Ugh, that "professional" sharpener story hits home. I was all about those gadgets for years, swore by my pull-through sharpener. Then I watched a guy at the West Side Market fix a knife with a chipped tip in like two minutes on a stone. The edge was way better than anything my gadget ever did. Totally changed how I see it now.

Over a grand for one window? Honestly, that's insane.

Actually @pauljones, more data can average out the noise. The random stuff gets less important the more you stack it up.
