Koj xav tias rab riam zoo tshaj yuav tsum yog dab tsi? Ntse? Tab sis koj tsis tau twv! Qhov ntse ntawm rab riam tsis yog ib qho thiab nyob deb ntawm qhov tseem ceeb tshaj plaws, qhov txaus txaus …

Tom qab tag nrho, txawm tias rab riam npub tuaj yeem ua kom ntse dua. Qhov zais ntawm riam zoo meej nyob rau lwm qhov. Samura qhia 5 lub hauv paus ntsiab lus ntawm rab riam chav ua noj zoo meej.

1. Hniav geometry

Qhov zoo tshaj plaws SAMURA hniav muaj qhov nqes hav los ntawm lub taub hau nws tus kheej mus rau qhov txiav ntug. Nws yog cov Japanese nqes hav uas tso cai rau koj ua kom yooj yim ntawm kev txiav. Yav dhau los, txoj kab nqes hav ncaj ncaj yog hom nrov tshaj plaws ntawm cov hniav. Lawv tau los ntawm Japanese katanas, Viking Saxons, Roman gladius, Spanish Navajs, Scottish dirk, Mameluk ntaj, Indian tavlyar thiab Arab shamshir. Kev siv thev naus laus zis, nws tsis yooj yim kom ua rau qhov qis qis thiab tsis yog txhua qhov pheej yig. Riam nrog txoj kab ncaj tsis tuaj yeem pheej yig, yog tias tsuas yog vim qhov tseeb tias kwv yees li 60% ntawm cov khoom raug tshem tawm (pov tseg) thaum tsim cov hniav. Tab sis tsuas yog cov hniav tuaj yeem txiav txig.

2. Hniav tuab

Yog tias koj piv SAMURA hniav nrog rau lwm yam (siv tau) riam, koj yuav pom tias cov hniav Samura nyias nyias. Ib rab riam txiav zoo dua, riam, zoo li rab chais, siv zog hla txhua yam khoom. Ntawm tus kov, cov hniav muaj tuab li ntawm 3 hli thiab txaws tau yooj yim rau ntawm qhov taub mus rau qhov tuab ntawm 0.1 hli - qhov no ua rau cov hniav hloov tau yooj yim thiab ywj pheej.

3. Riam hnyav

Cov riam Samura yog qhov pom tau yooj yim dua li lawv cov neeg sib tw. Cov riam yuav tsum tsis hnyav - qhov no yog ib feem ntawm Samur lub tswv yim. Lub teeb riam - tus kws ua zaub mov txhais tes tsis nkees, rab riam tswj tau yooj yim dua.

4. Lub zog ntawm cov hlau yog qhov tseem ceeb

Tsuas yog cov hlau Nyuaj Nyuaj Nyuaj muaj peev xwm muab lub kirenagu siv tau ntev (muaj peev xwm ntawm rab riam kom ntse ntxiv, uas yog, rab riam yuav nyob ntev npaum li cas). Samura riam muaj qhov nruab nrab hardness ntawm 58-61 HRC, uas yog qhov zoo tshaj plaws rau riam riam. Tsawg zog hlau npub sai sai, cov hlau nyuab nyuab heev.

5. Ntsej muag

Samura riam yog ntse heev. Tes ua kom ntse ntawm cov pob zeb ntub thiab txhuam cov ntug txiav yog qhov nyuaj dua thiab kim dua li cov cuab yeej siv tau yooj yim ntawm lub tshuab, tab sis tsuas yog hom kev ntse no yuav ua rau koj xav tsis thoob ntawm kev txiav Japanese. Lub kaum ntse ntse ntawm kev txiav ntug sib raug rau tus qauv Nyij Pooj - 18-21 degrees.

Raws li koj tuaj yeem pom, rab riam zoo meej tsis yooj yim li nws zoo li. Tab sis kom nkag siab thiab hnov qhov txawv - koj yuav tsum sim nws tsawg kawg ib zaug.
