Re-Tread Your Slippery Pedals

Cycling in the rainy NW ,pedals without clips require Grip .  Heres a quick cheap (free) way 
to give new traction to your old slick and slippery pedals before you slide off and crunch 
your shin or 'you-know-what' =( .  It was just about to happen to me .

This could also be done with a hacksaw blade but a dremel is what I used .
It took all of 5 minutes .   This is my 1st ible so feel free to lay on the critiques .

gather your stuff :
-SAFETY GLASSES (&or face shield)
-SAFETY GLOVES
-pedal wrench (usually 15mm)
-pedals
-dremel & cutoff wheel or hacksaw blade 

I alternate the direction that i cut the grooves hoping for better foot traction . 
Every other spike cut alternates 90 degrees from the one next to it .
I also cut a few lines into the flat surfaces of the pedal for good measure 

clean off the metal shavings .
put em back on your cranks .
Go test with your usual bike shoes  .

.. Tested . The pedals have at least 75% more grip. 
I recommend giving it a try with some worn but working 
pedals . 

I'm gonna try and add grip to some worn plastic Odyssey 'Twisted'
pedals next . Stay tuned please.
