Hey Ian--I kinda knew they were...
I personally enjoy Karl's work, infill or not. I have owned two infills. I love the weight, I love the feel and, of course, I love the results of one well tuned.
Karl's fit and finish is second to none--and that's aside from the meticulous attention to detail of all the components. One would be a joy to use.
The Gathering [sort of sounds like a horror film <g>] would be a treat. But sorry, even Holteys being present wouldn't hold a candle just to the fun of meeting everyone!
Take care, back to filing saws...
Mike
