In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 385.
Cut it by the measure of the length, half of it, the tip and the width. The pieces cut off are the ayas (the eight directions points). The Dhvaja (banner) aya may help defeat enemies.
Simple meaning: Measure and cut the blade by its parts. A Dhvaja count may help defeat enemies.
धूम्राये मरणं सिंहे जयः शुनि च रोगिता ।
Dhuma may risk life, Simha bring victory, Shva sickness, Vrisha wealth and the ass sorrow.
गजायेऽत्यंतसंप्रीतिध्वांक्षे वित्तविनाशनम् ।
Gaja brings love and the crow may bring loss of wealth. Measure a sword or dagger by your own finger-width.
मानांगुलेषु पर्यायामेकादशमितां त्यजेत् ।
Leave out each full count of eleven. The remaining fingers give the results in order.
