Umnumzaan Glass Break: SUCCESS

Haven't really seen a definitive video of people breaking tempered glass with the Umnumzaan. I've seen laminated and plate glass, but not tempered, which is used in automotive vehicles side and rear windows, along with larger panes of glass in commercial applications. 

The Umnumzaan, although complete with a steep price tag, is certainly a great all around Every Day Carry knife. As per the usual reviews, adding a CRK to your collection is never something to regret, and I highly recommend saving the money to purchase one. Similar to a Sebenza, the Umnumzaan is complete with titanium scales, a frame lock, and bronze washers, along with S30V steel (although newer models have been upgraded to S35V, a debate on its own regard). There are however, some differences. The Umnum (for short) is complemented by a glass breaker near the pivot, which this video should prove effective. The frame lock, retains a ceramic disc, allowing for smoother lockup, and a sturdy lock as well. There are more to list pertaining to this knife, but long story short:
