Looking for a tool. 8mm hex with 15mm flats, for stubborn crank bolts -FOUND! (self.bikewrench)

This is to help get off crank bolts. I swear I've seen it around but I can't find who makes it right now. It's a 8mm hex/allen (kinda stubby), and it has 15mm flats just outside that so you can put something like a pedal wrench on it. Might be kind of skinny flats.

I thought this might have been made by pedros, but I don't see it on their site. I assume this would be steel construction by whoever makes it.

My use case is that I have a medium size portable tool bag, and the regular 8mm hex is fine, except when it isn't. And i dont carry ratchets, let alone a big one. But I carry a beefy pedal wrench, so the 15mm flats would be perfect for this. Any leads?

Edit: I found it! EVT makes it. https://www.efficientvelo.com/tools/knuckle-saver-pedal-wrench-adapter

I think it worked, I trust that guy more than some clean hands. He's busted a knuckle before

I can't find an off the shelf tool for that. Pedro's universal crank puller has an 8mm built in and the handle is removable leaving a larger hex for a wrench. Not sure if that is a 15mm hex head though.

The Park Tool CCW-5 might work too. The 8mm allen/14mm socket part can be somewhat easily knocked out of the handle and carried alone. I can't remember what size the remaining big hex is.

Run over to your LBS and measure up either of those.

Thank you for the ideas! I wanted something slightly more purpose built, but your head's in the right place
