Keep the same angle that you had.

I got the coin idea from Field And Stream Total Outdoorsman Manual.

Thanks for this. I'm never sure of the angle so using the coin is a great tip!

Interresting technique using a coin to get the right angle. Thanks for sharing!

Why is there no edit-button? I forgot to ask, do you repeat the process on the fine side, or will the coarse side do?

After you have done both sides of the blade on the coarse side of the stone, switch the stone around [over] and repeat. See Step #5. ;)
