For years, I have never been able to get a sharp edge using a whetstone.

Especially with Swiss army knives.

Can someone help me?

Thanks,

Stainless steel just does not take a sharp edge. If it does when
sharpened, it loses the edge quickly.

Rather than a whetstone, I use a sharpening tool. It won't do much for
stainless steel, but wears the blade more evenly than a whetstone.
There are a variety of tools available at your local hardware store.
