Victorinox Fibrox Santoku Knife Granton Blade 7 in (5.2523.17): problems, parts and running costs

Checked: 2026-10-19

Summary

The 5.2523.17 is a Swiss-made stamped santoku whose recurring problem is the edge: the one independent test that bought this exact unit found it “a bit dull from the beginning”, and a store review for the same SKU reports blunting within a week, so plan on honing and sharpening supplies. The handle also splits opinion — testers and owners describe a narrow neck near the blade that blocks a pinch grip. There are no consumables, no batteries and no subscriptions; the only running cost is sharpening gear, and the lifetime warranty covers defects but not wear. It is a good buy at or below about $58 from US knife retailers; at $68 and above forged alternatives are the better money.

Common problems and fixes

Surface rust and staining — Victorinox warns that citrus, onions and tomatoes left on the blade can discolour or pit it, and that air-drying leaves water spots that lead to rust; a r/victorinox thread on blotchy used blades was answered as surface rust. Fix: wash promptly after use and dry immediately with a towel, wiping spine-to-edge; never air-dry. [5][18]
Dishwasher wear — the product page says dishwasher safe, but Victorinox’s own care pages recommend hand washing all large knives and Knivesandtools’ spec sheet says “yes but we strongly advise against it”; owner forums split on daily dishwasher use. Fix: hand wash with mild soap and dry the blade right away. [1][4][16][19]
Stamped blade holds an edge less long than forged — Victorinox’s buying guide says a forged blade contains more carbon and stays sharper longer; one owner complains the stamped sheet blade “doesn’t keep an edge”. Fix: accept the 4.2 oz weight tradeoff, or move up to a forged santoku when edge retention matters more than weight. [30][33]

Parts and consumables

No user-serviceable parts, no spare-parts channel, no consumables, no batteries and no subscriptions; knives are serviced under the lifetime warranty, not repaired by the owner. [3][16]

Yearly running cost

Not enough data. There are no consumables, no batteries and no subscriptions. The lifetime warranty covers material and manufacturing defects only, not wear, cosmetic damage or misuse. [16][3]

When it is a good buy

Store prices observed 2026-10: Victorinox US direct $66.00 excluding tax [1]; Williams Food Equipment $51.99 sale [11]; Chefs’ Toys $57.49 web price (MAP $62.00) [14]; Knife Merchant $62.00 [10]; Cutlery and More $65.99 for the same blade/handle family [12]; Big Erics $67.99 [15]; WebstaurantStore $62.00 for the 5.2523.17B variant [34].

At or below about $52-58: strong value — a Swiss-made, NSF-certified 17 cm santoku with published factory geometry and a lifetime warranty, undercutting the manufacturer’s direct price by 20% or more. [11][14]
At $68 and above: weak value — compare forged santokus, because the stamped edge-retention limit becomes the deciding factor at that level. [15][30]

Named alternatives: the MAC Superior, ATK’s Best Buy santoku, is the better choice when you want the top budget performer ATK tested [6]; Tojiro at about $40 is the better choice when steel and grind quality matter more, per a r/chefknives comparison [23]; Victorinox’s own straight-edge santoku is the better choice for heavy users who sharpen often, per the manufacturer’s buying guide [30]; the Swiss Classic 6.8523.17B at $62.00 is the same 6.7 in fluted blade with a different handle when the Fibrox grip does not suit you.
