I think there has been some tool movement, but I added my house and work key to mine. Been using it for at least a year now. Don't have a photo but might be able to dig one up.
Can you put a Squirt plier head in it? It's something I've always wondered, considering the S4 used what I thought were Micra shears.
Are there any micra disassembley thread/vid? Im curious to see what one of those tools looks like at the pivot side.
