Yet another example of me doing things wrong for my whole life was recently brought to my attention. I have always stored my knives, those that go in the vertical slots, with the sharp edge on the bottom, not ever thinking as I slid the knives into place that I was dragging them against the wood. Guess what that does? Yep, dulls them. Duh! They are now sharp-side up. A few more tips are listed at the link below.
Big shout out to Deborah K. for this sharp tip!
