Stitchawl, I know a dozen licensed meat cutters who make a living using their knives that would agree with you . O' John Juranitch in his book as well . DM
I don't know where I picked up the habit, but somewhere along the line I was taught to "trust... but verify." Ever since then, when I read something or hear something, even if it comes from the most reliable sources, I try it myself before I believe/espouse/use/recommend, etc. For every scientific 'proof' there is another, just as scientific, disagreeing with it. I never cared about a string of fancy letters after a person's name. (I've got a bunch of 'em after my name so I KNOW they don't really mean squat!

) I try things myself. If they work for me I continue to use them. If they don't, they get shoved to the back of the closet. And note that I said 'work for
ME.' Probably many of these that don't work for me might work just fine for other folks.
As for the idea of steeling a knife... I've used top brands of all different sorts of steels; striated, smooth, round, oval, diamond covered, ceramic, glass, etc. I found that for
ME, a smooth steel works best. I found that for
ME, there is no difference between using a smooth steel rod or a smooth glass rod. I found that for
ME, daily use before I begin prepping dinner gives me the best results. I chose a
glass rod over a steel rod just because I like the idea!

Of course, these are just my opinions.
You know what they say about 'opinions!'
