* To make your life easier, and help you find exactly what you want, we have broken the on-line slide rule catalogs into smaller sections. Just CLICK on the icon of the rule type you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, please give them time to load.


You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan CLICKHERE.

Shipping*SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidly, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating.

* E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts or plastic body pocket slide rules in a small padded envelope by letter post. Ask Susan.

*If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.

*If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 or FAX +1 (250) 769-4106 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.

* We scoured the world looking for inexpensive slide rules for learners and classes, and came up with a large quantity to pick from. These are almost all NEW sets, note there are a few which have been used previously, but are in excellent condition.


TEACHERS, do you need inexpensive rules for classes?
We have stock set aside for this purpose, and offer it at reduced prices.
EMAIL SUSAN HERE if you need help with this purchase, and have limited or no funding.

Koh-I-NoorFull Size and Pocket Size Educational Pack
VERY LATE MODELS, BRAND NEW, Every year we try and come up with an inexpensive but high quality school set for students wanting to learn about slide rules. This year, thanks to a one-time buy in Peru of all places, we are able to provide an amazing set of both full size 27401-X and pocket sized 27103 BRAND NEW Logarex/Koh-I-Noor Trig slide rules, complete with cases and printed instructions AND a free learning pack created by the good folks at the Oughtred Society to make it possible to fully master slide rule operation on your own, or in a class setting. Both rules feature data references on the back side. The pocket rule also features both inch and cm rulers - incredibly handy! Both rules are self-documenting, with actual values (X, 1/X, etc.) rather than just random scale names, great for fast learning.

Oughtred SocietyThe Oughtred Society educational items (over 150Mb) are provided on a mini-CD (works in a standard drive). For those with no suitable drive, web links are provided to download the PDF files directly to your device via the internet. This package also includes a basic printed slide rule manual in Spanish that comes with the pocket rule, and a brochure on the Oughtred Society so you can join to learn more about slide rules. By keeping the size and weight down we can also offer FREE shipping anywhere on earth for this deal only (off-world too, if you provide the carrier details), so don't miss out on this one time special. The one price is all you pay to get it sent right to your door (typically 2 week delivery, faster Expresspost delivery is available for an additional charge).

Customer Feedback on this Pack:
hereYears ago in the 90s my father looked for a slide rule in a high street shop forgetting they were obsolescent since the mid 70s. Finally I found one for him at Slide Rule Universe and immediately enquired as to range of items, pricing and postage. The response was immediate and professional and the service superb. Within days I had a slide rule and manual shipped from Canada to my father in Hong Kong and it made his day. Thanks again to Susan at Slide Rule Universe and I shall definitely be a repeat customer.

Koh-I-Noor12" / 10" plastic body Slide Rule
VERY LATE MODEL, MINT CONDITION. NEW, mint condition Logarex/KOH-I-NOOR sets with 2 part green plastic case.

Basic Rietz format rule (has over-range scale extensions for easier operation) with added reference features. It has a black/red self-documenting scale arrangement and pale yellow slide. The slide reverse has trig (S, ST, T) scales, and the back has a treasure trove of useful data and factors. It has a slightly magnifying multi-line simplex cursor design that does area of a circle, plus some other interesting stuff like horsepower conversion. These are beautifully made rules, very well constructed. We will include basic instruction reprints, as these came bulk packed with with no manuals.

Made in Czechoslovakia, they were marketed world wide under the KOH-I-NOOR brand. We got the chance to make one big purchase of these, no more when they are gone! Great starter rule for older kids!
