Although not officially tested, after farming for about 10 hours and observing how it works, the Blinkstrike proc occurs just as often as sword specialization. Utilizing this sword in the mainhand gives an effective 10% chance per swing to get an extra swing.
Like said above, Blinkstrike brings back the proc-from-proc effect of old sword specialization. It is possible to have multiple free swings from an initial opening swing.
