Tarzan's Knife ( Excerpts from
BladeForums.com )
After the death of his parents in the African jungle, Tarzan was able to compete for survival using his intellect and his father's hunting knife to compensate for his lack of physical strength.
What sort of belt knife would one expect in the early 1900's, as owned by an English Lord with military experience and big game hunting experience?
Well, we know that Lord Greystoke and his wife set sale from Dover for West Africa in 1888. At this time, Sheffield England was producing a number of bowie knives as they were in vogue at the time. Burroughs describes it as a "Hunting knife." By that discription we can only really rule out things like daggers and folding knives. I don't think it would have been skinning knife, or anything else so small. Soon after Tarzan finds it, he is confronted by the huge gorilla, Bolgani. In the ensuing struggle, the knife "sank deep into its body the gorilla shrieked in pain and rage." Burroughs also describes the knife in the same fight as having a "long, sharp blade." And yeah, Tarzan stabs to death the great bull gorilla. So I'm gonna guess this hunting knife is BIG.
in an issue of Blade magazine, the author thought a slim Bowie knife from a Sheffield maker would more than likely have been his knife. I believe he said from Wostenholm and Sons.
