How to use Rockwell Hardness Files for knife making 

Thank you. I just opened my set of hardness files (exactly like the ones you show here) and the instructions are in Japanese. Your video helped a lot.

I have been using AEB-L alot lately and send it out for HT. It comes back at 60-61 HRC It can go a bit higher with a Cryo treatment. Love your tutorials and have been trying some electro etching of blades

You are doing it backwards. Start with the hardest files 1st, then work your way down. That way the softer files will last longer.

Wow , you're really, really good at things you are making. Good luck and best regards

Big thanks to you sir 👍

Great demonstration. Don't think I've seen this anywhere else, at least not showing in detail

Another fine video Dan. I have been using a set of chain saw files to sharpen my bread knives or serrated pocket knives. I have no idea of the hardness level, but they bite right through the knife blades. I was surprised with the bread knives as they are Henkels and supposedly very good quality. The pocket knives are normally the two-buck varieties at Walmart. I don’t expect these to be top quality so mostly they stay in the bottom of a tackle box or various tool pouches for the vehicles. The chain saw files are in a pack of three or four at Walmart, so I wasn’t expecting much but when they cut into the steel of the supposedly good knives I was surprised. I wonder how to get them tested for a HRC.

Thanks for sharing. I just ordner a sett like that on ebay
