Mekhoa ea Tlhahiso:
Ho theha taolo ea boleng ba phallo ea phallo: tšepe ea thepa e tala ka tlung ea polokelo (lekola boleng ba lik'hemik'hale) → Ho itšeha→ Ho futhumatsa(Teko ea mocheso oa sebōpi) → Phekolo ea mocheso ka mor'a ho qhekella(teko ea mocheso oa sebōpi) Hlakola sebōpi(tlhahlobo e se nang letho)→ Machining→ Tlhahlobo(UT ,MT,Visal diamention, hardness)→ QT→ Tlhahlobo(UT, thepa ea mochini, ho thatafala, boholo ba lijo-thollo)→ Qetella machining→ Tlhahlobo (tekanyo)→ Ho paka le ho Tšoaea(setempe sa tšepe, letšoao)→ Thomello ea polokelo
Molemo:
Lintho tse ntle tsa mochini,
Mamello e phahameng ea boemo bo holimo,
Laola mokhoa oa tlhahiso ka tieo,
Lisebelisoa tse tsoetseng pele tsa tlhahiso le lisebelisoa tsa tlhahlobo,
Botho bo botle ba tekheniki,
Hlahisa litekanyo tse fapaneng ho latela litlhoko tsa bareki,
Ela hloko tšireletso ea sephutheloana,
Tshebeletso e felletseng ya boleng.
Liindasteri tsa Likopo:
Lisebelisoa tsa tšepe, lisebelisoa tsa merafo, likepe tse lebōpong la leoatle, lisebelisoa tsa ho phahamisa, mechine ea kaho, tlhahiso ea matla, joalo-joalo.
