has greater pressure than a dull knife.
it cuts better because it is sharper. the force exerted on it is greater than it would be if it was blunt.
The area on the tip of the blade is small meaning the pressure exerted is all at the end of the tip making it easier to use. (the force on both knives is the same)!
Answer
When we cut any vegetable or fruit with a sharp knife suface area will be less so force applied is more and pressure will also be more (force is directly proportional to pressure). Thus,vegetables or fruits are cutted more perfectly.
Answer
It depends a bit on what is being cut and why.
Imagine trying to cut a tomato with something really blunt, like a ruler.
It wouldn't cut, but rather crush its way through, leaving a considerable mess.
The sharper the blade, the less crushing there is, and you get nicer, more useful parts from the cut.
If you're trying to cut something that's stronger/harder than fruits and vegetables, then a blunt blade would need to be pushed a lot harder against the surface before it starts to cut. If you want to do a bit of wood carving, you might simply not be able to push hard enough to get any "bite" if the blade isn't sharp enough.
Sharp knives cut better than dull knifes because sharp knifes have a thinner blade, leaving less area to cut.
Sharp knives cut neatly, without crushing cells of the food. The sharper knives also prevent cutting fingers as pressure is evenly applied and no slippage happens,
Pressure is force per unit area, sharpness implies lesser area (that makes the contact). Hence, in case of sharper blades we end up with greater pressure which helps us cut an object more effectively.
You can relate high pressure to concentrated force. So, in case of sharper blades, this concentrated force weakens the surface more effectively and hence easily cuts through.
because the blade is thinner and its easier to cut with a thinner blade than a wider blade, it all comes down to atoms and how many atoms wide the knife it, the fewer atoms wide the knife is, the easier it will be to slice through something with it.
It's easier because a sharp knife will cut through more quickly and accurately, than a blunt knife will take longer and it won't cut very well.
Because there is less surface area in contact and the force applied is being concentrated on the less area.
The same reason that it's easier to cut an apple with a sharp knife that with a blunt knife because sharp knife is very sharp and it is easy to cut but with blunt knife it is very hard
It is said that a sharp knife is better, and safer, than a dull one because with a dull knife, you have to work very hard to cut and that usually means sawing away at whatever you are cutting. A dull knife is more likely to slip and cut you because it is not easy to cut with. A sharp knife will do the job in one swipe and not much movement.
A sharp knife has a smaller edge than a blunt knife. When dealing with fracture or tearing, a smaller edge means cutting a smaller area. On a molecular scale this means breaking fewer bonds, and less energy to separate the object into pieces.
The sharp edge is the thin edge. The thinness is important because it needs to be thin to get between the molecules to 'cut'. The blunt edge is too thick to do this.
Because the knife is sharp.
Why is this question categorized in baboons?
If you apply 10 lbs of pressure on a blunt knife, the pressure's spread over the area of the knife which is in contact with the meat, where as the sharp knife has a much smaller area, making the same pressure localised, allowing cutting to be done much easier.
Maybe because its sharp
cuz.
A sharp knife has a smaller area on the edge of the blade, so you get a higher pressure with an equal amount of force. This means you can puncture the skin of a fruit with less force if you use a sharp knife.
Does putting knives in the dishwasher make them dull?
Not directly-although it could help them rust in which case the rust could help corrode the edge. Either way-you should dry them immediately after cleaning.
Which 2 metals that can be cut with a knife?
sodium and potassium are the two metals that can be cut by a knife.
What uses does a double sided knife have?
Well this is a nice random question!
Maybe you might want to spread butter on toast but you also want to spread jam on it without getting butter in the jam or vice versa.
And with the double sided knife, this would be possible.
Why is it difficult to cut vegetables with blunt knife give reason?
Because your knives are all dull. Sharp knives cut tomatoes quite easily.
What century was the knife and fork invented?
While knives have been used as tools, weapons, and even to help in food preparation-to carve up large pieces of meat, for example-it wasn't until the Middle Ages (a period ranging from roughly a.d. 500 to around 1500) that people began regularly using knives to get food from their plates to their mouths.
Why do all Butter knives ( not spreaders) have a little dip or nick in the top edge of the blade?
Steak Knives have ridges to be able for the user to saw the meat fibres easily
How do you keep a Swiss army knife sharp?
to sharpen one you can use any knife sharpener even one for a kitchen knife just put the blade in the rig and pull back if you don't hold it straight it could not sharpen or even dull the blade so be careful

Why was a knife called a jack knife?
http://www.answers.com/library/American%20Word%20Origins-cid-2228396 jackknife
Origin: 1711 Americans may not have been the first to think of making a knife safe and portable by giving it a blade that folds into the handle, but we were the first to call it a jackknife. Our earliest notice is in the official records of Springfield, Massachusetts, for 1711: "One Dozen of Jack Knives, at six http://www.answers.com/topic/pence the knife" on one occasion, and "Eleven iron handled Jack knives" on another. Jackknives were a traditional accouterment for boys who were growing up in America. Without them the playing of mumble-te-peg (an English game which antedates jackknife by eighty years at least) and the whittling of sticks (which probably antedates English and perhaps even the Bronze Age) can only be practiced by the possessors of the larger and more formidable http://www.answers.com/topic/sheath knife (1837). The practical advantage to the jackknife lies in its relatively safe transportability in one's pocket. Where did we get the term? Perhaps it came from the Scottish word for a similar knife, jockteleg knife or Jock the Leg Knife, attested as early as 1672. Or perhaps it was from Jackmeaning "sailor," since the knife was used by sailors. In modern times, the figure of a jackknife opening and closing has found application beyond the tool itself. Its name has been given not only to a style of diving (1922), but to a highway accident where a tractor-trailer truck folds in on itself. * jackknife
What is a small knife to peel fruit?
Although it may not be the preferable tool for the job, it would do the trick.
A cook's knife, also called a Chef's knife or French knife, is a large all-purpose knife that everyone should have in their basic kitchen arsenal. It's really just a modified butcher's knife, originally used to slice and disjoint large cuts of beef.
Direct counterpart of western chef's knife from Japan is a Gyuto, not santoku. Gyuto is based on French chef's knife, vs. German style chef's knife, i.e. more slander, with less belly.
Main difference between Gyuto and western chef's knives is its lighter weight thanks to its thinner blade. Steel used in Japanese knives is typically much higher quality compared to western knives and is a lot harder as well, 54-56 HRC is typical hardness of a western chef's knife, while average Japanese Gyuto will be well over 60 HRC, andhigh end knives go 65-67HRC.
Santoku, loosely translated from Japanese means"convenient knife", and more literal translation is a knife of three virtues, although it's not very clear what are those 3 virtues.
Santoku is less versatile version of a chaf's knife, but it is more multipurpose compared ot dedicated vegetable knife like Nakiri. Santokus are never used in a pro kitchen in Japan at least, mainly household cook's knife. main drawback of the santoku is the lack of length, specimens over 7" are very hard to find, and lack of belly curve.
Why does plastic chopping boards blunt knives?
Plastic chopping boards can blunt knives because the material is softer than the steel of the knife blade, which can cause the edge to deform over time. The repeated impact and friction from cutting can lead to micro-chipping or dulling of the blade. Additionally, some plastic boards can have a textured surface that may exacerbate this dulling effect. Overall, while plastic boards are gentler than harder surfaces, they can still contribute to knife wear.
What is a round knife used for?
There are many varieties of round knives, they can be called Rotary knives or circular for certain knives, but there is more, I have listed some sites:

Marking knives have a steel blade which is sharpened to a knifes edge. The purpose of the knife edge is to sever fibres as the marking knife is drawn over them.
Joe Knife.
Knives, scrapers and axes are about the oldest tools used by humans. We have absolutely no idea who first came up with the idea. The Stone Age people first had them well over one million years ago, and the first metal (bronze) knives date back some 6,000 years.
How much do Sabatier knives cost?
Sabatier knives have different costs depending on the style of knife you are interested in. The 3" parer knife costs $36.00 and the 8" wide chef knife costs $83.00. This is just a sampling of the knives available and what they cost.
How do you use a hand held knife sharpener?
Some whetstone are meant to be used with water and some with oil. In either case, hold the blade to be sharpened against the stone at the angle of the sharpened edge of the blade. Apply a little pressure and work the blade in a circular motion along the edge of the blade. Do one side and then the other then lightly do the first side a couple of strokes. How long it takes depends on the type of steel in the blade and how dull it is.
