Having said that, I've watched expert petrol saw operators using them to
create complex 'sculptures' out of blocks of wood - using just the tips
of the bars.

There's loads of different chains, i.e. different tip geometries. Tree surgeon
or carving chains that have little or no kickback, made to dig rotten wood in
holes or carve, or chains to cut large logs quickly. ISTR chains labelled
suitable for "diy" or "homeowner" use in the catalogs: slower cutting, less
kickback.

General rule seems to be the faster they cut, the more kickback they have.
