I finally have some time for knife making and one of the things I've been working on is making more hearth steel. I want to get enough for a tanto, which has been somewhat of a challenge because of a persistent problem with carbon distribution in the initial pucks, more on that later.   On the suggestion of J. Arthur Loose, I got a used HVAC blower (an Amatek Windjammer) to replace the shop vac I was using. Definitely a fan (), it's quiet and powerful and the setup wasn't too bad
