all-in-one chainwhip/lockring spanner?
 

Does anyone know where one can purchase a tool like the Tomity tool with a chainwhip on the opposing side of a lockring tool? It seems as though the Tomity tool is either out of production or very difficult to find. I know that there was a similar Dura Ace tool made but I can't find that one either.

Are they still available anywhere? Any current manufacturers producing these things?

I have one made by Shimano, TL SR-22. Got it 2 months ago at my LBS for about $30 I think.
It costs more on this web site so I would shop around. I got the 1 for 1/8" chain but works on 3/32 as well.

Business cycles sells the so called Makino "super tool"

supertool looks pretty terrible. can it securely latch onto a cog and is it long enough to provide the leverage for the job? looks like neither is true but 'd like to hear otherwise.

after reading further on that link, i see it only works for 14 or 15 tooth cogs. useless.

anyone know where to buy a real version of one of these for a reasonable price?

I think the main problem with the Supertool is that it can only fit a small range of cog sizes, no bigger than a 15 tooth. If you need a cog tool for your street bike, then you might very well have a 16-18 tooth cog, which the supertool wouldn't fit well. Oh... and it's $120!

euroasia makes one too, which may have a larger range. i think they stock the dura ace one as well. it shouldn't be hard to order from a shop, quit looking online.

I have this dura ace one.
Its chain whip, lock ring tool in one.
Its so so.

how do you like it?

The Shimano tool works great. Long sturdy handle, more than enough chain for a 16t so would be plenty for more teeth. Rubber on the handle for my supple hands.
I can whack it with a hammer to remove seized cogs. I haven't used anything else but it works for me.
