Does anyone know what the "protective EDP (Electric Discharge Plating) coating" used by Cold Steel, such as on the aluminium ti-lites is, and is it food safe/non-toxic?
I generally only leave DLC on food knives (both due to the fact that its considered non-toxic & i haven't found an easy practical way to remove it).
Should this (EDP) be taken off & how?
Thank you
 
You stick your fingers in or near your mouth. ☠️ That should be a genuine worry. You do that many times a day. Find something else to worry about. 🤪 Have a better day!!!

How often are you preparing food with a cold steel knife? Is it every day? Then buy a real food prep knife. Is it once a month? You are probably fine.

Its a great main food prep knife.
I compared it to a standard general knife in the kitchen, and interestingly it shares nearly the exact same proportions.
Family members also confirmed its Kitchen advantages.
If it didn't do such an all around great job preparing food-together with the great steel properties, i wouldn't have bothered making this thread to try and find the answer.
If i'm not mistaken, sometimes Knife companies are fond of (re)labelling their materials & processes with innovative catchy names.
The question is, does anyone know what this EDP-Electric Discharge Plating actually is and its food safety?
After browsing the Cold Steel forums, i got the impression that trying to contact the company isn't the way to go.

I mean it's right there in the name, I wouldn't put anything that has a discharge close to my food too often. Unless you're into that sort of thing. No judgement from us (except the silent kind)

From a little light layman internet reading, it seems to be a process that uses electrical discharge to layer one metal upon another. Often for decorative or corrosion resistance purposes.
The question seems to be what metal is overlaid and is it toxic? Tried to call them, no-one answered, i had the pleasure of hearing advertisements for outdoor gear till i gave up & hung-up.
 
from the website - "and CNC milled 7075 Aluminum handles which are finished with a protective EDP (Electric Discharge Plating) coating."

it reads to me that the handle is EDP coated - not the blade, I woudnt worry about it

Thank You!
Rereading it, i see that the earlier part also implies this:
"They feature sharp and strong bead-blasted CPM-S35VN Alloy blades, and CNC milled 7075 Aluminum handles which are finished with a protective EDP (Electric Discharge Plating) coating."
It states that the blade is bead-blasted and the handle is EDPed.
Thanks alot for the clarification!
