Jason Foley, 48, allegedly attacked Graham Foley at his home in Glasgow’s Partick on December 25 2022.
Court papers state Foley repeatedly struck Graham on the body with a knife.
This is said to have been done to Graham’s severe injury and to the danger of his life.
Foley pleaded not guilty to the single charge at Glasgow Sheriff Court.
A trial has been set for April next year by Sheriff Brian Cameron.
Foley remains on bail meantime.
