So, once I'd becone reasonably proficient with the #soroban, my next step was going to be learning how to use a #SlideRule. Unfortunately, it seems as though nobody makes the latter any more.
Look for “Concise” on Amazon. They are a Japanese company that appears to be the last company manufacturing #SlideRules.
You can also check http://sliderulemuseum.com/SRM_Duplicates.shtml to “adopt” an extra #SlideRule from their collection.
Also, it’s pretty easy to find an affordable #SlideRule on EBay.
Welcome to the hobby!
@inaction_figure Will do. Thanks for the tip!
@inaction_figure They're... round?

Yup! A circular slide rule is a little unconventional, but has the advantage of never “going off scale”, where your answer is of the end of the rule. For example, when multiplying 4 by 6.
If you want a conventional, linear, #SlideRule, I don’t think anyone is still making them. You’ll have to look at eBay or ISRM. There are plenty of nice, affordable used #SlideRules to be found!
