    Are you getting shocked from static electricity or from the grinder? Two different things.

    If it's static electricity, like from shuffling your feet on carpet, you can get an antistatic electricity strap, like used in electronics, and wear it on your ankle.

    If you are getting zapped from your grinder, that's a grounding issue of the grinder.

    Are you using a glass platen?

    Winter dry air, belts on a grinder humming away, and add in a glass platen & ZAP! Well you don't even need a glass platen to get zapped but it sure adds to the fun.

    I get shocked very little but it's still shocking (harhar) when it happens. What helps in my case is spraying myself down with static guard (which I do anyway in winter - I had static cling) and I use more water on the blade. Yeah I'm sure that the water thing sounds stupid to you but I can literally shock myself but flicking the excess water off of the blade before hitting the platen and then be OK if I leave it on and dunk more frequently. I have an advantage here though, I grind horizontally so I have a blade face holding water on it while I'm grinding. I'm sure you have it vertical like most knifemakers so the water will run off and this won;t help much but maybe more dunking might, I can't say. Maybe I'm just nuts?

    Also, AJ's suggestion above of using a static strap/mat should be a good approach to helping here as they do work. Just keep the cord out of the machine.

    Anyway, yeah static electricity when grinding knives in the winter is a pretty well documented problem. Good luck with this!

    I'm gonna run a copper ground wire from the grinder to the ground in the breaker box in the shop. You resist a lot better than a copper wire.

    I get shocked like you wouldn't believe in dry winter days. When I say shocked I mean dabing at door knobs because I know it's coming.
    The worst time was touching a metal door part when exiting a cloth seated car, actually knocked me into a prone position across the front seat!
    I discovered static dissipating shoes, problem solved.

    I always poke my car with my keys before I touch the handle in the winter.

    By any chance, are you using a pyroceram platen liner?

    I had my KMG on a steel table with no grounding. I have been shocked so bad it screws up my grinds. Pyroceram liner and steel are not friends. I now have it on a grounded aluminum table and no zaps.
