Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The balance sheet as of June 30, 2013, which has been derived from audited financial statements, and the unaudited interim financial statements have been prepared by The L.S. Starrett Company (the “Company”) in accordance with accounting principles generally accepted in the United States of America for interim financial reporting. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. These unaudited financial statements, which, in the opinion of management, reflect all adjustments (including normal recurring adjustments) necessary for a fair presentation, should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2013. Operating results are not necessarily indicative of the results that may be expected for any future interim period or for the entire fiscal year. The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, assumptions and estimates that affect amounts reported in the consolidated financial statements and accompanying notes. Note 2 to the Company’s Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended June 30, 2013 describes the significant accounting policies and methods used in the preparation of the consolidated financial statements. There were no changes in any of the Company’s significant accounting policies during the three months ended September 30, 2013.
New Accounting Pronouncements, Policy [Policy Text Block]	In July 2013, the FASB issued ASU No. 2013-11, "Income Taxes (Topic 740) - Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU No. 2013-11 resolves the diversity in practice regarding the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This ASU comes into effect for the first annual period beginning after December 15, 2013. We do not expect adoption of ASU No. 2013-11 to affect our results of operations or cash flows.
