Kashiwagi Shigetaka (柏木重孝) has made a leather hard case sheath for a Daiwa One Touch folding net. Also replacing the original handle with an extending handle. One or both ideas might be of interest if you have a folding net.

In this 1:29 video he demonstrates his creation, hamming it up for the camera.

Tenkarabum sells a similar net made by Shimano, he also shows pictures of the Daiwa One Touch, explaining why he prefers the Shimano folding net.

A few more pictures of Kashiwagi's projects. Not enough informtion to provide how-to instruction.

I have seen Kashiwagi Shigetaka's style of Tenkara described as hybrid-tenkara. Mostly, I think, because his rods are quite outside the norm. But otherwise his Tenkara gear is very traditional. He makes a lot of different hand crafts; kebari, fly boxes, other creative tool holders, etc. Which he sells through 2 or three different websites. He is an inventive guy who follows his own drumbeat. Here is a bamboo rod cap he has made also posted on his blog.

Beyond these links to his blog he has a couple of other online commercial websites, at one time I had a link to an English language site, but can not find it or it has been taken down.

Anyway, an interesting net sheath idea.

fwiw,
