Cold chisel

Why do they call a "cold chisel", a cold chisel?
I have always found this a very useful tool.
I know there are a lot of machinists that visit this site. Is it because it is cold forged? Thanks for all your answers in advance.
 
Cold chisels are made of steel (usually) that is tempered with the intent that it be used to cut cold metals. Sometimes they will be made of non-sparking metal for certain applications but the intent is always that they be used to cut cold metals. As opposed to wood chisels, masonry chisels, etc.
They are made in various shapes. There is also a "hot" chisel usually used in combination with an anvil. Ever hear of a "hardy" chisel? Or, the "hardy hole"?

Probably anyone who's owned an anvil or done any 'smithing knows about hardys. There was a thread a few days ago........maybe on the tools phorum........ about the 'best' cold chisel. I went through a fase:>) a few years ago making a phew knives and some chisels. Good quality crowbars.......which could be had for not-a-lot-more money than a good quality chisel....... was the basis for my chisels. Also made some boat slicks out of leaph springs which I was particularly proud oph. May have some pictures, but they're not on this computer.
 
:>) ...........we used those things .......maybe it was buggy axles??........to drive into the ground to mark corners or change oph direction oph property lines. You haven't lived 'til you've dealt with the 'meets and bounds' system of surveying.
 
A "hot" chisel isn't a hardy chisel. A hot chisel is used either held in the hand like a cold chisel or it may have a handle on it, it's still struck with a hammer. The cutting angles are different.

Look through some blacksmithing books or catalogs.
 
Well, Bill(Wis) is responsible. He instructed us to make the change. I was conphused and didn"t (still don"t) really understand, but......either we"re running short of "fs" and need to substitute "phs" when at all possible, or he"s stockpiling "fs" for some phuture use, which will be made known to us at some phuture time. It"s possible that there"s only a phinite number of "fs" available..........

LOOOOOOOOOOOOOONG time ago, there was no distinction.... a chisel by any shape or form was just a chisel.
Then, one Cold, Cold day Bubba and Marcel was out working on the car and had a bunch of chisels in the toolbox. When they set the toolbox up on a snow bank to get it closer to the car, a few of them fell out on the snow/ice. Later on, Marcel told Bubba to get him a chisel. Bubba started fishing and handing until Marcel got frustrated with getting the wrong one and pointed to a big fat one laying on the snow and said "that one ya dummy". Bubba grabbed it and, not having any gloves on, yelped "dam! that's a Cold Chisel......

Wanna hear about Nacho Cheese????????

As has been mentioned, a cold chisel is intended to cut "cold" (room temperature or thereabouts) metal and typically has a more obtuse angle. A hot chisel MAY be a Hardy chisel (made for the Hardy hole in an anvil) but it may also be hand-held (which is rather rare) or have its own handle (which is more common), and in all cases is made to cut hot metal. It typically has a narrower angle than a cold chisel. In the case of a handled hot chisel, it is typically held against the metal to be cut and is struck with a hammer or sledge, rather than being swung by itself.
 
Ihave a couple of crow bars that are made from buggy axles. I also have one chisle made from a model A axle. They are tough.
