This will only be of interest to knife makers I feel but I have become really into making Japanese blades. One of my favourite features is the Hamon. I have tried various techniques to create one, but no successfully, so I decided to get back to basics and try the technique described in Jim Hrisoulas's seminal book "The Complete Bladesmith".
For those who are interested, this video might be interesting.
Also, as ever on this forum, I am always very grateful for any advice and ways to improve what I am doing.
