The Reddit community broadly regards Miyabi as a premium Japanese knife brand capable of lasting a lifetime with proper care, placing it among the top tier of kitchen knives alongside Shun and Wusthof. Users consistently praise the edge retention and craftsmanship, though they are equally consistent in warning that the hard steel requires careful handling and specialized sharpening. A small number of dissenting voices raise concerns about recent quality control declines and the knives' brittleness under rough use.
Miyabi knives can genuinely last a lifetime and are among the sharpest and best-performing kitchen knives available, but only for cooks willing to learn proper whetstone sharpening and handle them with care — the brittle hard steel is unforgiving of abuse or accidents.
Miyabi knives are praised for exceptional sharpness, outstanding edge retention, and beautiful aesthetics, with many users reporting years or even decades of reliable daily use. They are frequently cited as a benchmark Japanese knife for serious home cooks.
The most consistent criticism is that Miyabi's hard steel is brittle and prone to chipping if dropped or used carelessly, requiring a learning curve for proper sharpening on a whetstone. A few users also flag potential quality decline in recent years due to outsourced manufacturing.
One user with a birchwood-handle Miyabi noted it performs beautifully but admitted to being afraid to sharpen it, warning that the brittleness compared to European knives demands real care — they've never chipped theirs, but only because of disciplined handling.
A professional knife sharpener observed that once Japanese knives from well-known brands began being outsourced, quality and quality control dropped noticeably, echoing concerns that Miyabi's best days may have been over a decade ago.
A user who has cooked with their Miyabi chef's knife daily for nearly 10 years said it still looks brand new, attributing its longevity entirely to handwashing, drying, and storing it immediately after every use.
One commenter who owned a Miyabi alongside a $26 budget knife concluded the expensive knife eventually shattered during hard use, leading them to prefer a cheaper, tougher alternative — a minority view but a pointed one about the limits of brittle high-hardness steel.
