Those are nothing compared to some of the newer cage pedals. I remember when I got me new bike I accidently shifted the wrong way, foot slipped and planted in the ground. The pedal raked the back of my leg and stopped the bike. The skin hanging off the pedal looked like cheese hanging from a cheese grater.
I had some diamondback triple traps back when first statred riding freestyle and did dirt jumping. They destroyed my legs. I got Primo meat tenderize pedals. First set I didn't break in few months. The set I have now is 22 years old and been through 3 bikes. I wish I had swapped them on before my other pedals cheese grated the back of my leg.
