I really, really love this tool. I had to get it from Europe on one of my infrequent orders when I order stuff that you generally cannot get in the US. This is a Cyclus Chainring Tool. The little dies in the top of the picture fit in the right side of the tool and hold the back of the chainring nut, instead of one of those cheap little sheet metal tools that are all that you can get in the US. The one on the left marked "E" seems to fit everything that I have right now. The tool squeezes the the chainring bolt and you insert the Allen wrench through the left side of the wrench. You squeeze the tool in one hand and turn the Allen (I use a Park Y wrench) with the other. No slip, no fuss, no mangled tools or nuts. Never had it fail to work since I got it. I sometimes need to remove chainrings that have been in place several decades.  The only thing that it does not fit is the secret bolt on the backside of a Sugino or Clipper crank.

While very exotic, indeed, I'm almost incapacitated by flashbacks of my early dental experiences. Gaaah!

While I'm not immune to buying things that are over the top in a multitude of ways, I bought a Pedro's Chain checker plus II(as in 2) because I needed a better chain measuring device and it had a chainring nut wrench on one end. It fits those nuts very well, no slips, and it's much longer than the horrible Park thing so you can use some leverage.  I'm sure the Cyclus tool works even better but for a $100 I would rather spend money on something else as I'd rarely use it. If you have one of those knuckle scraping cranks from Sugino it would help there.

It sounds like you, Laing, use it more than I would so I can see it's value there. I was going to be buying some Cyclus tools from Europe myself, it's nice to have different manufacturers than the usual ones here.
