Unknown crank tool to open this crank

[nmark]

I am a newbie, I wonder what tool can i use to open it? (knocking using a screwdriver might work, but that is bruteforce)

I wonder it can use the 2 round pin spanner?

 

[nmark]

this one?

The pin spanner will work. If you haven't got one already, I'd use a screwdriver.

2 screwdrivers crossed over will give you something to rotate by hand.

Screwdriver on one slot, and a mallet.
