Woodcraft has some. They have both Wood River bent paring chisels and Ramuelson dog leg chisels. I have used both and am happy with them. They are easy to make though. I always grab any good quality chisels if I see them at flea markets or garage sales. If I need to make a dog leg of a specific shape, wrap the cutting edge in a wet rag, and using an acetylene torch, heat the area I want the bend and using pliers or vise grips bend away. A propane or Mapp torch often takes too long to heat up to bending temp which can screw up the temper of the cutting edge.
