That said, I will agree that some of this ‘angels-dancing-on-a-pin’ stuff is pure b.s. and that the subtle differences in performance are noticeable to maybe a few dozen people in the world, but not to the rest of us. I think that linear grinds have a lot of merit, and perhaps there may be something to the reticulated patterns in dryer snow, but some of the diagonal structures make no sense to me at all. Given that all of the cleaning, scraping and brushing tools on the planet are linear devices, no one on or off skis has ever convinced me that those patterns are faster. I am paying more attention to some of the neat ‘imprint’ tools coming out, and given the opportunity I’ll give them a try. However, it is going to take a lot of convincing to get me to permanently cut a pair of skis in this fashion.
