Dalmo Mariano from Brazil did try out quite some designs in his workshop before he arrived at creating his perfect professional throwing knife: the Faka. It is laser cut from thick steel, then the bevels are added by hand. The steel used is a good Brazilian medium carbon steel, strong and reliable. It is tempered to a hardness in the low 40s of the Rockwell scale, because a throwing knife should never break on high impact, but merely bend so that it can be repaired easily. But apart from a few scratches at the tip, two test throws against a concrete wall did not damage the Faka at all!
