Raws li tus qauv kwv yees, qhov tseem ceeb tshaj plaws ntawm kev lag luam kev tuav pov hwm khau khau yog cov ntiv taw tuaj yeem tiv taus qhov cuam tshuam ntawm 20 kilograms ntawm cov khoom tawv los ntawm qhov siab ntsug ntawm 1 meter thiab nqus 200 joules ntawm lub zog kinetic. Feem ntau cov khau kev nyab xeeb niaj hnub tau ntxiv lwm yam kev nyab xeeb los tsim cov khoom sib txawv. Dab tsi peb yuav tham txog hnub no yog lub luag haujlwm ntawm kev tuav pov hwm kev ua haujlwm khau hauv kev lag luam sib txawv:
Kev siv chainsaw tiv thaiv yog hais txog qhov muaj peev xwm hnav cov khau tiv thaiv khau rau cov neeg uas muaj feem raug mob los ntawm kev siv cov saw saw rau ntawm daim tawv nqaij, pob taws, ko taw thiab ntiv taw. Cov qauv kev nyab xeeb hais tias cov neeg ua haujlwm yuav tsum xaiv cov khau khau uas tiv thaiv lawv cov kev xav tau, thiab yuav tsum tsis txhob xav tias cov khau tib yam yuav raug siv rau hauv cov haujlwm tshwj xeeb. Cov chaw ua haujlwm sib txawv yuav muaj kev pheej hmoo sib txawv.
Kev tuav pov hwm kev ua haujlwm khau siv nyob rau hauv cov chaw kuaj tshuaj txhais tau hais tias cov khau tiv thaiv tsim nyog yuav tsum tau hnav hauv qhov chaw kuaj tshuaj uas siv thiab khaws cia, thiab cov khau tiv thaiv yuav tsum tau muab khaws cia. Cov khau khiab, khau khiab thiab khau zoo sib xws tsis raug tso cai hnav hauv cov chaw sim no. Cov khau khau uas tsim nyog yuav tsum npog tag nrho ko taw thiab tiv thaiv tag nrho ko taw. Cov ntaub ntawv khau, nrog rau cov khau khiab thiab sab sauv, yuav tsum tau sib haum nrog lub chaw soj nstuam ib puag ncig, kev tuav cov khoom thiab kev ua haujlwm. Nyob ntawm seb muaj kev phom sij li cas hauv chav kuaj, yuav tsum muaj kev tiv thaiv ntxiv rau khau.
Thaum xaiv cov khau kev nyab xeeb, peb yuav tsum xav txog seb ob lub ntsiab lus hauv qab no puas tau ntsib:
Durable: Muaj kev tuav pov hwm kev ua haujlwm khau yog ua los ntawm cowhide lossis tawv nyuj. Cov ib leeg feem ntau yog nrum ncaj qha mus rau sab sauv, thiab cov nyhuv ua ke yog zoo meej, txo qis qhov tshwm sim ntawm cov dej hauv qab, dej seepage lossis plua plav. Lub cev muaj cov yam ntxwv ntawm durability, hnav tsis kam thiab puncture resistance. Yog li ntawd, txawm nyob rau hauv qhov chaw ua haujlwm nyuaj tshaj plaws, nws tuaj yeem ua lub luag haujlwm tiv thaiv kev nyab xeeb hauv lub sijhawm ntev heev.
Kev nplij siab thiab kev nyiam huv: Cov khau yooj yim muaj kev nyab xeeb tuaj yeem ua rau cov neeg ua haujlwm tsim khoom thiab tiv thaiv cov kab mob ntev ntawm ko taw lossis ob txhais ceg. Cov cim tseem ceeb tshaj plaws ntawm kev nplij siab kev ua tau zoo suav nrog cov khoom siv sab sauv yuav tsum ua tau raws li cov qauv dej tsis zoo thiab ua pa, cov khoom siv sab hauv yuav tsum yooj yim nqus hws, thiab tsis hnov tsw yooj yim rau dissipate tom qab tshem cov khau.
