Yes, their Ringed Razel is closer to the size you're looking for, but unfortunately doesn't have those same serrations on the back side:

If the chisel tip wasn't required, something like the SOG Team Leader Survivor might work for you, or maybe one of the SOG Revolvers?

Edited to add:

Thinking about this a little more, as a back-up & possibly only tool I don't think you'd go wrong with something like Wenger's RangerGrip 78. I have an older version of this knife and I don't think you'd be doing bad if this was the only tool left in your toolbox.
