What are we supposed to explain? Chainsaw can be used for wood farming and PVP, Spas-12... uhm, you know what is it, i guess. It has pretty small damage but shoots extremely fast. Spas-12 + incediary shotgun shells = true hell.

One is a tool for harvesting wood at an increased rate. It'll most likely be quite loud, and take low-grade fuel or oil to operate.
The other is a military-grade shotgun with extremely rapid fire. My guess would be it'll be a "drop-only" weapon, similar to the M92 or LR300, but I could be totally incorrect.
Nothing else to it mate.
