I had some drama with my Micron a while back, with one of the parts being factory overtightened so it couldn't be removed. Was advised by Iwata to get their cleaning kit pliers, but I was very put off by the price (I already have alts for everything else in the kit, so I'd basically be paying ~$80 for just the pliers). I went looking for a cheaper substitute. Not just any old pliers will do: the grip geometry is a little important in this context to getting an all-around grip so it doesn't just strip either the part or the jaws. I ended up getting these: Igarashi IPS PH-165, and they worked great! Just thought I'd share for anyone else who's been eyeing the Iwata kit, but felt the price was too high.
