Woodcarving chisels work by having their sharp blade forced into a piece of timber.
They can be either hand manipulated…
…or struck with a mallet.
As the chisel’s sharp blade is forced into the wood, it separates the fibres and shaves or chips off small amounts of wood.
To carve effectively and efficiently your woodcarving chisels need to be razor sharp.
A dulled or blunt blade will not only make cutting into the wood much more difficult, it will also reduce your control and increase the risk of slippage, which can lead to injury.
