Sharpening a spearhead for buhurt without breaking IMCF safety rules

For fighters competing under International Medieval Combat Federation rules, the spear is one of the more delicate pieces in the kit. A well-kept blade helps you control the point, place thrusts accurately, and avoid the embarrassing bent tip that ends up wrapped in gaffer tape at the bottom of a tournament bag. At the same time, the federation has clear boundaries on how aggressive an edge can be, because every fight is fought against a real human opponent wearing a real gambeson and helmet.

Across Melbourne, Brisbane, Sydney, and the regional clubs that feed into Australia's Confederation of Australian Medieval Combat affiliates, the question of how sharp is sharp enough comes up constantly. Local regulations, shipping realities, and access to professional sharpening services all shape how fighters approach spearhead maintenance. This guide walks through the steps that keep a spear combat-effective while staying firmly inside the published safety framework, so you can step onto the list field with confidence.

Understanding the IMCF edge requirements

The IMCF rulebook distinguishes between sharpened edges used for cutting techniques and the geometry required of thrusting weapons. For polearms and one-handed spears, the federation is firm about a point that is not sharpened beyond what is necessary to penetrate the legal target area. The rule does not require a butter-knife edge; it requires a tip shaped for clean entry into the strike zone defined in the technical regulations. Fighters who file their spearhead into a razor usually discover that a marshal will reject it at the weigh-in or, worse, after it has already caused an unnecessary wound on the list.

The difference between pointy and sharp matters. A pointy spear can be sharpened on a coarse belt to a defined shoulder, leaving a small flat that pushes fabric aside rather than slicing skin. A spear honed to a keen edge removes material quickly and tends to skate across armour padding. Marshals testing with their thumb pad or a calibrated tester will reject the latter. Most Australian competitors learn this the hard way during their first interclub bout, which is why club smiths in Adelaide and Hobart talk about tour-legal geometry long before they talk about mirror polish.

What this means in practice is that the goal of sharpening is mechanical, not aesthetic. You are shaping a tip that resists bending under repeated strikes, holds up to the occasional clang against a shield rim, and still passes inspection. Keeping a record of the angle, belt grit, and date helps you replicate a legal edge between events, which matters more than the shine.

Choosing steel and equipment suited to local conditions

Spearheads used in IMCF events typically come in 51HRC to 54HRC spring steel, stainless variants, or mild steel for training-only pieces. The harder the steel, the longer the edge holds but the harder it is to reshape in a regional workshop. Many Australian fighters source through international suppliers, but import delays through customs can mean your new head sits in a Melbourne depot for weeks. Buying from local smiths in New South Wales and Victorian maker spaces cuts that delay, though it sometimes means a slightly softer alloy.

Humidity also plays a quiet role. Coastal clubs in Brisbane, Perth, and Sydney deal with salt air that pits steel faster than dry inland centres such as Canberra or Toowoomba. A spearhead left in a damp kit bag will flash-rust by morning. Wiping the metal with a light oil after each sharpening session is not optional maintenance; it is the only way the geometry survives until the next tournament. A thin film of camellia oil, food-grade mineral oil, or wiped-down WD-40 is enough.

Thickness matters as well. Spearheads stamped from 3 mm plate behave very differently from hand-forged 4 mm heads. The thicker the spine, the more aggressive you can be with a file or grinder before risking overheating and losing temper. Newer Australian competitors often choose thinner heads because they are easier to lift and control, then discover the tip bends after a single shield strike. Talking to your club's equipment officer before purchase simplifies every sharpening session that follows.

Setting up a workshop that meets Australian standards

Before any metal touches a belt, your workspace needs to behave like a small machine shop. A solid bench, a vice that grips without crushing the socket, eye protection, hearing protection, and a fire extinguisher within arm's reach are non-negotiable. Australian workplace health and safety rules are enforced strictly even in private garages, and a grinder throwing sparks into a pile of rags is a genuine fire risk. Keep a clear floor, mount the grinder to the bench, and never sharpen in socks and thongs.

For most fighters, a 1 x 30 inch belt grinder with ceramic belts in 80, 120, 220, and 400 grit is plenty. A finer 600 or 1000 grit leather strop satisfies the eye but is not necessary for tournament geometry. Local suppliers such as Abrasive Industrial Supplies in Brisbane or Mitre 10 keep belts in stock, though serious competitors often order direct. Spare belts, a marker pen, calipers, and a small square round out the kit.

It is worth mentioning that any sharpening work produces dust and filings. Keep your PPE on, brush filings into a bin rather than sweeping them into the air, and wash your hands before handling any other kit. The same spearhead that passes inspection can also pass a splinter of rust into a cut on your finger, and a finger infection the week before a nationals trip is a preventable disaster. A clean workshop is as much a part of the safety regime as the rules on the field.

The sharpening process step by step

Mark the centreline of the spearhead with a marker before any grinding. The centreline tells you where the point sits and whether you are drifting to one side. A spearhead that has been hit repeatedly often develops a slightly bent tip, and straightening that bend on the grinder is the first job. Heat the bend gently with a propane torch if needed; never force steel cold, because cold-bending is the fastest path to a crack.

Begin with the 80 or 120 grit belt to establish the angle. Hold the spearhead so the bevel meets the belt at roughly 20 to 25 degrees, draw it across in short passes, and let the grit do the work. Pressing too hard heats the edge, discolours the steel, and softens the temper. Dip the head in water between passes if needed, although constant quenching can crack hardened steel. The aim at this stage is to bring the tip back to a defined point, not to grind the head down to a needle.

Move up through 220 then 400 grit, reducing pressure and increasing the number of light passes. Each grit removes the scratches from the previous one. When the tip looks symmetrical and the marker line has disappeared evenly on both sides, you are at the correct geometry. Strop on a loaded leather wheel if you want a polished look, but remember that mirror edges rarely survive their first shield strike and may push you outside the legal sharpness window. Finish by wiping the head down with an oily rag.

Testing, documenting, and maintaining your edge

Once the head is shaped, test it on scrap leather or folded heavy canvas. The spear should penetrate the canvas with firm pressure, not slice through it. If it cuts cleanly like a razor, the edge is too keen and should be dulled back with a single pass on the 220 grit belt. Many Australian clubs run a pre-bout marshal check; an edge that digs into a gloved thumb fails. Knowing that feel tells you whether to work the edge back or leave it as is.

Keep a small logbook or phone note for each spearhead: date, grit used, angle, and any issues you noticed. Spearheads accumulate damage over a season, and tracking the work lets you see when a head is approaching the end of its safe life. Cracks, deep nicks, and tips that drift back toward the centreline after every sharpening are signs the head should be replaced rather than reshaped. Most competitive fighters in Australia replace their spearhead every two seasons, though casual fighters can stretch that out.

Field-side maintenance matters too. After a bout, wipe the head clean, check the socket for cracks, and store the spear vertically. Spears left flat under a kit bag develop flat spots on the tip from their own weight, and a flat-tipped spear is harder to bring back to legal geometry. A simple spear rack in the corner of your garage keeps the tip supported. Many Australian competitors build theirs from Bunnings offcuts, treated pine, and a couple of rubber grommets to cushion the shaft. The cost is small, the benefit is real.

Working with Australian armourers and clubs

Most cities with an active medieval combat scene host at least one or two smiths who understand the IMCF ruleset and can sharpen or reshape a spearhead to tournament standard. In Melbourne, the Brunswick and Campbellfield maker spaces list smiths familiar with buhurt kit, while Brisbane's Yatala industrial area has at least one specialist grinder who advertises within the local HEMA community. Costs typically sit between forty and eighty Australian dollars for a full reshape and edge, which is reasonable insurance if your grinding skills are still developing.

Joining your national association and attending sanctioned events gives you access to club workshops, training days, and shared grinders already calibrated for legal geometry. New fighters should ask senior members to supervise their first sharpening session; the lessons learned on someone else's mistakes save you from ruining a brand new spearhead. Several Australian clubs run annual maintenance weekends, often in the cooler months, where members share belts, files, and advice. These weekends double as informal inspections, so your kit ends up checked before it ever sees a marshal.

If you wear a helmet that sits a little snug or rides high, check the best head protection options for fighters with larger heads before buying a second spearhead, because a comfortable fit on your skull affects every thrust you throw. For those still working out the right gambeson weight for their class, this gambeson thickness guide pairs nicely with the spear work covered above. The two pieces of kit work together on the list, and a balanced setup is what keeps you sharp, legal, and competitive.

Visit the IMCF website, contact your national affiliate, and book a session with a qualified armourer before your next tournament. Bring your spearhead, your logbook, and a list of questions, then put in the practice that turns a piece of shaped steel into a reliable extension of your fighting style. The list field rewards preparation, and a spear that is sharp, legal, and well-maintained is one of the simplest advantages you can give yourself before the whistle blows.
