What size hex?

[Esav Benyamin]

My new Nemesis could bust through a door, but after playing with it a while I noticed the blade had some vertical play. So I tightened up the hex screw of the pivot and the microscopic play went away.

What bothered me was that a 7/32 hex was too big so I used the 3/32 which was too small, and I hate using a small driver. This is metric, right? What size?

OK, it works fine -- I picked up a set of metric hex today, and snugged it up. It seems like however hard I try to tighten it, just like a Sebenza, it won't lock up the blade.
