Not the first time, and probably not the last time I ask questions about this tool... Anyway, I am trying to organize myself to do a video on the NRS. As near as I can tell, other than the multiple variations on profiles, are the differences in 'included' angles being less than or greater than 90 degrees. I am wondering if we need specific names for those variations, and what they could be... Acute for less than 90, and obtuse for more than 90 degrees? Any other suggestions? Do we even need different names??? The acute type seem to be used more on bowl/side grain turnings, and the more obtuse seem to be used more on end grain turnings...
