Quick Links	Slide Rules for Sale! Sorted by Type
Click to see New Hemmi, Faber Castell, Ricoh and others Click to see New Pickett Rules	NEW IN BOX, or MINT IN BOX SLIDE RULES Fresh off the WAYBACK machine. Just a few. Amazing, but true, we still have BRAND NEW slide rules. These are disappearing quickly. We have so many different kinds just now, we have split them into Pickett and Non-Pickett pages, for quicker viewing. Don't miss your chance to get a brand new rule! just as they looked in 1972. When these last few lots disappear, we do not expect to ever see any more at these very low prices. We have pooled resources from collectors *all over the world* to bring you this rich and varied assortment, but for many types, the quantities are low, and they will soon be gone forever. Featuring POST, PICKETT, UNIQUE, DIETZGEN, BLUNDELL. Note, also see the CIRCULAR section for more NEW circular rules. See the POCKET section for more NEW Pocket Rules.
Click to SEE Circular Rules	CIRCULAR SLIDE RULES The always elusive circular rules, fascinating, but they just don't last very long. Just a few new ones still available from Concise/Sama + Etani and Hemmi. Don't miss this unusual find!
BID ON LINE Click to SEE the Auctions	ON-LINE SLIDE RULE AUCTIONA monthly SR Universe feature, this site has slide rules and other related treats for auction. Fascinating and fun, could be your chance to get a fabulous treat for only a song. Duke it out over the net. NEW Auction twice a year, for the local Food Bank!
Click to SEE Pocket Rules	4"/5"/6" POCKET SLIDE RULES My favorite - computing pocket rockets. Small and elegant rules with lots of power. This section changes frequently, and we often have a pocket rule in the AUCTION, or in the PICKETT NEW IN BOX section as well. There are both new and used rules here.
Click to SEE Full Size Rules	10"/12" USED FULL SIZE SLIDE RULES Powerhouse 10" duplex rules to Mannheims. Great working or collecting rules in the standard full size format. Deci-lons, Versalogs, Deci-trigs and Polyphase rules live here. These rules are not new, but are cleaned, overhauled and restored as needed, and in very good condition. Find the rule you used to have in school!
Click to SEE Exotic Rules	EXOTIC SLIDE RULES, Chinese Abacus, ETC. You just never know what you may find here. Giant 20" Rules, and unusual special functions and seldom seen manufacturers from all over the world. Many unusual and unique items for those tired of just C and D scales.
Click to SEE Drawing and Measuring Tools	Drawing and Measuring Tools All kinds of fascinating items from Rapidograph and Leroy pens to chain rules, Lufkin caliper-rules, compass sets and architectural templates. Too interesting to miss! Makes like Koh-i-noor, K+E, POST, Dietzgen, Lufkin, Charvois, Pickett, Lietz and more.
Click to SEE New Slide Rule Cases + Pins	SLIDE RULE CASES and Tie Pins Need a new case for that slide rule? We have had custom cases made that fit most duplex and mannheim rules, and offer far more protection and wear resistance than the original factory cases. Have a look!
Click to SEE Repair Parts	SLIDE RULE REPAIR PARTS We finally have a good selection of repair parts for both sale and trade! Fix that sad, busted rule, and make it look new again. Got some extra parts to put in the exchange pool?
Click to SEE Cheap Rules	LOW COST (CHEAP) SLIDE RULES Inexpensive slide rules for training or collecting. Great first rules for bargain prices. These come and go very quickly, so check here regularly to see what's in stock. Need something simple and inexpensive to get started, or just to see how they work? This is the place! We had over 1,500 last year, just a few hundred left.
