Can squirrel body hair be used in place of a hairs mask for such flies as a gold ribbed hair's ear nymph or in place of a hares mask in general.

Also, on this weeks show of the tying bench on PBS he had some type of ceramic rake used to scrape hair off of a hares mask. He said some guy in england makes them. Has anyone heard of it or knows where i can purchase one?

Thanks alot,
