HaHa just kidding. Might be a bit premature. OTOH my 3DP FrankenSharpener prototype for shop scissors works amazingly well. Using my 1x42 Delta belt sander with a worn out (and too coarse) blue belt. Once clamped its very easy to just guide it along the table. It put a very constant, consistent bevel on the edge. My well abused Oldy's have been hand ground by yours truly so no surprise to see edge correction there. But I pre-felt penned some new-ish offshore office type scissors & it was obvious my grind was better. Bit of edge de-burring with diamond & they cut like the dickens. I kind of mucked up the clamp design & it has no angle variation (yet). Probably there is more to scissor edges than what I'm doing. I won't volunteer to do the wifes sewing shears. But for my shop stash, I'm happy

Improvements. I separated the vertical column part from the base so its a bolt on. This way I can print a few different angle variants as needed. Kind of wasteful vs a pivoting head but its simple for right now. The new blade clamp has now has a rounded foot, it holds quite secure. Really pretty easy to operate. Clamp the blade, bit of down pressure on the base, skim blade along the belt until the burr is achieved, just eyeballing the oblique profile. There is probably some science to the edge profile but plenty good enough for around the shop or house. I have not messed with Kevlar in quite a while but their angle is close to 90 & actually prefer just a bit of serrated edge (like 80# is just about right). I used hand re-grinds for a long time before buying the real ones.
