I agree creep slowly, actually the thing to avoid is ground vibration I have't noticed that they are very shy of movement. The second part is trickier, I don't think anybody's reflexes are fast enough if the snake does not agree with the knife unless you are a mongoose or Brazilian terrier.You have to creep up really slowly. put you knife down beside them for scale, then quickly take a picture before they notice.
That one is stag. I’m using giraffe bone now.Cute snake!
I like that knife you've had done there. Seen it around a few times over the years. The (oiled?) bone is really nice. Only just figured out the hump on the back of the blade ... Thought it was a frivolity at first, but clearly not once you get your eye in.
