Quality that starts before the knife reaches your kitchen.
Cozzini Bros uses a structured AQL (Acceptable Quality Level) program to inspect, measure, and correct every set before it goes back on the truck. Sharp, safe, consistent tools are not an accident β they are the result of a repeatable, data-backed process.
What is AQL at Cozzini?
Simple idea: we measure quality, we do not guess.AQL stands for Acceptable Quality Level. At Cozzini, it is our structured quality program that defines how many knives we inspect, which checks we perform, and what happens when something does not meet our standard.
β’ catch issues before tools reach your kitchen
β’ correct problems immediately, not on the next visit
β’ track trends over time across sharpening centers, routes, and sets
Real results: December CATRA performance snapshot
Edge retention and consistency tracked across sharpening centers.We use objective performance testing (CATRA) as part of our quality intelligence. In December testing, overall Cozzini CER improved by 20% (266 to 321) over the last five months.
AQL in Action
December CATRA averages by sharpening center
| Sharpening Center | ICP | CER |
|---|---|---|
| Boardman | 55.99 | 400.90 |
| Cerritos | 67.41 | 396.55 |
| Elk Grove | 63.38 | 365.98 |
| Hopewell | 59.49 | 316.82 |
| Houston | 44.86 | 241.60 |
| Orlando | 58.55 | 347.61 |
| Pineville | 24.49 | 200.76 |
| Stockton | 40.85 | 270.06 |
| Tukwila | 53.07 | 348.04 |
| Cozzini (overall) | 52.01 | 320.92 |
Note: Second shift was tested in locations that have a second shift. Pineville scored lowest due to excess tilt.
The 10-Point AQL Inspection Protocol
We check every batch for these specific quality indicators.Wrong Type or Handle Color
We verify the physical knife against the inventory record (KIMS). Mismatches are flagged immediately.
Cleanliness
Knives must be free from residue, rust, or debris. If it is not sanitary, it does not pass inspection.
Broken Tip
We inspect for chipped, bent, or missing tips. A damaged tip compromises safety.
Bent Blade
Blades must be straight. Warped blades affect cutting accuracy and are rejected for correction.
Handle Abrasion
We check for rough spots or deep scratches caused by machine contact.
Blade Abrasion
Visible scuffs or scratches from the stone are flagged as defects.
Burn Marks
Discoloration indicates overheating during sharpening, which can weaken the edge.
Heel Delrin Test
The heel must grip the Delrin stick instantly; sliding indicates a dull area.
Middle Delrin Test
The center must βbite.β If it slides, the edge is not sharp enough for service.
Tip Delrin Test
If the tip slides instead of gripping, it is rejected and re-sharpened.
How we use AQL data to protect your operation
Quality checks turn into trends, and trends turn into action.AQL sampling levels
AQL tells us how many knives we must inspect to be confident in the overall quality. The higher the risk, the tighter the sampling.
What we track
Behind the scenes, our team monitors:
β’ % passing AQL on first inspection
β’ common defects (chips, roll, bend, tip damage, excess tilt, angle consistency)
β’ repeat patterns tied to routes, accounts, or shifts
β’ actions taken (e.g. angle correction, retraining)
fewer dull tools, fewer surprises, and a higher baseline of safety and performance on every visit.
we would rather catch and fix a problem before delivery than let your team discover it on the line.
What customers should know about AQL
How this program supports your team every week.Does AQL mean every knife is checked?
We use structured sampling plus extra pulls for anything that looks or feels off β constant eyes on quality.
What happens if you find a problem?
Knives are corrected or replaced before they go back into your set. Patterns trigger escalation and retraining.
How does this help my team?
Less frustration and fewer workarounds during service β safer cutting and smoother prep.
Can we get visibility into the data?
Multi-unit groups can request reporting and trend visibility. Ask your Cozzini contact about quality reporting.
