Dearest Woot, these are cold chisels. They are not used for either wood or stone. These are used for metalwork.
Don’t be fooled by the name! If left in the sun, these “cold” chisels can easily become very warm, even hot. Buyer Beware!
Not sure about these cold chisels, but Footprint wood chisels are high end woodworking tools. I have a full set of the wood chisels and they are made of the best Engish steel.
Dearest jwvess, check out footprint’s website. Can’t always believe what Wikipedia says.
