He didn’t have a weapon. Gemmel had spoken of glass knives, but had never given one to Kelsier. So, he snatched up a shard of broken glass from the floor, heedless of the cuts on his fingers. Pewter let him ignore pain as he jumped toward Shezler, going for his throat.
He  probably  shouldn’t  have  won.  Shezler  was  the  more  accomplished  and  practiced Allomancer — but it was obvious he was unaccustomed to fighting someone as strong as he was. He battered at Kelsier with the dueling cane. But with pewter Kelsier could ignore that as well, and instead he punched his shard of glass into the man’s neck — three times.
In  seconds  it  was  over.  Kelsier  stumbled  back,  aches  beginning  to  register.  Shezler  might  have  broken  some  of  his  bones  with  his  battering;  the  man  had  pewter too, after all. The nobleman lay in his own blood though, twitching. Pewter could save you from a lot of things, but not a slit throat.
