They have not made slide rules in decades, so most of them are collectors items. Best would be to print one on legal sized paper, and cut it out, and learn the ropes. Now, if you get more serious, you could glue said paper to a thin piece of plywood, and if you get even more serious, you could 3D print one. I googled 3d printed slide rule, and now, after my morning productivity was ruined with particle systems, and my afternoon productivity was ruined with archaic calculating devices... my weekend is now ruined with trying to actually PRINT a slide rule. When are the meetings for HN addicts???

    breitling's version does seem to have c and d scales, but it seems not to have a cursor, so it looks like it can't handle the very simple example i described in https://news.ycombinator.com/item?id=40324625 https://news.ycombinator.com/item?id=40324625 without a lot of extra mental work. and how would you do a square root on it? the marketing shill splog page in your third link describes several other slide rule watches, but unfortunately it's too busy with huckster patter to explain what their capabilities are; i suspect they suffer from the same weakness

If you 3D print your slide rule and write a blog post about it, it may be a good post for HN that can destroy the productivity of many people instead of just one :) . It can be something simple like downloading the model and just printing it, or it can be your own design from scratch or something in between like a customization. Remember to take a few photos for the blog and write a short explanation, easy enough for people like me that don't use a 3D printer, and some technical details for people with their own 3D printer. Did I mention to include some photos?
