This is the top tier of edge work: a premium katana sharpening service carried out by a master, taking a functional blade to an extremely keen, refined edge. It is the choice of connoisseurs, dojo owners, and experienced practitioners who treat the edge as the soul of the sword and want nothing less than the best.
The service applies an advanced, hand-finished sharpening to a full-tang blade — the kind built to cut. Because the result is genuinely sharp, it is intended for owners with real katana experience who understand handling and care; this is an upgrade for a working sword, not a decorative display piece.
Add it when you order a sharpened, battle-ready katana to lift the standard edge to master level. For practitioners moving toward tatami cutting, it is the natural finishing touch on a serious blade.
