Re: Stanley Black & Decker, Inc. – 5.20% Notes due 2040

Ladies and Gentlemen:

We have acted as special counsel to Stanley Black & Decker, Inc., a Connecticut corporation (the “Company”), in connection with the Underwriting Agreement, dated August 31, 2010 (the “Underwriting Agreement”), between Barclays Capital Inc., Citigroup Global Markets Inc., J.P. Morgan Securities Inc., and UBS Securities LLC, as representatives of the several underwriters named therein (the “Underwriters”), The Black & Decker Corporation, a Maryland corporation (“Black & Decker”), and the Company, relating to the sale by the Company to the Underwriters of $400 million aggregate principal amount of the Company’s 5.20% Notes due 2040 (the “Notes”) to be issued under the Indenture, dated as of November 1, 2002 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as successor trustee (the “Trustee”) to JPMorgan Chase Bank, as supplemented by the Second Supplemental Indenture, dated as of March 12, 2010 (the “Second Supplemental Indenture”) and the Third Supplemental Indenture, dated as of the date hereof (the “Third Supplemental Indenture” and, together with the Second Supplemental Indenture and the Base Indenture, the “Indenture”), establishing the form and terms of the Notes. The Indenture provides that the Notes are to be guaranteed (the “Guarantee” and, together with the Notes, the “Securities”) by Black & Decker to the extent provided for therein.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Act”).

In rendering the opinions set forth herein, we have examined and relied on originals or copies of the following:

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions set forth below.

In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to

us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. In making our examination of executed documents, we have assumed that the parties thereto, including the Company and Black & Decker, had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and, except to the extent expressly set forth in our opinion below, the validity and binding effect thereof on such parties. We have also assumed that each of the Company and Black & Decker has been duly organized and is validly existing in good standing, and has requisite legal status and legal capacity, under the laws of its jurisdiction of organization and that each of the Company and Black & Decker has complied and will comply with all aspects of the laws of all relevant jurisdictions (including the laws of the State of Connecticut and the State of Maryland) in connection with the transactions contemplated by, and the performance of its obligations under, the Transaction Documents (as defined below), other than the laws of the State of New York insofar as we express our opinion herein. As to any facts material to the opinion expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and Black & Decker and others and of public officials.

The Underwriting Agreement, the Indenture and the Global Note are referred to herein collectively as the “Transaction Documents.”

The opinions set forth below are subject to the following further qualifications, assumptions and limitations:

(a)     we have assumed that the execution and delivery by the Company and Black & Decker of each of the Transaction Documents to which it is a party and the performance by the Company and Black & Decker of its obligations thereunder do not and will not violate, conflict with or constitute a default under (i) any agreement or instrument to which the Company, Black & Decker or any of their properties is subject, (ii) any law, rule, or regulation to which the Company, Black & Decker or any of their properties is subject (except that we do not make the assumption set forth in this clause (ii) with respect to Opined-on Law (as defined below)), (iii) any judicial or regulatory order or decree of any governmental authority or (iv) any consent, approval, license, authorization or validation of, or filing, recording or registration with any governmental authority;

(b)     the validity or enforcement of any agreements or instruments may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally and by general principles of

equity (regardless of whether enforceability is considered in a proceeding in equity or at law);

(c)     we do not express any opinion as to the applicability or effect of any fraudulent transfer, preference or similar law on any of the Transaction Documents or any transactions contemplated thereby; and

(d)     to the extent any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions of the Transaction Documents, our opinion is rendered in reliance upon N.Y. Gen. Oblig. Law §§ 5-1401, 5-1402 (McKinney 2001) and N.Y. C.P.L.R. 327(b) (McKinney 2001) and is subject to the qualification that such enforceability may be limited by public policy or constitutional considerations.

Our opinions set forth herein are limited to those laws of the State of New York that, in our experience, are normally applicable to transactions of the type contemplated by the Registration Statement and, to the extent that judicial or regulatory orders or decrees or consents, approvals, licenses, authorizations, validations, filings, recordings or registrations with governmental authorities are relevant, to those required under such laws (all of the foregoing being referred to as “Opined-on Law”). We do not express any opinion with respect to the law of any jurisdiction other than Opined-on Law or as to the effect of any such non-Opined-on Law on the opinions herein stated.

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

(1) When duly authenticated by the Trustee and issued and delivered by the Company against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Global Note will constitute a valid and binding obligation of the Company enforceable against the Company in accordance with its terms.

(2) The Third Supplemental Indenture, including the Guarantee set forth therein, is a valid and binding obligation of Black & Decker enforceable against Black & Decker in accordance with its terms.

Donald J. Riccitelli, Corporate Counsel of the Company, may rely on this opinion, subject to the limitations and assumptions set forth in this opinion, as if it were addressed to him in rendering his opinion dated the date hereof, which is to be
