I agree with the Chosera 1k, it's been my go to bevel setter for more than a year now. I have tried King 1k, 1k super stone, a bunch of Jnats in the low grits , but so far for me nothing is as good as the 1k Chosera.

I also got the 1k Norton and it is perfect for repairs, but I always reach for the chosera when a bevel set is needed.
