When I Hear The Term 'Wood Carving',

I think of small hand tools like chisels being used,

 to produce carvings like these, some bold,

others delicate,

 so it comes as a surprise to learn instead of chisels, Simon O'Rourke uses a chainsaw! 

 he uses not only blocks of wood,

but also incorporates his work into living trees, you can see more of his work on his Facebook page, amazing.
