I have a ka-bar Combat knife but it’s blunt as hell. I tried sharpening it with a whetstone but it isn’t sharp enough. I can’t afford to buy any other sharpener. Can you please tell me the proper to sharpen it? I want it to be sharp as a razor.

i recently bought a cheap 0 japanese
440 stainless steel sword. I call it my "akai ryu" but problem is its super super dull.
it couldnt cut toilet paper.
can someone tell me a extremly good way to sharpen it? it doesnt have to be easy or fast, it would be better if it was. hell, even if someone knows where i can find a knife/sword sharpener at, that would be nice.
