I understand, please bear in mind you created a fringe point to which very few or no one at all will ever have these specific pedals.

I've seen too many people use cone wrenches in an attempt to remove pedals to which they messed up their cheap tool and scarred pedals badly.

I am almost certain MKS themselves may have a specific tool for them as anything to do with a pedal on a crank requires a PROPER tool that is both hardened enough and sufficient length to provide necessary torque that a thin short and soft cone wrench can not provide, ever.

Again, NEVER use a cone wrench for pedals, period.
