Hagenbuch v. Snap-On Tools Corp., 339 F. Supp. 676, 10 U.C.C. Rep. Serv. (West) 1005, 1972 U.S. Dist. LEXIS 14847 (D.N.H. 1972).

Opinion

OPINION

BOWNES, District Judge.

Plaintiff Richard P. Hagenbuch brings this action for damages for personal injuries resulting from a hammer chip striking him in the left eye. He alleges breach of implied and express warranties, negligence, and strict liability in tort. His wife, Joan Hagenbuch, seeks damages for loss of consortium. Defendant Snap-On Tools Corporation was the seller of the hammer, and defendant Houdaille Industries, Inc. through its subsidiary, Fairmount, was the manufacturer of the hammer which the plaintiff was using at the time of the injury. Jurisdiction is based on diversity of citizenship and damages in excess of $10,000. 28 U.S.C. § 1332.

LIABILITY

The plaintiff purchased a BH-123 cross-peen hammer from Donald Hodgdon, an authorized salesman and distributor of Snap-On, on June 6, 1969, in Concord, New Hampshire. According to the Snap-On Catalogue, the BH-123 is “[ejxcellent for the repair work since it has plenty of ‘beef’ to handle heavy tires. Also can be used for many other jobs such as straightening frames, bumper brackets, bumpers, puller work, etc.” PL Ex. 2, p. 92. The Catalogue also states that “Federal Specs: GGG-H-86A applies to the BH-123 Hammer.” PL Ex. 2, p. 92. Plaintiff usually received one or two of Snap-On’s Catalogues each year and had perused the 1969 Catalogue. He bought the hammer for his job as a truck mechanic in Concord since it is customary for mechanics to own their own hand tools. Previously, he had purchased Snap-On tools in Manchester for his work and preferred them because he considered them to be the highest quality tools available. He did not know, however, that some Snap-On tools are not actually manufactured by Snap-On itself. In this case, the hammer had been manufactured by defendant Houdaille’s Fairmount Tool and Forging Division for distribution by Snap-On and bore the stamped mark “Blue Point.”

Plaintiff used the hammer at work primarily for driving king pins. In the summer of 1969, while using the hammer to form a channel iron bumper, plaintiff sustained a minor finger injury caused by a piece of metal. Later he noticed a chip missing from the hammer and suspected that the hammer was the source of the metal which had imbedded in his hand. He was not especially alarmed, but he did talk to the salesman, Hodgdon, about it, who told him that *678 there was no guarantee against chipping and refused to replace the hammer. 1

Subsequently, on September 19, 1969, plaintiff was struck in the eye by a small piece of steel which chipped off the hammer while he was using it with a brass drift pin to remove a king pin from the front end of a bus.

Bernard Lement, plaintiff’s expert metallurgist, examined, photographed, and tested the hammer after the accident. PI. Ex. 22. Sections of steel had been cut from the hammer, but the chipped area containing a cavity was unchanged. That area, designated J434-9, was removed at Lement’s direction and matched with the chip which had been removed from the plaintiff’s eye. Lement found that the chip fit the cavity and concluded that it came from the hammer and, specifically, that portion of the hammer head designated J434-9. Deft. Ex. A, PI. Ex. 12.

Lement then conducted hardness tests, a chemical analysis, magnaflux, dye penetrant, and microexamination tests on various sections of the head. On some portions he found long cracks which he attributed to a low forging temperature. On others, his microexamination disclosed partial decarburization. Deearburization is the removal of carbon from the surface of steel material, here a hammer head, caused by oxidation when steel is being worked on at high temperatures. PI. Ex. 24, Deft. Ex. A. The higher the carbon content' of steel, the harder it is. Complete decarburization results in ferrite, which has a very low carbon content (less than 0.02%), taking the place of the carbon on the surface of the material. Partial decarburization results in a mixture of ferrite and martensite. Martensite has a much higher carbon content than ferrite and is, consequently, a much harder material. Since ferrite is a relatively soft material, it will mushroom, work-harden, form cracks, and eventually chip as it is subjected to pressure, stress, and force. Decarburization was found at a depth of .012 inches in the cavity area and to various depths in other sections of the hammer head and, in Lement’s opinion, had an adverse effect on the hammer and was the cause of the accident. To put it another way, a significant amount of ferrite due to decarburization was present in the chipped area causing fatigue cracks which progressed with successive hammer blows until failure occurred and the chip was ejected.

Lement compared the results of his tests for decarburization with Federal Specifications, incorporated in Snap-On’s 1969 Catalogue, and found the hammer to be deficient in the following respects: although the overall carbon content was 0.78% and within specifications, carbon content was less than 0.02% in the cavity area; and the Government hardness specifications were not met in the ferrite areas of the hammer head. PI. Ex. 6.

In Lement’s opinion, the accident resulted from decarburization, and decarburization is a condition which can be detected by certain specific tests which were known to Snap-On, and eliminated or reduced by grinding the surface of the material, which Snap-On also knew.

Raymond Knudsen, Snap-On’s Director of Product Research and Engineering, testified that 30% to 40% of its products are purchased from other manufacturers and distributed by Snap-On as its own products. Some of these products, including the BH-123 hammer, are identified by the “Blue Point” mark to distinguish them from products manufactured by Snap-On itself. Mr. Knudsen admitted, however, that the ultimate purchaser would naturally assume that “Blue Point” tools were manufactured by Snap-On. Snap-On sells its products through franchised dealers, primarily to customers who use tools in their trade, *679 rather than the average home user. Accordingly, it expects its tools to be put to extensive and rigorous use.

Snap-On itself manufactures ball-peen hammers. It was, therefore, familiar with the problems caused by decarburization. It found that decarburization was a normal result of the forging process and worked out in its laboratory the grinding depth necessary to remove it. PI. Ex. 3. Random lot samples of Snap-On’s own hammers and other tools are tested for decarburization by microscopic examination and micro-hardness tests. Spot checks are occasionally made on tools received from other manufacturers, but Snap-On does not require that detailed specifications or tests for decarburization be followed by those manufacturers. Knudsen did not know whether any tests had been performed by Snap-On relative to Fairmount’s hammer specifications, but he did testify that no tests had been made in 1969 on Fairmount products. Snap-On assumed that these products were satisfactory since Fairmount had been an excellent supplier and no complaints had ever been received about the BH-123 hammer. The only test of a BH-123 hammer that Knudsen knew of had been conducted in 1965. PI. Ex. 7.

Knudsen examined the hammer purchased by the plaintiff, but could not express an opinion as to the cause of the chipping.
