Thanks a lot. What about this one,
I know him himself.

AnonymousI know him himself.

That doesn't work.

By the way, you are using emphatic rather than reflexive pronouns.

Why is the sentence incorrect?

Is it correct to say, "I myself made the ice-cream"?

tenjing Is it correct to say, "I myself made the ice-cream"?

Yes. I consider that a fairly formal way to say it. Less formally I might say

I made the ice-cream myself.

You'll almost always hear it in the less formal way in ordinary everyday conversations.

She made those curtains herself.
The kids built that dog

Yes, it emphasizes it was you and not anyone else.

Thank you both. One more question here,
I made it myself last week. Or. I made it last week myself. Which one is correct?

The first is more natural, in my opinion. The second is not incorrect
