IntroductionKraeuter & Company was an early tool maker, established in the mid nineteenth century and probably best known for their high quality pliers. Company HistoryKraeuter & Company was established in 1860 and incorporated in 1907, and is probably best known as a maker of high quality pliers. Its products included pliers, chisels, punches, striking tools, wrenches, and other specialty tools. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Slip-Joint Pliers | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
305-7 "Victor" Slip-Joint PliersThe overall length is 6.6 inches. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
356-6 Slip-Joint Combination PliersFig. 2 shows the Kraeuter No. 356-6 slip-joint pliers, stamped "Kraeuter & Co." and "Newark, N.J. U.S.A." on the handle, with "Forged Steel" forged into the underside of the handles. The overall length is 6.6 inches, and the finish is nickel plating. The handle pattern for these pliers is a dimpled field with a central diamond. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
356-6 Slip-Joint Combination Pliers with "Don't Slip" PatternFig. 3 shows a later version of the Kraeuter 356-6 pliers, with the company name stamped on the side and "Kraeuter U.S.A." forged into the underside of the handles. The overall length is 6.5 inches, and the finish is nickel plating. The handles are forged with a geometric pattern referred to as "Don't Slip" in the 1939 catalog. This pattern was registered as design patent #D46,682, issued to A.A. Kraeuter in 1914. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
356-8 Slip-Joint Combination PliersFig. 4 shows the Kraeuter model 356-8 pliers, with the company name and "U.S.A." stamped near the pivot. The overall length is 8.1 inches, and the finish is nickel plating. These larger pliers have a three working positions for the slip-joint mechanism. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1863-9 Slip-Joint Gas and Burner PliersThe standard "gas and burner" plier design incorporated rounded gripping surfaces for holding pipes, plus a smaller grip on the nose for adjusting burners. These models were generally made with a fixed pivot, and an example of the standard design can be seen in the Utica 1300 Gas and Burner Pliers. Fig. 5 shows a rare pair of Kraeuter 1863-9 slip-joint gas and burner pliers, marked "Kraeuter U.S.A." on the underside of the handles. The overall length is 8.9 inches, and the finish is nickel plating. Kraeuter has extended the basic design by adding a slip joint, a wire-cutting slot, and a screwdriver blade at the handle end. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
The Kraeuter 1863-9 pliers were listed in the 1922 C.W. Marwedel industrial catalog, at a price of $18.20 per dozen. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1973-5 1/2 Slip-Joint Combination Pliers with Side CuttersFig. 6 shows a pair of Kraeuter model 1973-5 1/2 slip-joint pliers with side cutters, marked "Grip-Kut Junior" and "Pat. Pending" on the reverse (not shown). The overall length is 5.6 inches. The finish is nickel plating. The handles have a forged-in "Kraeuter U.S.A." marking on the inside surface, as shown in the lower inset. The 1939 Kraeuter catalog lists this model as a combination side cutting plier, and refers to the handle pattern as the "Don't Slip" design. A larger 1973-7 model was also available (see the next figure), and pliers with smooth handles were available as models 1972-x. The patent corresponding to the pending marking has not been found yet. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1973-7 Slip-Joint Combination Pliers with Side-CuttersFig. 7 shows a much later pair of Kraeuter model 1973-7 slip-joint pliers, marked "USA" on the handle. The overall length is 7.5 inches, and the finish is plain steel. The handle pattern resembles the "Don't Slip" pattern seen in the previous figure, but has now been greatly simplified. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
40-6 Slip-Joint Thin-Nose PliersFig. 8 shows a pair of Kraeuter model 40-6 slip-joint thin-nose pliers, marked "USA" on the handle. The overall length is 6.4 inches, and the finish is nickel plating. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
351-7 Slip-Joint Brake Spring PliersFig. 9 shows a pair of Kraeuter model 351-7 slip-joint brake spring pliers, marked with the company name and model number, and with "Pat. Appl'd For" on the reverse. The overall length is 6.4 inches, and the finish is plain steel. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Fixed-Pivot Pliers | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Kraeuter "US" Fence-Cutting PliersThe next two figures show examples of Kraeuter wire-cutting pliers, believed to been made as fence-cutters for the military in the first World War. Fig. 10 shows an earlier pair of Kraeuter wire-cutting pliers. The pliers have forged-in markings "Kraeuter & Co. Inc." and "Newark NJ" with a "Pat Pend" notation, and the letters "U" and "S" on both sides. The overall length is 11.0 inches, and the finish is plain steel. The pliers have the cutting edges placed very close to the pivot pin, which together with the long handles would provide the leverage needed for cutting hard wire. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
The patent for these pliers has not yet been found after a fairly extensive search. The next figure shows another example of this model, but marked "1918" instead of the pending notation, suggesting that the patent might have been issued in 1918. If any readers know the patent number, please let us know via the "Contact Us" link on any page. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Fig. 11. Kraeuter "US 1918" Wire-Cutting Pliers, with Insets for Side View and Marking Detail, ca. 1918.
Fig. 11 shows a somewhat later model with forged-in markings "Kraeuter & Co. Inc." plus "U.S." and "1918". The overall length is 11.0 inches. The finish is plain steel with extensive pitting due to rust. (The pliers were electrolytically de-rusted.) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Early 1841-8 Button's Pattern PliersFig. 12 shows an early pair of Kraeuter "Button's Pattern" pliers in the 8 inch size, marked "Kraeuter & Co." near the pivot, and with "Forged Steel" forged into the underside of the handles. The overall length is 8.2 inches, and the finish is polished steel. The model number is not marked on this early example, but these pliers are listed as Model 1841-8 "Button's Pattern" pliers in Kraeuter catalog No. 15 and others. The Button's design featured both flat and rounded gripping surfaces, plus three cutting notches at the sides and center. The handle pattern has a dimpled background with a central diamond, and the diamond is stamped with the Kraeuter "K" initial. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1801-8-1/2 Lineman's PliersThe next figures show two generations of the Kraeuter 1801-8 1/2 Lineman's Pliers. Fig. 13 at the left shows an earlier pair of Kraeuter 1801-8 1/2 lineman's pliers, stamped "Kraeuter & Co." and "Newark, N.J. U.S.A." over the pivot (see lower inset). A forged-in marking "Forged Steel" appears on the underside of the handles, as shown in the middle inset. The overall length is 8.6 inches, and the finish is black oxide. The upper inset shows a side view of the pliers, illustrating the dimpled handle pattern with the central diamond. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
Fig. 14 shows a much later example of the Kraeuter 1801-8 1/2 pliers, stamped with the company name and "USA" over the pivot. The overall length is 8.4 inches, and the finish is black oxide. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1831-6-1/2 Electrician's PliersFig. 15 shows a pair of Kraeuter 1831-6-1/2 electrician's pliers, marked "Kraeuter & Co." and "Newark, N.J. U.S.A." near the pivot, and with "Forged Steel" forged into the underside of the handles. The overall length is 6.6 inches, and the finish is black oxide. The top inset shows a side view of the pliers, to illustrate the head design and handle pattern. The dimpled handle with a raised diamond logo (called simply "knurled handles" in catalogs) is believed to be one of Kraeuter's earlier handle patterns. This model was listed in the 1925 Dunham Catalog in nominal sizes of 4, 5, 6-1/2, 7, and 8 inches. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1831-7 Lineman's PliersThe overall length is 7.2 inches, and the finish is black oxide. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

U.S.A." near the pivot, and with "Forged Steel" forged into the underside of the handles. The overall length is 6.5 inches, and the finish is nickel plating. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
K-Diamond 1380-7 Lineman's PliersIn later years Kraeuter introduced the "K-Diamond" line of economy tools, a selection of popular styles produced with simpler finishes to allow lower prices. Fig. 18 shows an example of the K-Diamond line, a pair of Kraeuter 1380-7 lineman's pliers, stamped "Newark, N.J." near the pivot with the K-Diamond logo in the center. The reverse is also stamped "USA" (not shown). The overall length is 7.0 inches. The finish is black oxide, with pitting on the surface due to rust. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

This style of pliers has a flat wide tip and was recommended by the Kraeuter catalog for electrical work. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1591-4 1/2 Milliner's Flat-Nose Pliers with Side Cutters
Fig. 24. Kraeuter 1591-4 1/2 Milliner's Flat-Nose Side-Cutting Pliers, with Insets for Side View and Detail.
Fig. 24 at the left shows a pair of Kraeuter 1591-4 1/2 Milliner's flat-nose side-cutting pliers, marked "Newark, N.J. U.S.A." near the pivot, and with "Forged Steel" forged into the underside of the handles. The overall length is 4.4 inches, and the finish is polished steel. The handles have a dimpled pattern with a central raised diamond, and one handle is drilled for a hanging loop, as shown in the lower inset. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Fig. 28. Kraeuter 1850-5 "Giant Nipper" 5 Inch End Nippers, with Insets for Side View and Marking Detail.
Fig. 28 at the left shows an early pair of Kraeuter 1850-5 5 inch end nipper pliers, somewhat amusingly marked as "Giant Nipper" near the pivot, and with "Kraeuter" and the model number on the reverse. The handles have "Kraeuter, U.S.A." forged into the underside (see middle inset). The overall length is 5.5 inches, and the finish is black paint. The top inset illustrates the Kraeuter "Don't Slip" geometric pattern on the handles. This pattern was registered as design patent #D46,682, issued to A.A. Kraeuter in 1914. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

WrenchesKraeuter produced a distinctive line of open-end and S-shaped wrenches with carefully forged raised-letter markings, including the K-Diamond logo. The wrenches were polished flat after forging to highlight the markings, giving them a striking appearance. But as carbon-steel tools, these fine wrenches were rendered obsolete by the alloy-steel tools developed in the 1920s. Although the manufacturing dates are not known, this style of Kraeuter wrenches were listed in the 1925 Dunham Catalog. The figures below will show examples of these wrenches. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
A1416 Open-End WrenchFig. 37 shows our first example, a Kraeuter A1416 7/16x1/2 open-end wrench, marked "Kraeuter U.S.A." with the K-Diamond logo. (In subsequent figures we'll call this the "standard Kraeuter marking".) The overall length is 5.0 inches. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
A1619 Open-End WrenchFig. 38 shows a Kraeuter A1619 1/2x19/32 open-end wrench with the standard Kraeuter markings. The overall length is 5.6 inches, and the finish is plain steel. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
A1820 Open-End WrenchThe overall length is 6.1 inches. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

B2832 S-Shaped Open-End Wrench | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
O1820 Tappet Wrench | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
K9/16 Single-Offset Box-End WrenchFig. 48 shows a very rare Kraeuter model K9/16 size 9/16 single-offset box-end wrench, marked "Made in U.S.A." on the round shank. The overall length is 10.9 inches. The finish is chrome plating with polished ends, now mostly worn away. This wrench is a bit of a mystery, as Kraeuter is not known to have made box-end wrenches of this type. Single-offset box wrenches enjoyed some popularity during the late 1920s and 1930s, but had been discontinued by most manufacturers by 1950 or before. A 1939 catalog from Kraeuter listed mostly pliers and striking tools, but only a few of the older carbon-steel wrenches. Thus it's not clear when (or why) Kraeuter would have produced this wrench. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Scraping and Striking Tools | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1202-13 Bearing ScraperFig. 49 shows a Kraeuter 1202-13 bearing scraper with a wooden handle, stamped "Made in USA" and "Patd. 3-09-10" on the shank. The overall length is 12.7 inches, and the finish is plain steel. The patent date refers to patent #953,171, filed in 1909 by A.A. Kraeuter and issued in 1910. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Catalog CoverageProduct information was obtained from several Kraeuter catalogs, No. 15 of 1934 titled "Kraeuter Automobile & Mechanic's Tools", a 1939 publication titled "Kraeuter High Grade Tools", and catalog No. 20 of 1946. The catalogs note that the company was established in 1860 and incorporated in 1907, and list their address as 569 Eighteenth Avenue, Newark, New Jersey. Kraeuter tools were sold through industrial and automotive distributors, and the catalogs of these companies provide descriptions and illustrations of the tools available at that time. The list below shows a sampling of these distributor catalogs.
