A hollow, not an edge — and what it cannot do
An ice skate blade is not sharpened to a point: it is ground with a hollow between two edges, and both edges bite. That single fact decides what this shelf can and cannot do. The hand tools here — 12 € to 25 €, diamond rods and ceramic V-blocks — maintain a hollow that already exists and remove the burrs and nicks a session leaves. They do not cut a new hollow, and a blade that has lost its profile needs a machine at a rink. Any listing implying otherwise is selling a stone as a workshop. The first thing to compare is the abrasive: a diamond rod cuts steel and is what deburrs a nick, a ceramic block polishes, and the sets that hold both do two jobs. The second is whether the tool adjusts to the blade width, because figure and hockey blades differ by a millimetre or two and a fixed slot only fits one of them — the corpus shows « breitenverstellbar » on most of the shelf and it is the word to look for. The third is the hollow radius the tool is cut for, where it is stated: a shallow hollow glides and slides, a deep one bites and tires the legs. Then the practical part — whether the thing fits in a bag and can be used at the rink between periods, which is most of why these exist. We compare type, radius, abrasive, adjustable width, blades per pass, material and weight.
Two-sided stone — grinding and deburring — with an adjustable width
The cheapest tool here, with a grinding face and a deburring face, and five empty bullet points.
Best for: A bag pocket, for the nick a rink’s door-track leaves in a blade
≈ £8 / €12
Rotating stone — coarse diamond rod and fine stone — with a cord and pouch
A two-grit rotating stone in a fish-shaped body, with a cord so it stays in the bag.

≈ €17
12.5 mm hollow, two diamond-coated rollers, 69 × 21 × 45 mm, 113 g
The only tool here that names a hollow radius — and one of two listings selling the identical product.

≈ €25
Three stones of 6.5 × 3 × 2.5 cm, three pouches, adjustable width
Three stones and three pouches in one box, with their dimensions published — the only listing here that gives them.

≈ €17
The same reference, text, dimensions, weight and prices as the SkinStar here
The same product as the SkinStar on this shelf, under a second brand name, at exactly the same four prices.

≈ €25
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.

The live figure beside a product went and asked the shop for it the moment this page opened; any amount written into the text has not moved since the sentence was drafted, and it is the first of the two that counts.
