Hi Bob. I did that too, but someone posted to me here and said, PUT that swivel knife flat, if you want to cut at an angle get and angle knife, LOLOL.
I'm putting up the picture we were talking about at the time because oddly enough, I had this on a wall hanging 20 or so years ago and like your friend, I've wanted it again but never could find it. I did a search and found this at a tattoo shop, the original picture I mean. So I hand drew this, carved it, but you can see how my 'sharp' turns are. When I have time I'm going to do it again, and again until I have another wall hanging that looks like the original. Cheryl
