What it is
A chainsaw chain with C-shaped cutter links that cut in one direction and are easily sharpened. Joe Cox devised it after watching a timber beetle larva boring through wood and marketed it through Oregon Saw Chain.
The beetle-larva anecdote comes from the company; Cox's patent dates to 1947.
What it led to
- felling and bucking with a durable, field-sharpenable chain
