I agree with you in principle. I have two Japanese knives that were ordered on-line. I am beyond happy with them. I was fortunate to get excellent advice from two of my brothers. They are both knife aficionados. One of them makes knives. They both have Japanese knives that I used before ordering mine. I had some criteria - I wanted a carbon blade with a stainless clad, a hexagonal handle, slightly blade heavy. I have nerve damage in my arm and hand. The slightly blade heavy knife allows the blade to do more of the work. They both have larger knives - close to 10". I did not want one that large. My chef knife is closer to 8".
I recently acquired a boning knife - shorter with a deeply curved blade and a very fine point. Another gem!
My knives are not technically razor edged although you could shave with them. A true razor edge is too delicate for the kitchen. When I visited Brother in Colorado he sharpened my knives. Because he makes knives he has professional quality sharpening equipment. He put a micro bevel on my knives. You are correct - either would cut you to the bone in the blink of an eye. A tool that demands a great deal of respect.
When I acquired my chef knife Brother made a horse butt strop for me. I treat it with 50,000 grit Diamond Paste. I use it every time I use my knife. For touch up sharpening I use a Spiderco sharpening tool. Once a year I send my knives to Brother for a professional sharpening.
A good, well maintained knife is a joy. A true thing of beauty.
My Niece's husband worked as a prep chef for Brennan's in Houston. He banned my Niece from touching his knives when he found that she had put them in the dishwasher.
