Mira covers the objects a kitchen keeps for years: forged blades, pans, boards and the small tools whose care instructions quietly decide how long they last. The working question is usually not what a maker claims a thing can cut, but what the same page asks the owner to do afterwards — hand wash, hone, store away from hard surfaces, and which of those jobs the warranty never covers.
Prices in these guides are the standing list price on the maker's own store in the country named, read on the date printed beside them. A figure the maker does not publish, from wattage to edge angle to a local delivery rule, stays a gap in the text rather than an estimate. Each guide is read again in a separate review pass before it goes live.
C$120 over the older Ace and a C$599 shelf price that excludes tax; the extra money pays for a system link that needs a Sonos product from the linking list on the same system to run at all.
The Canadian store prices the full-bolster Classic 8-inch at C$220 and its half-bolster sibling at C$220 too. Same 58 HRC forged steel, so the money chooses a shape, not a grade.
