During my usual scan of the pegboard displays at LBS, I paused to look at blister packed cone wrenches (all were Pedro, I think). While the 13mm had more or less reasonable dimensions and price - roughly 7" handle; about $7 - the 15mm was comparatively huge and 2x-3x the price. Sure, more steel increases cost, but isn't 12" of leverage on a cone wrench massive overkill? I certainly would never buy such a beast, much less carry it on the bike.
Because I didn't like the large sizes of the cone wrenches I'd seen, I made one by grinding down the cheeks of a 13mm-15mm open-end wrench. It turned 26 years old this month.

I'd guess the 15mm was specifically made as a pedal wrench which would account for the larger size.

Pedal wrench .... That's possible, I suppose. But it's so thin; exactly like a cone wrench. I prefer thick jaws (more bearing surface) on wrenches that I lean on. I like my set of Pedro tire levers but the "pedal wrench", if that's what it is, seems ill-conceived.

There are quite a few pedals that demand a fairly thin wrench. (It's probably still thicker than a cone wrench, or else the cone wrenches are unusally thick.)

It might be a dual-purpose wrench for cones and pedals.

Many pedals don't allow a full-width 15mm wrench to decrease the q-factor.

"q-factor" Would that be "lateral bending stress"? Makes sense to me that one would want the distance between pedal and crank to be "vanishingly small" (as my calculus text put it).

That wasn't a cone wrench. It was a pedal wrench. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts.

Q-factor, as I understand it, is primarily considered a knee stress issue; the farther apart the pedals are, the greater the angle which the knees must deal with. -- Typoes are a feature, not a bug. Some gardening required to reply via email. Words processed in a facility that contains nuts.

It depends on each rider's anatomy. For any given rider, having the pedals farther apart may match their knees' natural tendency (or is that tendoncy? :-) better, and vice versa.

Which is why I find "KneeSavers" (pedal axle extenders to increase Q-factor) to be a poorly-named product. They probably saved the knees of the guy who invented them, but for most of the people out there, they'll do more harm than good.
