Looks like a good tool you have there. I never used a hammer of the N series, but like my 3B very much.
I recommend Mark Krause's booklet as well as any other Nazel info you can get. Thought I had a spare copy of the booklet, but can't find it now.
Question:
Does anyone know of a 5B Nazel for sale..I guess a 5N would work as well after seeing this hammer and the videos by Grant on youtube.
I am casually looking.
