Direct answer: BESS is a sharpness measurement scale — the Brubaker Edge Sharpness Scale — read in grams on an Edge On Up tester: the lower the number of grams of force needed to sever the test medium, the sharper the edge. It is not a knife brand, a steel, or a guarantee of quality. A BESS score tells you how sharp one edge was, at one spot, on one day. Used honestly, it turns "razor sharp" from a slogan into a number you can compare before and after sharpening.
That correction sits at the top of this guide on purpose. An earlier version of this article presented "Bess" as a knife maker with a century of heritage, its own alloy and a full knife range, wrapped in first-person stories about testing dozens of knives and repairing a grandfather's heirloom. That story could not be substantiated, and it is gone — all 28 fabricated first-person claims with it. What replaces it is more interesting and actually true: BESS is one of the few genuinely useful ideas in knife sharpness, a way to measure an edge instead of arguing about it. If you cook with Damascus kitchen knives — the range in the chef's best kitchen blades collection is the natural place to look — understanding BESS helps you judge sharpness claims, track your own sharpening, and know when an edge needs work. No scores are invented for any knife below. That restraint is the point.
What is BESS, exactly?
BESS — the Brubaker Edge Sharpness Scale — is a standardised way to put a number on sharpness, developed by Mike Brubaker and used with the Edge On Up testers sold for workshops, sharpening services and serious home sharpeners. The test is simple in concept: the edge is lowered onto a certified test medium under increasing, measured force, and the tester records the force, in grams, at which the medium is severed. Less force means the edge did the work more easily. Less force means sharper.
Why grams? Because sharpness, underneath all the poetry, is about pressure at the very edge — how thin and how even the apex is where the two bevels meet. A keener, cleaner apex concentrates the same push onto a smaller line of contact, so it parts material sooner. Measuring the severing force is a practical proxy for that geometry. It is not the only thing that matters about an edge — edge angle, polish, steel and the food in front of you all matter too — but it is measurable, repeatable and comparable, which is more than can be said for "shaving sharp", "scary sharp" and the other folklore units the knife world trades in.
The testers most people meet are the Edge On Up PT50 series, in a few variants aimed at industrial, professional and home use. The details differ; the principle does not. A certified test medium, a controlled push, a number in grams. If a sharpness claim anywhere does not involve a method like that — a defined medium, a defined force, a repeatable setup — it is a description, not a measurement. Descriptions are fine over dinner. Measurements are what you want before you pay for sharpening, or before you believe a listing.
What does a BESS score mean?
A BESS score means, approximately: the lower the grams, the sharper the edge at the point tested. As a general reference — the scale's commonly published interpretive bands, not measurements of any knife in this store — readings under about 50 grams are in the realm of fresh razor and scalpel edges; roughly 50 to 100 grams is very sharp; 100 to 200 grams is a keen working edge; 200 to 300 grams is a serviceable edge that is starting to ask for attention; beyond roughly 300 to 400 grams, most cooks and users would call the blade dull, and readings climb from there. Treat those bands as orientation, not law.
Three honest caveats belong next to every BESS number you will ever see. First, the score is local: it measures the spot on the edge that touched the medium. An edge can be keen at the heel and tired at the tip, and a single reading hides that. Serious testers measure several points along the blade. Second, the score is momentary: it describes the edge on that day, before the cutting board, the dishwasher argument and the month of dinners that follow. Third, the score depends on the test itself — the certified medium, its batch, and the consistency of the push. That is why the system uses certified media at all. A BESS number quoted with no method, no medium and no tester model is just a number wearing a lab coat.
And one more caveat, the commercial one: sharpness is not the same as quality. A very thin, very sharp edge on the wrong steel for the job can chip, roll or dull in an afternoon. A slightly less spectacular edge on a well-made kitchen knife can outcook it for a year. Buy the knife first — steel, geometry, handle, balance — and use BESS to judge and maintain its edge. That ordering is the difference between a measurement and a gimmick.
How is a BESS test actually done?
A BESS test is done by placing the tester's certified medium across the instrument, zeroing the scale, and lowering the edge vertically onto the medium with a slow, steady push until it severs, at which point the tester records the peak force in grams. The edge is tested at several points along its length, the readings are noted, and the test is repeated after sharpening to confirm what the stones actually achieved.
The discipline is in the details, and the details explain why casual sharpness claims go wrong. The push has to be slow and straight; a sawing motion or a sideways lean changes the force and flatters the edge. The medium has to be the certified one, seated the same way each time, because swapping materials swaps the measurement. The blade has to be clean and dry, since oil, moisture and food residue all change how an edge bites. None of this is difficult. All of it is skippable — which is exactly how a dull-ish knife acquires a heroic score in a sales thread. When someone quotes you a BESS number, the fair questions are: which tester, which medium, how many points along the edge, and was it before or after real use? A tester who answers those plainly is worth trusting. A listing that cannot answer any of them is telling you something.
For a home cook, the full instrument may be more than the job needs, and that is fine. The concept still earns its keep without the hardware: sharpness is a measurable condition that rises and falls, not a personality trait a knife either has or lacks. The paper test, the tomato test and the thumbnail test in the sections below are the kitchen-table cousins of the BESS idea — cruder, free, and honest about what they are.
How can you judge sharpness without a tester?
You can judge sharpness without a tester with three simple checks, each of which answers a slightly different question. The paper test — drawing the edge through a held sheet of printer paper — shows whether the whole edge cuts cleanly or tears and snags at a dull spot. The tomato test — slicing a ripe tomato with the knife's own weight — shows whether the edge bites rather than skids on a slick skin. The fingernail test — resting the edge lightly on a thumbnail to feel for bite, never pressing — gives a quick read on keenness. None of them gives you grams. All of them tell the truth.
Run the paper test slowly along the full length of the blade, heel to tip, and listen as much as look. A keen edge whispers through with a clean, continuous sound. A nick, a roll or a dull section announces itself as a tear, a catch or a change in pitch, and it tells you where the damage lives — which is precisely the information a sharpener needs. The tomato test is stricter than it sounds: a ripe tomato's skin is smooth, taut and unforgiving, and an edge that starts the cut without squashing the fruit, using little more than the knife's weight and a gentle draw, is an edge in genuinely good order. If you have to saw, press or both, the edge is asking for the stones, whatever its last BESS number was.
What these tests cannot do is compare two knives across town, or prove that a sharpening service returned your blade keener than you sent it. That is the tester's job, and it is a real job — sharpening professionals use BESS readings exactly that way, as a receipt. For the rest of us, the honest division of labour is: kitchen tests for the weekly question "does this edge need work?", and measured testing for the rarer question "exactly how sharp is it, and can you prove it?"

How do you sharpen a Damascus knife and keep its edge?
You sharpen a Damascus knife on a whetstone, little and often, working the bevel at a consistent angle — coarse grit only for damage, medium grit for a genuinely dull edge, fine grit and a strop for the regular touch-up — and you keep the edge by hand-washing, drying promptly, and storing the blade on a magnetic strip, in a block or in a guard rather than loose in a drawer. Sharpness is maintained in minutes a week; it is rebuilt, painfully, after months of neglect.
The full technique — soaking the stone, angle control, alternating strokes, checking for a burr, finishing on the strop — is laid out step by step in how to sharpen a Damascus knife, and it is the right page to cook from, literally, the first few times. Two principles from it matter most for BESS-minded readers. First, sharpen to a condition, not to a schedule: use the paper test to decide, and stop when the edge cuts cleanly along its full length. Second, measure honestly if you measure at all: a before-and-after reading on the same tester, same medium, same points is a real comparison; anything looser is theatre.
Daily care does more for your average sharpness than any sharpening session, because edges die by a thousand small insults rather than one big one. Glass and stone boards are edge killers; wood and good composite boards are kind. The dishwasher is a small, hot war zone of jostling and detergent — hand-wash instead, dry straight away, and put the knife back in its place. Acidic foods left sitting on a carbon-leaning blade invite staining and worse; the full rust picture, including what early spotting looks like, is in can Damascus steel rust?. None of this takes talent. It takes a routine, and a routine is cheaper than a regrind.
What are the most common BESS misunderstandings?
The most common BESS misunderstandings are: treating BESS as a knife brand or a steel — it is neither; treating a lower score as proof of a better knife overall — it proves a sharper-tested edge, at one spot, on one day; comparing scores from different testers, media or methods as if they were one currency — they are not; and assuming a factory edge's score predicts the edge in six months — your boards, storage and sharpening decide that. Each misunderstanding sells something. The measurement itself sells nothing, which is why it is worth understanding properly.
Add one more, the subtlest: believing a single number can replace handling a knife. Balance, handle fit, blade height, weight — the things that decide whether a chef's knife disappears into your hand or fights you through every onion — do not appear in grams. Our best kitchen knives guide works through those choosing questions in full. BESS belongs in your thinking as the sharpness chapter of a longer book. Read it well, enjoy how clarifying a real measurement can be, and then go back to judging knives like a cook: in the hand, at the board, over time.
How should you read a BESS score someone else quotes you?
Read a quoted BESS score the way you would read any measurement offered by someone selling you something: gratefully, and then with four short questions. Which tester and which test medium produced it? How many points along the edge were measured — one flattering spot near the middle, or heel, middle and tip, reported separately? Was the edge fresh off the stones, or had it worked first? And is the number being used to describe that edge, or to imply something much bigger about the whole knife, the steel and the brand? A score that survives those questions is information. A score that wilts under them was decoration all along.
There is a practical home version of this discipline, and it costs nothing. Keep a note — on paper, in a phone, wherever you will actually keep it — of when you sharpened each kitchen knife, what you did, and how the paper test felt afterwards. That humble log is your personal BESS ledger: not grams, not certified, but honest, dated and comparable across your own knives over time. After a few months it tells you things no single measurement can — which knife in your block holds its working edge longest between touch-ups, which board in your kitchen is quietly eating edges, and whether your sharpening is genuinely improving or just feeling industrious. Sharpeners who test on instruments will recognise the habit instantly, because it is the same habit: write the number down, compare like with like, and let the record argue instead of the adjectives.
That is also the fairest way to use this guide's product cards. No score is printed beside the G10 chef knife or either set, because no edge was measured for this article — and the absence is deliberate, not a gap to be embarrassed about. When your knife arrives, run the paper and tomato tests, note the result and the date, and start your ledger from truth. If you later send the knife to a professional sharpener, ask for a measured before-and-after and file that too. In a year you will know more about your own edges than any roundup on the internet knows about any knife — because your data will be about your knives, your boards and your cooking, which is the only sharpness that ever actually mattered at your counter.
Frequently asked questions
Is BESS a knife brand?
No. BESS is a sharpness scale — the Brubaker Edge Sharpness Scale — used with Edge On Up testers to measure, in grams of force, how keen an edge is. It is not a brand, a maker, a steel or a knife style. Any article or listing that presents "Bess knives" as a maker's range with its own heritage should be read with that correction in mind; an earlier version of this very page made that mistake, and this rewrite exists to fix it.
What is a good BESS score for a kitchen knife?
As a general orientation from the scale's published reference bands, a kitchen knife testing somewhere in the 100 to 200 gram range has a keen working edge, and a freshly sharpened edge can test lower. Scores drift upward with use — that drift is normal and is exactly what the measurement is for. These bands are reference context only; no score is claimed here for any specific knife, because none was measured for this guide.
Do I need to buy a BESS tester?
Most home cooks do not. A tester earns its price for sharpening services, knife businesses and dedicated hobbyists who need provable, repeatable numbers. Everyone else gets the practical benefit from the free kitchen checks — paper, tomato, fingernail — used regularly and honestly. Knowing what BESS is still matters when you shop, because it lets you ask sellers and sharpeners the method questions that separate measurement from marketing.
Can a knife be too sharp?
An edge can be wrong for a job without being "too sharp" in the abstract. Extremely keen, thin edges are more delicate: they reward good boards and good technique and punish twisting, scraping sideways and frozen food. Match the edge to the work — a robust working edge for heavy daily prep, a finer edge for delicate slicing — and maintain it there. Sharpness is a setting, not a contest.
How often should I sharpen my Damascus kitchen knife?
When the tests say so, not when the calendar does. For a home cook using a knife daily on kind boards, that usually means a light touch-up on a fine stone or strop regularly and a fuller sharpen when the paper test starts tearing rather than slicing. Technique and grit guidance are in the sharpening guide linked in this post. If you use a professional sharpener, asking for a before-and-after BESS reading is a fair, increasingly normal request.
Does BESS testing damage the edge?
A properly run test severs a fine certified medium at the tested spot and does not meaningfully harm a working edge; it is a measurement, not a workout. It is also local — it tells you about the points tested. Test several points along the blade for a true picture, and treat any single-spot score, however impressive, as a partial answer.
The bottom line: measure the edge, judge the knife
BESS done honestly is a small, clarifying idea: sharpness can be measured in grams, compared before and after, and argued about a great deal less. Use it that way. Ask method questions when scores are quoted, refuse brand stories built on a measurement's name, and keep your own edges honest with the paper and tomato tests and a whetstone routine. Then choose the knife itself on steel, geometry and feel — starting with the G10 Handle Chef Knife at $34.99 if one blade is the need, or the sets above if your cooking has outgrown one blade.
