Short answer: Very good.
There are other brands that I consider to be in the same ‘class’. Carter and Sons are made with the same steel. Thompson uses a different, but arguably just as good if not better steel, in his tools. With any of these three, what’s separates one from the others in performance is the geometry of the tool — which comes down to personal preference.
By the way, I believe Dave at D-Way is no longer making tool rests.
