🔍 Introduction: A Clean Knife Is a Reliable Knife
Whether you’re field dressing, slicing cordage, or prepping dinner, your knife’s performance depends on how well you maintain it. Cleaning and oiling might seem basic, but they’re essential rituals that extend your blade’s life and protect its edge.
This guide walks you through how I—and many seasoned users—keep our knives in working condition no matter what they’re used for.
🧼 Section 1: Cleaning Your Knife — Step by Step
🧽 What You’ll Need:
Warm water
Mild dish soap
Soft-bristled toothbrush or nylon brush
Microfiber cloth or lint-free towel
🧼 Cleaning Process:
Disassemble if possible (folder owners, this one’s for you).
Mix soap and warm water. Use the brush to clean the blade, handles, pivot points, and grooves.
Rinse thoroughly.
Dry immediately to avoid rust—especially with carbon steel blades.

🛢️ Section 2: Oiling Your Knife — The Right Way
🛠️ Choose the Right Oil:
Food-grade mineral oil – Best for kitchen or EDC knives
Tactical lubricants – Excellent for folders and high-use field knives
❌ Avoid cooking oils – They go rancid and attract gunk
💧 How to Apply:
Use a drop or two of oil on a clean cloth
Lightly coat the blade and steel hardware
Apply a small drop to pivots (for folding knives), then open/close a few times
Wipe away any excess

🧼 Clean & oil monthly (or after any heavy use)
🌧️ Wipe dry immediately after exposure to rain or sweat
🧠 Inspect screws, clips, and liners every few weeks
🧊 Store in a cool, dry place—avoid leaving it in humid sheds or gloveboxes

No fancy gear needed—just five minutes, a little oil, and some respect for your blade.
