Rules:
Normal Sudoku rules apply.
Normal Lockout Line rules apply: Digits in directly connected Diamonds must differ by 4 or more and may not be repeated on the line. Digits on a line must fall 'outside' the range defined by their diamonds. Line digits may repeat if allowed by other rules. All lines go straight.
Normal Anti-Knight constraint: Cells that are a chess knight's move apart must not contain the same number.

Enjoyed this one a lot. I found it a great intro to an unfamiliar constraint. Thank you Raumplaner!

My first Lockout Line puzzle solve. Very nice and given the length of the lines, probably a great one to start on. Thanks!
