A sharp knife is safer than a dull one

A dull knife slips. This is the first thing they teach in any kitchen worth working in. A sharp blade goes where it's pointed. A dull blade goes where the pressure sends it, which is wherever the surface offers least resistance - on a tomato, that's sideways and down toward the hand.

The physics are simple. A sharp edge needs almost no force. Set the blade, draw it through, and the cut happens at the contact point. A dull edge requires pushing, and pushing loads the handle with energy that has to go somewhere when the resistance breaks.

Professionals sharpen constantly. Not once a week. Every shift, sometimes twice. A line cook working prep runs a honing steel across the blade every 20 minutes or so. The motion takes three seconds. Three passes per side. It isn't maintenance the way most people mean the word. It's the cost of keeping the tool exactly where it's told to go.

The sharpening itself is worth following. A whetstone sits on a damp towel to keep it from sliding. The knife goes across at 15 degrees - 20 for a German blade - in a smooth arc, heel to tip. The sound changes when the angle is right. Scrape becomes hiss. Thirty passes per side, then a finer stone, then repeat. A full sharpening takes ten minutes. Most cooks do it weekly.

Software that gets patched daily is more stable than software that ships a large update every quarter. The quarterly release is the dull knife. Months of accumulated changes applied at once. When something breaks, the failure surface is wide and nobody can tell which change caused it. The daily patch is the honing steel. Small correction. Edge stays true.

A person with unclear authority works the same way. Not because they're unskilled - because every action requires extra force. They push harder to get decisions through. They route around ambiguity with workarounds. When something goes wrong, nobody can trace it. The force was spread across too many surfaces.

Give the same person clear authority and sharp tools. The cut goes where they aim it. If the aim is wrong, the damage is visible and traceable. That kind of failure gets fixed. The distributed kind - the one that belongs to everyone and therefore no one - never gets found, so it never gets repaired.

The instinct after a visible mistake is almost always to dull the tool. Add a review. Require a second signature. Route the decision through a committee. Each layer feels like safety. What it does is add force. More people loading energy into the same handle. When the blade slips - and it will - the failure belongs to no one because everyone was holding the knife.

A kitchen that runs this way shuts down inside a week. The rule in any working kitchen is not complicated. Keep the edge sharp. Respect what sharpness can do.

Most cuts happen on dull blades held by hands pressing harder than they should.
