They fix the angle for you, and that is the whole trade · review
A guided system with a genuinely adjustable angle from 10° to 35°, four diamond plates and a whetstone — the only sharpener here that can match a Japanese 15° edge.
What we would actually buy The only sharpener here that respects the angle a knife was ground at. For hard Japanese blades that is not a luxury.
A guided sharpening system adjustable from 10° to 35°, with four monocrystalline diamond plates at 220, 325, 600 and 1000 grit, plus a whetstone — seven pieces in total.
The reason this exists. Every pull-through in this hub is fixed near a Western angle, and using one on a 15° Japanese blade destroys the edge it was bought for. This matches whatever the maker ground.
The angle is set by the distance between blade and abrasive rather than by a clamp position, which the maker states gives fine adjustment. The result is repeatable in a way freehand is not.
It is a session, not a moment. Setting up, working through four grits and finishing on the stone takes time — and it produces an edge the pull-throughs in this hub cannot.
On sale at around $180 on the American Amazon store at the time of checking.

Because a fixed 20° device reprofiles a 15° Japanese blade, removing the thin edge it was bought for. An adjustable system matches whatever the maker ground.
No. It is more repeatable. Freehand is quicker once learned; a guided system gives the same result every time from the first attempt.

Someone with Japanese knives who wants repeatable results without freehand practice.
