So I got a new razor today, but it is blunt as a kitchen knife!

So now I have been honing for about 1 hour, using mostly 4k, but also 600# sandpaper.. Wondering about getting a coarse grit hone, because this can take some time.. What would you recommend?

I took some pics, seller also suggested it is a carbon steel blade. But aren't they easy to hone?


Here is my new razor besides a well honed smaller one, can you see the difference?
