Zikhonya amakhalanso ndi zisankho zapamwamba, zoumba zakunja, nkhonya, ndi zina zotero. Nkhonya zimagawidwa kukhala nkhonya za mtundu wa t, nkhonya zamtundu wapadera.nkhonya ndi chitsulo gawo anaika pa sitampu kufa ndi ntchito kukhudzana mwachindunji ndi zinthu kuti deform ndi kudula zakuthupi.
nkhonya zakufa nthawi zambiri zimagwiritsa ntchito chitsulo chothamanga kwambiri ndi chitsulo cha tungsten ngati zida, monga nkhonya zachitsulo zothamanga kwambiri ndi nkhonya zachitsulo cha tungsten, ndipo chitsulo chothamanga kwambiri ndizomwe zimagwiritsidwa ntchito kwambiri.Ambiri ntchito ndi CR12, CR12MOV, asp23, skd11, skd51, skd61, etc. Tungsten zitsulo zipangizo zambiri ntchito kukhomerera ndi kumeta ubweya akamwalira, amene amafuna apamwamba zofunika.
