I think it's safe to say that anything producing a crimp similar to the one
Bob showed is not a pair of linesman's pliers.

There is more to an electrical connection than just physical holding power.
It has to not only make a gas-tight joint to the copper (since copper
exposed to air eventually forms copper oxide, a semi-conductor), but hold
that joint through time, heat cycles and vibration.
The advantage of solder is that it creates a huge area of gas-tight contact,
compared to the relatively small points created in a crimp to stranded wire.
