The method
How we score.
No lab coats. No sponsors. No everything-gets-five-stars.
Every other review site slaps 4.7 stars on all ninety products and calls it a day. That is not a rating. That is wallpaper. Here is exactly how our number gets made, so you can trust it or argue with it — both are fine, both are the point.
What the number actually is
It's a verdict, not a measurement. A score out of 5 for how well a thing does the single job it exists to do, weighed against what it costs and the reputation of the grain doing the cutting. It is opinion. We are telling you it is opinion. That honesty is the difference between a review and a receipt.
What we actually look at
- The grain. Ceramic that fractures sharp versus aluminum oxide that just wears down versus the mystery grit in a bargain multipack. What's doing the cutting decides most of the score before anything else.
- How long it lasts. Cheap paper that dies on the third sheet isn't cheap. Cut speed is nothing without stamina, and stamina is where the premium stuff quietly earns its markup.
- Whether it does its one job. A 40-grit belt that finishes smooth is broken. A 3000-grit sheet that removes stock is broken. We score things for the stage they belong to, not the stages they don't.
- What it costs to get there. A budget disc and a Festool disc can both earn a good score, because we grade each against its own price and promise — not against a fantasy where everything costs the same.
- What the people who buy it by the case say. The auto-body finisher on his fourth box of Mirka Golds knows something the product page will never admit. We read those threads so you don't have to.
The rules we don't break
- Nothing hits 5.0. Perfect abrasive doesn't exist. A perfect score is a lie with good posture.
- No paid positions. Not one, not ever. The commission is the same whether we praise a thing or bury it.
- No fabricated scores. If we can't form an honest opinion on a product, it doesn't get a number. We'd rather leave it blank than farm you a fake star.
- Every claim stays checkable. Real grits, real materials, real form factors. The jokes are ours; the facts are not negotiable.
And no, there's no byline
You won't find a smiling headshot and a fake “Senior Abrasives Editor” title on these pages. The house has a voice, not a mascot. The opinion is the brand's, the brand stands behind it, and that's the only credential that matters when the question is whether a disc is worth your money.
The questions everyone asks
Do you actually sand things, or just read spec sheets?
Both, and we won't insult you by pretending it's a white-lab-coat operation. We are an opinionated buyer's guide, not a materials-testing house with a rack of calipers and a grant. We sand. We also read the grain specs, the manufacturer data, and ten years of forum arguments between people who buy this stuff by the case. The score is judgment built on all of that — stated out loud, so you can weigh it instead of swallowing it.
Why does nothing get a perfect 5.0?
Because perfect sandpaper has not been invented, and the day it is, we'll be too busy using it to write about it. A 5.0 is a sales word wearing a number. We top out lower on purpose so the scores mean something relative to each other.
Are the scores paid for?
No. Nobody has ever bought a position here and nobody ever will. We earn an Amazon commission when you buy through our links, at no extra cost to you — that is the whole business model, and it does not move a single decimal point. A brand we recommend and a brand we bury both pay us exactly the same: whatever Amazon does, if you click.
A cheap no-name disc scored lower than a Festool. Rigged?
Rigged would be pretending they're equal. A ten-cent disc and a German engineering flex are not the same object, and a score that says otherwise is lying to be nice. Cheap abrasive that shows up and does the ugly work still scores fine. It just doesn't score like the thing that costs six times as much and lasts eight.
Rough honesty. Smooth conscience. That's the whole method.
