I've had the Shu for seven months and have been able to maintain the edge with occasional stropping with coarse and fine compound on a double-sided leather strop. The effects of this can seen if looking at the blade closely but this hardly detracts from the knife as I bought it to use it.
I wish I could say I carry the Shu every day but I don't always carry a knife to begin with and dispersing usage among many knives is an occupational hazard of being a knife enthusiast. That said, I began buying modern knives looking for that one knife to use whenever a knife is needed and watch as frequent use leaves its wear over the years. It did not turn out that way.
The Shu was an usual choice for me based upon my presumed preferences. I preferred knives with more straight lines than curves and with features that are so organic that they almost disappear into the overall knife. So a knife with a curved handle was out of my figurative comfort zone only to realize how comfortable the Shu's handle is. The handle fits naturally into my hand without any hotspots and effortlessly provides a secure grip.
Another feature I was unsure of was the button lock as I preferred liner and frame locks. Once again experience triumphed over assumption as the blade is held securely open and closed.
The blade is also busier than I usually like with a mirror finished bevel, stonewashed flats, a fuller and hole, a swedge, jimping, thumb studs and relatively large engraving. While a blade looking busy is in itself subjective the function of these various features come together in such a way that the sum of the parts is greater than the whole. And, I no longer think the blade looks busy because i have always preferred function over fashion.
