Do I have to use a tenkara kebari?
In tenkara, there is what is considered the "One Fly" theory. The theory states that an angler needs only one pattern to catch all the fish that they want. This idea came from the times when tenkara was used as a commercial form of fly fishing in Japan.
Because tenkara was practiced by anglers who lived in mountainous regions of Japan in a time when fly shops did not exist materials to make flies were at a premium and this caused the anglers to tie flies using materials that were accessible to them such as the wife's needle that was heated and bent into a hook, thread that was potentially lifted from the wife's sewing box, and a feather from a chicken off of last nights dinner.
