+1 for a long one. in 2016 I bought a vintage
Zeus pedal wrench (from 1970's - Made in Spain) off CL from a woman who used to own a bike shop. don't remember the price but it was cheap, $20 maybe? it's long & skinny. it has 2 diff. sized notches
15mm at one end & 14mm (aka 9/16) at the other end. seems to work on anything I come across. it might be nice if the handle was wider/thicker, where one's hand applies pressure. but not really necessary, cuz whenever I swap pedals, I clean & lube threads as necessary. so I think my hard battles are over
