These articles indicate that certain methods of picking locks can be detected. No in-depth study has been published on the types of marks left by different picks, nor to what extent tumbler composition plays in detecting pick marks. It is the purpose of this study to indicate what can be learned from pick marks on cylinder locks. This paper will attempt, through use of photographs, to demonstrate the tool marks often left on pin and disc tumbler locks by various lock picks in use today.<\/jats:p>","DOI":"10.1520\/jfs10317j","type":"journal-article","created":{"date-parts":[[2015,7,29]],"date-time":"2015-07-29T17:32:00Z","timestamp":1438191120000},"page":"656-667","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":5,"title":["The Examination of Disc and Pin Tumbler Locks for Tool Marks Made by Lock Picks"],"prefix":"10.1520","volume":"20","author":[{"given":"WG","family":"Plumtree","sequence":"first","affiliation":[{"name":"Criminalistics Laboratory 1 Criminalist II , , Los Angeles County Sheriff's Department, Los Angeles, Calif."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"381","reference":[{"key":"2025062622332391100_c1","first-page":"130","volume-title":"Locks, Safes and Security","author":"Tobias","year":"1971"},{"key":"2025062622332391100_c2","first-page":"2","volume-title":"Methods of Obtaining Locked Evidence","author":"Busch"},{"key":"2025062622332391100_c3","first-page":"3","volume-title":"An Introduction to Tool Marks, Firearms and the Striagraph","author":"Davis","year":"1958"},{"issue":"10","key":"2025062622332391100_c4","article-title":"All Too Often Things Are Not What They Appear to Be","author":"Paholke","year":"1970","journal-title":"Newsletter of the Association of Firearm and Tool Mark Examiners"},{"issue":"2","key":"2025062622332391100_c5","first-page":"9","article-title":"Locksmith Plus Police Equal Public Security","volume":"32","author":"Paholke","year":"1971","journal-title":"Locksmith Ledger and Security Register"},{"issue":"4","key":"2025062622332391100_c6","first-page":"8","article-title":"Microscopic Examination Distinguishes Between Lock Pick Marks and Marks Made by Keys","volume":"18","author":"Paholke","year":"1973","journal-title":"Keynotes, Associated Locksmiths of America"},{"key":"2025062622332391100_c7","volume-title":"Glossary of Lock Terminology","year":"1971"}],"container-title":["Journal of Forensic Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.astm.org\/jofs\/article-pdf\/20\/4\/656\/94696\/10_1520_jfs10317j.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/dl.astm.org\/jofs\/article-pdf\/20\/4\/656\/94696\/10_1520_jfs10317j.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T02:33:27Z","timestamp":1750991607000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.astm.org\/jofs\/article\/20\/4\/656\/7072\/The-Examination-of-Disc-and-Pin-Tumbler-Locks-for"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1975,10,1]]},"references-count":7,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1975,10,1]]}},"URL":"https:\/\/doi.org\/10.1520\/jfs10317j","relation":{},"ISSN":["0022-1198"],"issn-type":[{"value":"0022-1198","type":"print"}],"subject":[],"published":{"date-parts":[[1975,10,1]]}}}
