wrest

[W]hen giving ley or stubble land a single furrow for a corn crop, the sock should never be so broad as the slice, but an inch or two within it; except, like the bent-sock it comes a good way back on the wrest: because this breadth of feather materially augments the draught; and, by cutting the slice clean out, before being embraced by the wrest, frequently causes it to be shot aside, in place of being turned over.
