Specialized spanner.
Strike the Wave pliers.It takes a standard sight adjustment 4-point bit. Perfect fit and not proprietary.(Image removed from quote.)
That looks like what I need! Now to find somebody that sells it. It also looks like Gerber makes a military variant of the MP600 multitool that has this implement on it. I have several MP600's, but not that one. I may be able to get the sight tool and add a multitool to my collection at the same time! .
This knife is a bit of a disappointment. I loosened the pivot a little bit, heard a bit of a snap, and now the blade does not flip open automatically unless I flick it a little bit with my wrist . There is still a spring in the blade, it is just not as strong. Something inside of the thing must have disconnected. I will be returning it tomorrow.
Why did I loosen the pivot? I was trying to tweak it to make it open a bit easier with my thumb. I now see that was not a great idea! I was also trying to center the blade a bit, which actually worked. It actually still opens by itself, the spring action is just not as strong. I was going to hang on to it because for a little while, I thought I may have inadvertantly improved it. However, the scales where the pivot screw is seem to have separated a bit from the lining, and even tightening the screw back does not fix it. I am going to exchange it for another one and give it another shot. To be honest, I could actually do without the assisted opening, but I like the knifes design.
Fair enough and apologies for my cheeky post. We've all been there.
