February, that month with the incongruently dissatisfying number of days, but know for its romance brings us the most delightful of discounts.
During the month of February, all non-US made slide rules with a base price above $25, will receive a 15% discount at checkout. Nothing says romance quite like elaborate mathematical tools, which we’re told are great for facilitating multiplication(to say nothing of the elaborate angles and functions they can handle…).
Many years ago, internationally acclaimed found-object artist Leo Sewell, used a collection of slide rules to make a unique slide rule cityscape. We recently uncovered a photo of the piece in a stack of old documents, and we are happy to share this piece of art with you here:

As we continue to work through the large stack of slide rules in our inventory we are finding rare items that were never previously listed. We’ve recently added a variety of K&E, Nestler, and Faber Castell oversize desktop rules.
These are very early design rules, often made with solid wood bodies and cellulite laminate, designed for desktop commerce applications. You can find them on our Recently Added page, by individual manufacturer, or on the search page here.
It’s been quite a while since we’ve had a chance to add more stock to our website, but we’ve added all manner of new things! Click over to the Recently Added page to see what’s new.
Don’t forget, we’re still having a site-wide sale until the end of December!
Shipping to the US has become a bit more costly over the last year, but if you are one of our US customers we have some good news for you. US origin products do not pay duties/tariffs, so if you are looking for a slide rule but may be rethinking it because of import duties, consider the following US made rules:
Don’t forget, we’re also have a site-wide 10% discount on all slide rules until the end of December, with some specific rules discounted %25 (discount applied at checkout).
