A hair transplantation instrument [10α/10β/10y] for making multiple slits/incisions comprises of plurality of platform with knife extensions [20/90/130/160]. Plurality of platform with knife extensions [130] are used alongwith plurality of carriers [240/260] incase of hair transplantation instrument [10a] and plurality of platform with knife extensions [90] are used alongwith plurality of spacers [360] incase of hair transplantation instrument [10β], to keep the preferable distance between two respective rows of slits/incisions. Alternatively, plurality of platform with knife extensions [20/90/130/160] can be used alone for making multiple slits/incisions without spacer [360], by keeping the thickness of the platforms more than the knife extensions [80] as shown in Fig.9[B]. A hair transplantation instrument [10y] is provided with plurality of gaps [470] at desired distance to accommodate the plurality of platform with knife extensions [20/90/160]. Either of platform with knife extensions [20/90] can be replaced by the platform with knife extensions [160].
