Topic briefings
Each topic below links to an in-depth reference page with stats and inline citations. Use them as background, then reach out for direct quotes.
Dull knife dangers & kitchen safety
Why dull knives send more cooks to the ER than sharp ones. NEISS data, force physics, and the specific injuries hand surgeons see.
Honing vs. sharpening
The distinction most home cooks get wrong. Rod type taxonomy, correct cadence, and why the industry names (honing steel vs. sharpening steel) confuse everyone.
How often to sharpen kitchen knives
Evidence-based cadence by user type (home cook, prep-heavy home cook, restaurant). Signals the blade sends when it's time.
Signs your knife needs sharpening
The paper test, the onion test, and six other diagnostics. Which ones actually correlate with edge geometry and which are folk lore.
How sharp a kitchen knife should be
Edge angle targets by knife style, HRC explained, and the professional-standard benchmarks home cooks rarely hit without a proper sharpener.
Running a local sharpening service
Same-day porch pickup model, pricing economics, how professional sharpening differs from pull-through and electric sharpeners.

On-the-record quotes
Use with attribution to “Michael Kempf, owner of Seriously Fast Sharpening in Austin, TX.” For a customized quote on your specific angle, email or call directly.
“A sharp knife is a safe knife. Every kitchen injury I've ever seen started with somebody pushing harder because the blade wasn't cutting.”
“Honing doesn't remove metal — it just straightens the edge you already have. If your knife is truly dull, no amount of honing will bring it back.”
“Most home cooks don't need exotic Japanese stones or a $400 electric sharpener. They need their knife sharpened properly twice a year and a honing steel they actually use.”
