The quality of your videos (and especially your magnified 🔎 images ) is amazing 👏 I use the exact same Naniwa 3k and shapton 5k stones to bevel set . (Im not as involved with jnats ,each to their own .) Great video 😊.
Hi there, it's a personal choice, you don't have to finish with a JNAT but IMO they are delivering the best result. Otherwise, you have many finishing stones like coticule, La Lune, Black Shadow, and many synthetic ones (shapton 12k, 20k, etc...). When using a synthetic finishing stone, you'll need to use green chromium paste on a step at the end of the process.
