Z\u00e1kladn\u00ed vlastnosti RockJumperu jsou v souladu s mnoha lehk\u00fdmi zaklada\u010di Spyderco japonsk\u00e9 v\u00fdroby: \u010depel z nerezov\u00e9 oceli VG10 s pln\u011b ploch\u00fdm brou\u0161en\u00edm, pln\u011b p\u0159\u00edstupn\u00fd kulat\u00fd otvor s ochrannou zn\u00e1mkou, v\u00fdb\u011br konfigurace PlainEdge nebo SpyderEdge, skeletonizovan\u00e9 vlo\u017eky z nerezov\u00e9 oceli, robustn\u00ed lockback mechanismus, vst\u0159ikovan\u00e1 rukoje\u0165 z nylonu vyztu\u017een\u00e9ho sklen\u011bn\u00fdmi vl\u00e1kny (FRN), vysoce p\u0159ilnav\u00fd dvousm\u011brn\u00fd texturov\u00fd vzor a \u010dty\u0159polohov\u00fd kapesn\u00ed klip. Jakkoli to m\u016f\u017ee zn\u00edt \u201estandardn\u011b\u201c, skute\u010dn\u00e9 kouzlo tohoto designu spo\u010d\u00edv\u00e1 ve zp\u016fsobu, jak\u00fdm jsou vyj\u00e1d\u0159eny v\u0161echny tyto osv\u011bd\u010den\u00e9 vlastnosti.<\/p>\n

Jedn\u00edm z prim\u00e1rn\u00edch designov\u00fdch c\u00edl\u016f RockJumperu bylo zabalit co nejv\u00edce \u0161pi\u010dkov\u00e9ho vybaven\u00ed do jeho kapesn\u00ed velikosti a p\u0159itom st\u00e1le vyu\u017e\u00edvat st\u0159edov\u00fd z\u00e1mek. Prodlou\u017een\u00e9 ost\u0159\u00ed a minim\u00e1ln\u00ed ricassos (ploch\u00e1, nezkosen\u00e1 \u010d\u00e1st \u010depele v bl\u00edzkosti spoje rukojeti) lze snadno dos\u00e1hnout pomoc\u00ed LinerLock, Compression Lock nebo jin\u00fdch mechanism\u016f, kter\u00e9 nejsou um\u00edst\u011bny v rovin\u011b \u010depele; nicm\u00e9n\u011b s lockbacky jsou n\u00e1ro\u010dn\u00e9. Sal tento probl\u00e9m vy\u0159e\u0161il pou\u017eit\u00edm filozofie designu \u201edop\u0159edu rukojeti\u201c, kter\u00e1 roz\u0161i\u0159uje spodn\u00ed \u010d\u00e1st rukojeti sm\u011brem k pat\u011b okraje. Toto brilantn\u00ed \u0159e\u0161en\u00ed umo\u017e\u0148uje, aby se \u0159ezn\u00e1 hrana roz\u0161\u00ed\u0159ila t\u00e9m\u011b\u0159 po cel\u00e9 d\u00e9lce \u010depele a um\u00edstila ruku u\u017eivatele d\u00e1le dop\u0159edu pro optim\u00e1ln\u00ed kontrolu a p\u00e1kov\u00fd efekt. funk\u010dn\u011b, poskytuje stejnou schopnost „udusit se“ ve va\u0161em \u00fachopu jako choil ukazov\u00e1\u010dku, ale bez ob\u011btov\u00e1n\u00ed jak\u00e9koli pou\u017eiteln\u00e9 d\u00e9lky hrany. T\u00edm, \u017ee minimalizuje mrtv\u00fd prostor mezi p\u0159edn\u00ed \u010d\u00e1st\u00ed rukojeti a patou hrany, design RockJumper tak\u00e9 v\u00fdrazn\u011b sni\u017euje mo\u017enost zachycen\u00ed – zejm\u00e9na p\u0159i \u0159ez\u00e1n\u00ed lan nebo popruh\u016f ve vysoce nam\u00e1han\u00fdch situac\u00edch.<\/p>\n

Sal trval na lockback mechanismu pro RockJumper z n\u011bkolika d\u016fvod\u016f. Za prv\u00e9, dopl\u0148uje ostatn\u00ed vlastnosti no\u017ee, aby byl jeho design zcela symetrick\u00fd a jeho chod 100% oboustrann\u00fd. Lockbacks proveden\u00e9 ve stylu Spyderco tak\u00e9 p\u0159edstavuj\u00ed ploch\u00e9 „kopy“ (oblast na okrajov\u00e9 stran\u011b ricasso), kter\u00e9 „sklo\u0148uj\u00ed“ \u00fapln\u011b proti ty\u010di z\u00e1mku. Tato jedine\u010dn\u00e1 vlastnost znemo\u017e\u0148uje otupen\u00ed ost\u0159\u00ed \u010depele p\u0159i kontaktu s vnit\u0159kem rukojeti a v\u017edy byla ur\u010duj\u00edc\u00edm \u2013 ale nedocen\u011bn\u00fdm \u2013 rysem z\u00e1mk\u016f Spyderco.<\/p>\n

Uzamykac\u00ed mechanismus tak\u00e9 nab\u00edz\u00ed p\u016fsobivou pevnost a, co\u017e je velmi d\u016fle\u017eit\u00e9, silnou funkci samozav\u00edr\u00e1n\u00ed. Ve srovn\u00e1n\u00ed s jin\u00fdmi mechanismy, kter\u00e9 nejsou um\u00edst\u011bny v jedn\u00e9 linii s \u010depel\u00ed, lockback \u010depel autoritativn\u011b zaklapne a dr\u017e\u00ed ji tam i p\u0159i n\u00e1ro\u010dn\u00fdch \u010dinnostech, jako je lezen\u00ed.<\/p>\n

Stejn\u011b jako v\u0161echny z\u00e1mky Spyderco je mechanismus na RockJumper p\u0159esn\u011bji kategorizov\u00e1n jako st\u0159edn\u00ed z\u00e1mek. Tento styl z\u00e1mku um\u00eds\u0165uje uvoln\u011bn\u00ed z\u00e1mku do st\u0159edu rukojeti pro snadn\u00e9 zav\u00edr\u00e1n\u00ed \u010depele jednou rukou \u2013 zvl\u00e1\u0161t\u011b kdy\u017e je ukazov\u00e1\u010dek um\u00edst\u011bn na p\u0159edn\u00ed \u010d\u00e1sti rukojeti a pou\u017e\u00edv\u00e1n jako zar\u00e1\u017eka. Varianta tradi\u010dn\u00edho full-length lockback, st\u0159edn\u00ed-lockback, byl pr\u016fkopn\u00edky Harvey McBurnette, Dick Dorough a WT Fuller, kte\u0159\u00ed spolupracovali v tov\u00e1rn\u011b na pneumatiky v Alabam\u011b na konci 60. let. Pot\u00e9, co Fuller p\u0159i pr\u016fmyslov\u00e9 nehod\u011b tragicky p\u0159i\u0161el o jednu ruku, v\u0161ichni t\u0159i mu\u017ei \u2013 v\u0161ichni strojn\u00edci a za\u010d\u00ednaj\u00edc\u00ed no\u017e\u00ed\u0159i \u2013 spolupracovali na n\u00e1vrhu zav\u00edrac\u00edho no\u017ee pro Fullera, kter\u00fd by se dal snadno otev\u0159\u00edt a zav\u0159\u00edt jednou rukou. V\u00fdsledkem bylo to, co p\u016fvodn\u011b naz\u00fdvali slo\u017eka \u201efront lock\u201c. Zkr\u00e1cen\u00edm z\u00e1mkov\u00e9 ty\u010de tradi\u010dn\u00edho lockback mechanismu a \u00fapravou jeho pru\u017einov\u00e9ho nap\u011bt\u00ed vytvo\u0159ili t\u0159i mu\u017ei vzor skl\u00e1dac\u00edho no\u017ee, kter\u00fd umo\u017e\u0148oval snadn\u00e9 uvoln\u011bn\u00ed z\u00e1mku pouze jednou rukou.
