Viking Axe Care: How to Maintain a Carbon Steel Axe
Carbon steel Viking axes stay rust-free with one simple habit: keep the head dry and wipe a thin film of oil onto the steel before you put it away. Add an occasional handle oiling and sensible storage, and a hand-forged axe will outlast its owner. Here is the full routine, step by step.
Why carbon steel needs care at all
Functional Viking axes are forged from high-carbon steel (ours are typically AISI 1065, hardened to roughly 48–54 HRC) because it takes and holds a real edge. The trade-off is that carbon steel oxidises: leave it damp and unprotected and orange-red rust will bloom within days. A dull grey patina, on the other hand, is harmless — it is a stable oxide layer that many owners deliberately keep because it looks the part and even slows further corrosion. Rule of thumb: grey is fine, orange is not. The same forge-and-steel logic applied a thousand years ago, which is why the axes in our illustrated guide to Viking axe types survive mostly as excavated heads — iron that was not cared for.
The 60-second routine after every use
- Wipe the head dry with a clean cloth — fingerprints alone hold enough moisture and salt to start rust spots.
- Apply a thin oil film. Light mineral oil, 3-in-1 oil or camellia oil all work; you need a sheen, not a dripping coat.
- Store it dry. Indoor air, not a damp garage or shed. If the axe lives on a wall or rack, it needs the oil film refreshed every month or two; in a case, add a silica gel pouch.
Removing rust when it appears
Caught early, rust is a five-minute fix: rub the spot with fine steel wool (0000 grade) and a few drops of oil until the orange lifts, wipe clean, and re-oil. For heavier patches, work up from the finest abrasive that does the job rather than attacking the steel with coarse sandpaper — aggressive grinding removes the forge finish and any etched detail. Never leave rust "for later": it pits the surface, and pits are permanent.
Edge care: sharpen the working axes, leave the display pieces
A functional axe is sharpened like any other: a few passes with a fine file or coarse whetstone to set the bevel (axes like a fairly robust edge, around 25–30 degrees inclusive), then a finer stone to refine it. Between sharpenings, stropping on leather keeps the edge keen. Two honest cautions: display and collector's pieces that ship unsharpened should stay unsharpened — they are built around their carving and finish, not around edge geometry — and each of our product pages states clearly whether an axe is functional or display, as on the fully functional Skeggøx bearded axe.
How to sharpen an axe, step by step
You do not need machines — a file, a stone and ten minutes will bring back a working edge, and the routine is the same whether you are sharpening a small hatchet or a full-size axe.
- Secure the axe. Clamp the haft or brace the head firmly on the bench with the edge facing away from you. Thick gloves are cheap insurance.
- Set the edge with a file. Push a fine mill file along the bevel from heel to toe, following the existing angle — roughly 25–30 degrees inclusive. Work both sides evenly until nicks are gone and you can feel a faint burr on the opposite side of the edge.
- Refine with a stone or puck. Use an axe sharpening stone — the classic choice is a round sharpening puck, a palm-sized two-grit disc made exactly for axe bevels — in small circular motions along the edge, coarse grit first, fine grit to finish. A little water or oil on the stone floats the metal dust away.
- Strop. A few trailing passes on leather (an old belt works) strip the burr and polish the edge keen.
- Wipe and oil. Sharpening leaves bare, unprotected steel — finish with the same thin oil film as always.
A word on grinders and powered sharpeners: a bench grinder can sharpen an axe in seconds — and ruin it almost as fast. High-speed grinding overheats the thin edge, and once the steel discolours blue or straw, the temper (the hardness the smith put in) is gone for good. If you must use one, keep the speed low, the touch light, and dip the head in water constantly. For a hand-forged axe, the file-stone-strop routine is slower, safer, and all it ever needs.
Handle and leather care
Wooden hafts — ash, beech, oak or rosewood — dry out over years. When the wood starts to look pale or feel rough, rub in a little boiled linseed oil and buff it off; once or twice a year is plenty in normal indoor conditions. Check now and then that the head still sits tight on the haft. Leather wraps and blade covers want a leather conditioner occasionally — but here is the counter-intuitive rule: do not store the axe inside its leather cover long-term. Leather absorbs and holds moisture against the steel, which is exactly how a "protected" blade rusts. The cover is for transport; storage is dry air and an oil film.
Quick reference
- After handling: wipe dry, thin oil film.
- Monthly (displayed axes): refresh the oil film.
- At first rust spot: 0000 steel wool + oil, then re-oil.
- When the edge dulls: file → stone or puck → strop, then oil.
- Once or twice a year: linseed oil the haft, condition the leather, check the head seat.
- Always: store out of the leather cover, out of damp.

Frequently asked questions
What oil should I use on a carbon steel axe head?
Any light, non-drying oil works: mineral oil, 3-in-1 or camellia oil. The goal is a thin protective film that blocks moisture. Wipe it on, buff off the excess, and refresh it every month or two on displayed axes.
How often should I oil a Viking axe?
Wipe and oil the head after every handling session, and refresh the film every one to two months on an axe that hangs on display. In humid climates or unheated rooms, check it more often.
How do I remove rust from an axe head?
Rub the spot with 0000-grade fine steel wool and a few drops of oil until the orange rust lifts, wipe clean and re-oil. Deal with rust as soon as you see it — left alone it pits the steel permanently.
What is the best way to sharpen an axe?
By hand, in three stages: set the bevel with a fine mill file at roughly 25–30 degrees inclusive, refine it with a sharpening stone or round axe puck in circular motions, then strop on leather to remove the burr. Finish with a thin film of oil on the bare steel.
What is an axe sharpening puck?
A palm-sized, round sharpening stone made for axe bevels, usually with a coarse grit on one side and a fine grit on the other. Its shape lets you work the stone in small circles along the curved edge — the easiest way to sharpen an axe at home or in the field.
Can I sharpen an axe with a grinder?
It is risky. A high-speed grinder overheats the thin edge in seconds, and once the steel discolours the temper is permanently ruined. If you use one at all, keep the speed low and dip the head in water constantly — but a file, stone and strop are the safer choice for a hand-forged axe.
Should I store my axe in its leather cover?
No. Leather holds moisture against the steel and will cause rust in long-term storage. Use the cover for transport, then store the axe in dry indoor air with a light oil film on the head.
Should I sharpen a display Viking axe?
No. Display and collector's pieces that ship unsharpened are built around their carving and finish, not edge geometry, and sharpening can damage the detail. Only maintain the edge on axes sold as functional — the product page states which is which.
