I have a Knifeless Rebar for office days or when visiting the big city etc. And it's great for that.
Naturally some shopping is done then too and here it failed me at opening clam shell packaging.
I mean, in a sophisticated manner

At first I was thinking about adding a Wingman package opener. But I'd like to spare the space for a Small Bit Driver to add later on (I use it regularly on my Wave).
Then the Spirit X chisel thingy came to my mind and how I like it.
So here it goes. Initially I wanted to leave it like this, ground on one side only...

But the edge was too rough. No wonder being a two sided file the edge was more like a saw.
I had the Dremel packed away already so did the other side by hand with a diamond stone. I chose a more shallow angle there...

The profile looks like this now...

I'm happy with the result. It works great as package opener, and chisel too...


PS:
I did not want to give the can-opener an edge for this. From my experience sharp edges on the can-opener can lead to metal shavings when used as actual can-opener.
