That EAI tool is pretty sweet.

Sunlite is one of pake's suppliers.... obviously you can sunlite's exact same version w/o pake's logo for cheaper on ebay or amazon.... and the combo tool comes with the 1/8 section of chain.

I have that Sunlite combo tool and would have to say that I dont recommend it. Only reason is that the lockring wrench nib is semi rounded, and isnt very good at grippng lockring notches and mine eventually stripped to where the tool couldnt grip well enough to a point I would trust.

Lockring and chain whip tools are definitely occasional use tools but they are also tools that if not quality cause unnecessary wailing and gnashing of teeth. I suggest what I have - Hozan lockring tool and Park SR-2 chain whip. I swapped out the chain portions with 1/8th but kept the pieces around if I ever need 3/32. It only takes a minute to change it around. Both I consider "best of breed" tools. They make life easier and are worth their asking prices.
