You should contact Eagle claw or Yamaguchi I'm sure there is a manufacturer that would listen if they want to I can't figure out why the other ones didn't follow suit those sickle hook is probably the sharpest hook I have ever used in I do swear by it for building my jigs but we also carry a full line of Eagle claw of course the round type but I'm sure that the other manufacturers have taken a big look at this already I don't know if the sickle is patented could be a problem but they only have to change the band of the hook to make a wider gap I don't think there would be a problem there and I'm sure that they are working on this so don't be surprised in the future if you see something on the market similar to the sickle.
