Hmm, when I brought my bike in to the shop to get the headset inspected and replaced, i coulda swore i saw him use some sort of hook shaped tool with a notch on the end to loosen something (lockring of some sort?)

Was also thinking of getting this: https://www.amazon.com/gp/product/B0...A2RNBXAVQ4OOHG
which should be helpful for pretty much everything, yes? Or is having a individual blue handled one of each more elegant?
