  1. @Purr Cat If they were $$$, and you intend to use them for years-and-years, be very mindful of sharpening them. Not even the highest-$$$$ knife will retain and edge and perform well if they’re sharpened improperly.

  2. After watching this, I really feel like the sharpest bulb in the class.

  3. Would you consider testing WiFi extender systems? Ease of setup and management, raw signal range over open air, amount of speed lost over distance, ability to carry through typical home construction, and amount of speed loss caused by those obstructions.

  4. Question for the keen minds (heh) in PF-land: how can one tell if a mid-quality chef’s knife that has been used and resharpened routinely has reached a point of no return, and should be replaced? Is there an easy no-tools test like “sharpen as normal, slice ten tomatoes, and see if the tenth is noticeably harder?”

  5. @Scott Larson I think PF chose these because the majority of people who actually try to sharpen their own knives will be looking for devices like these, rather than something that cost 2-3X more and which requires considerable practice to use effectively. So, testing what he tested gives him the greatest appeal to the most viewers. The viewers who sharpen knives routinely because their work in field, shop, or kitchen depends on a keen edge, already know which device is best. Unfortunately, as the microscope close up showed, these devices not only don’t restore a factory edge, some don’t even get close, and I think some removed so much metal that the material they’re now sharpening is incapable of holding an edge. They may improve a knife that registered in high-100s to low-100s, but after even a few days of kitchen use they’ll be back up to the point where they’re not just frustrating to use, but dangerous. And while the knives tested aren’t of the highest quality (my opinion is that if it comes in a bubble-pack hung on a steel hook, it’s probably not worth the work trying to resharpen), measuring the trend from initial sharpness, to extremely misused, and then after sharpening with a given device, still indicates what effect the device had.
