I had studied Silat Cekak Hanafi before Sendeng, and was taught that the parang Lading, the official weapon was smithed according to specific measurements of the owner, thus making it a perfect combat companion. Any error on the smith's part could cause the weapon to 'makan tuan' or accidentally hurt its owner.
I had also studied Silat Melayu Keris Lok 9, which taught that a personal Keris needed to be 'serasi' (affinitive) to the owner, and similar physical measurements were required to avoid the weapon 'betraying' him.
Guro Omar Hakim also gave measurement rationale for Pekiti Tirsia Kali for the length of certain sticks and knives used, which determined the proper grip required.
My question to Haji Jamaludin was based on all of this experience. So, I asked the question of the sword in Sendeng:
"Cikgu, does the sword have a measurement?"
"Why do you need a measurement?" he asked.
"Well, so that the weapon will not 'makan tuan'," I answered confidently. What he said next made me feel the smallest I'd ever felt.
"Senjata makan tuan, maksudnya tuan tak reti guna senjata!"
(A weapon that hurts its owner means the owner isn't competent to wield the weapon!)
Sigh. To this day, I've yet to live it down.
