Yep Lee, that tool design has been a + for artifact hunters. I'm relatively new and dig with a free crude copy, till it breaks. Some old timers around here dug with hayhooks for decades but have recently been converted to Kemp wigglers.
Next time James comes down I'm gonna try to trade a point for a couple of his superior tools, just to have them on hand. Let's see, that 3 1/4" G10 Montell I dug this morning should be worth........
