While there already was a thread for this tool, i didn't personally own the thread so, i just felt like making another one.
This is a remake of an already existing tool, which it seems the owner has decided to go AFK, for whatever reason.
So i decided to remake the tool, going by just the screenshot that the guy had, and this is what i came up with.http://omgglikeitspsyk.info/jackknife/
It takes Limited / Full API (full showing you more.)
I currently use this to check people who want to join, you can see their mails and skill so you can tell if they may be an active PVPER or not.
The original thread for this tool is here : http://www.eveonline.com/ingameboard.asp?a=topic&threadID=1325909
