What are the two basic nose styles for lineman's side cutting pliers?

Lineman's pliers are similar to needle-nose pliers: both tools share a typically solid, machined forged steel construction, durable pivot, gripping nose and cutting craw. The main differences are that the slender nose of the needle-nose pliers enables it to form small diameter bends, and position or support items in awkward places. Needle-nose pliers typically have a lower handle/nose length ratio, reducing the force that can be exerted at the tip. Also, needle-nose pliers tend to be available in smaller sizes (for electronics applications, they may be found as small as 1/10 scale of the full-size version).
