Picking the Mul\u2010T\u2010Lock cylinder with a traditional picking tool is highly complicated because it can get stuck between the inner and outer pins. The H&amp;M Mul\u2010T\u2010Lock picking tool was designed to overcome this problem and facilitate the picking of the \u201cpin\u2010in\u2010pin\u201d cylinder. The purpose of this research is to determine whether H&amp;M Mul\u2010T\u2010Lock picking tool leaves class characteristic mark and whether it can be distinguished from traditional picking tools marks and from regular key marks. It also describes and determines the class characteristic mark left on telescopic pins, its origin, recurrence, and its benefit to the toolmarks examiner. When receiving a Mul\u2010T\u2010Lock from a crime scene, a toolmarks examiner can quickly determine whether or not it was picked by an H&amp;M Mul\u2010T\u2010Lock picking tool by noticing the class characteristic mark which this typical tool leaves.<\/jats:p>","DOI":"10.1111\/1556-4029.12512","type":"journal-article","created":{"date-parts":[[2014,5,19]],"date-time":"2014-05-19T14:50:53Z","timestamp":1400511053000},"page":"1109-1112","source":"Crossref","is-referenced-by-count":2,"title":["The Class Characteristic Mark of the H&amp;M Mul\u2010T\u2010Lock Picking Tool in Toolmarks Examination"],"prefix":"10.1111","volume":"59","author":[{"given":"Nikolai","family":"Volkov","sequence":"first","affiliation":[{"name":"Division of Identification and Forensic Science Israel Police Headquarters Jerusalem 9190600 Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nir","family":"Finkelstein","sequence":"additional","affiliation":[{"name":"Division of Identification and Forensic Science Israel Police Headquarters Jerusalem 9190600 Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yehuda","family":"Novoselsky","sequence":"additional","affiliation":[{"name":"Division of Identification and Forensic Science Israel Police Headquarters Jerusalem 9190600 Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsadok","family":"Tsach","sequence":"additional","affiliation":[{"name":"Division of Identification and Forensic Science Israel Police Headquarters Jerusalem 9190600 Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,5,19]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1520\/JFS10317J"},{"key":"e_1_2_6_3_1","doi-asserted-by":"crossref","unstructured":"PaholkeAR.All too often things are not what they appear to be.
