Fluke Networks D-Impactor Tool - Reversing the Blade

I just received the Fluke Networks D-Impactor Tool that I had ordered a couple of weeks ago. It is a very SOLID tool that will no doubt withstand a lot of use and make 110 block terminations go a lot quicker. I was pleasantly surprised at how heavy this tool is.
Fluke Networks D-Impactor (Model Number 10059000)

The tool itself features a reversible blade. One side terminates and the other terminates and cuts.

My tool arrived with the non-cutting edge facing out and I wanted to reverse it.There were no instructions on how to do this so I have written up a simple step by step guide on how to do this.

Setting up a LAG between 2 Juniper EX2200 Switches

I have been setting up some new Juniper EX switches and needed to create a LAG.

Juniper KB10927 has a detailed step by step guide for accomplishing this. However, when I followed the steps, the LAG was created and verified as being up but I could not ping through to the other switch. I rechecked my configuration and verified that everything was correct but I still was having problems. The LAG was up, but no packets were being passed.

I realized that this was a simple case of overlooking something. The two switches were both initially set up with basic default vlan:

default {
    l3-interface vlan.0;
}

Here is the basic configuration that I have for setting up a LAG when no vlans (except the default) are configured. It is important to note that the highlighted section was necessary because of this.

root@EX1# show interfaces ae0
aggregated-ether-options {
    minimum-links 1;
    link-speed 1g;
    lacp {
        active;
    }
}
unit 0 {
    family ethernet-switching {
        port-mode trunk;
        native-vlan-id default;
    }
}
