I never used one like the Jantz but I just watched a youtube video and it has a different approach. The Jantz requires semi-freehand work and seems like it's just a bit easier than a table and free hand grinding. I did use and like the Travis jig (holds the blade and the jig swivels ) I thought it was near production way back then.
