Upon asking, Barry told me that the edges on the Yuji-twisty will not be uncomfortably sharp.

Also I asked Barry for a beamshot of the finished sample at 1 meter. I got these two beamshots, with no information about the wall distance, could be the asked for 1 meter, but I can imagine from the images that it is closer. And one looks overexposed so you can not judge the beam really well. But even taken that into account, it looks like a pretty useful and even beam to me :slight_smile:
