How slashy is Sherlock Holmes, really?

cleolinda considers the question and discovers the answer her answer in a passage from the canonical tale "The Three Garridebs":

In an instant [Killer Evans] had whisked out a revolver from his breast and had fired two shots. I felt a sudden hot sear as if a red-hot iron had been pressed to my thigh. There was a crash as Holmes's pistol came down on the man's head. I had a vision of [Evans] sprawling upon the floor with blood running down his face while Holmes rummaged him for weapons. Then my friend's wiry arms were round me, and he was leading me to a chair.

"You’re not hurt, Watson? For God's sake, say that you are not hurt!"

It was worth a wound--it was worth many wounds--to know the depth of loyalty and love which lay behind that cold mask. The clear, hard eyes were dimmed for a moment, and the firm lips were shaking. For the one and only time I caught a glimpse of a great heart as well as of a great brain. All my years of humble but single-minded service culminated in that moment of revelation.

"It's nothing, Holmes. It's a mere scratch."

He ripped up my trousers with his pocket-knife.
