About Gyuto Club

Gyuto Club is an independent guide to Japanese chef knives and the whetstones and technique that keep them sharp. It is run by an enthusiast rather than a lab or a magazine, and it is published by Type 5 Marketing LLC, the company that owns and operates the site. We are not a retailer, we hold no inventory, and we are not affiliated with any knife maker. What we are is a place that treats a knife as a set of measurable facts and puts those facts where you can read them.

What we do

For every knife we cover, we compile the numbers the maker publishes and normalize them to one standard: the steel grade (VG10, VG-MAX, X50CrMoV15, and so on), the HRC hardness for that specific model, the blade length in millimeters, the weight in grams, and the edge geometry where it is stated. For whetstones we do the same with grit, abrasive, prep, base, and dimensions. Those figures come from manufacturer spec sheets and product listings, they are dated on each review card, and we rank our picks by a published method rather than a vibe. Prices are pulled live and dated, so a number you read is a number that was real recently — not a figure typed in once and left to rot.

Knives we claim to have tested: none

Everyone in this category says they tested twenty. We haven’t, and we say so. Gyuto Club owns no test lab and no rack of knives bought for the purpose of grinding through cardboard on camera. What we do instead is honest and, we’d argue, more useful: we compile the published specs, we do the geometry, and we cite the sources those specs came from so you can check our work. When a maker does not state a figure, we print “Not published” rather than inventing one. You can read exactly how that works on our methodology page.

What we are not

We are not a testing lab, and we do not own the units we write about. The author is not a bladesmith, a professional chef, or a metallurgist, and nothing here is professional, medical, or safety advice — sharpening and using knives carries real risk, and how you handle a blade is on you. We do not accept payment for coverage or ranking, and a commission never decides a pick. When the honest answer is “skip this one,” that is the answer you get.

Who writes this

Stephen is a knife enthusiast — genuinely into this — who reads spec sheets and steel data sheets for fun. He is not a bladesmith or a professional chef, and Gyuto Club owns no test lab. What he does bring is a habit of pulling the manufacturer numbers, normalizing them to one standard, doing the geometry, and saying so plainly when a knife doesn't hold up to its marketing.

Stephen V. is the founder & lead writer. The byline on our guides is a real person with a real point of view, not a faceless “editorial team,” because you deserve to know who is telling you what to buy.

Why this site exists

Most knife content tells you a blade is “razor sharp” and “premium” without ever naming the steel, the hardness, or the angle it’s ground to — the three things that actually decide how it cuts, how long it stays keen, and how easily you can bring it back. The incumbents hide those numbers because numbers invite scrutiny. We publish them because scrutiny is the point. If we ever get a spec wrong, tell us: our editorial policy commits us to fixing errors and noting that we did, our affiliate disclosure explains exactly how the site is funded, and you can reach us any time through the contact page or at info@gyutoclub.com.
