Blade Size Finder
Most people buy longer than they end up enjoying. This tool asks what you are buying, what you will do with it, and — for swords only — how tall you are. It returns a length range, a grip or handle length, the reasoning behind the number, and a physical check you can do at home before you spend anything. The ranges are general blade-sizing standards, not our catalogue. If the right answer for you is something we do not make, the tool says so.
1. What are you sizing?
2. What will you use it for?
3. How tall are you?
Height changes the answer for swords and for almost nothing else. A sword has to clear the ground on the draw and its arc is set by your arm plus the blade.
How the Tool Decides
There is no formula that turns a person into a blade length, and anyone who gives you one is selling something. What the tool does instead is work through the same constraints a maker would ask you about, in the order that rules the most lengths out fastest.
The task comes first. Length buys reach and momentum, and costs you control. That trade is the single biggest factor in every category except swords, which is why the second question is always about use rather than about you.
Height only enters for swords. A sword has to clear the ground when held at your side, and the arc of a cut is governed by your arm length plus the steel. Someone of 160 cm with a 36-inch blade has a geometry problem, not a taste problem. For a kukri, machete, knife, spear or axe, height is close to irrelevant — the vegetation does not care how tall you are. What changes with the person is grip length, and hands vary far more usefully than heights do.
The ranges are general, not ours. A traditional service kukri is around 11 inches whoever forges it. A one-handed arming sword blade sits around 28 to 32 inches in the historical record. Those numbers are not our house style, and the tool gives them straight. Where the answer falls outside what we forge, it tells you rather than nudging you toward the nearest thing we happen to sell.
What the Tool Will Not Do
It will not tell you what is legal where you live. Blade-length rules vary by country, state and territory, usually govern carrying rather than owning, and some jurisdictions restrict import of particular types regardless of length. Check your own local law before you order.
It will not replace holding one. If you are genuinely unsure, a shop that lets you handle three sizes gives you something no online tool can. We hold no stock, so we cannot give you that either — which is why every result ends with a physical check you can run with a broom handle and a tape measure.
It will not push you upward. The default bias of this tool is shorter. Almost nobody finds a controllable blade disappointing after a season of use, and plenty of people find an ambitious one stays in the cupboard.
Everest Forge — Forged to Order
Any Length, Because Nothing Is Pre-Made
We hold no stock. Every blade is forged after the order is placed, so the length the tool gives you is something we can actually build rather than something you have to find. Configure a pattern yourself, or send dimensions and we will quote it.

Frequently Asked Questions
How do I know what size blade to buy?
Work through four constraints in order: what you will actually do with it week to week, how much room you have to swing it, where it will live when you are not using it, and what your local law and courier allow. Whatever length survives all four is your size. The tool above walks the first two and gives you a range; the full reasoning is in our blade size guide.
Does my height matter when choosing a blade?
Only for swords. A sword has to clear the ground when held at your side and its cutting arc depends on your arm plus the blade, so height genuinely changes the answer. For kukris, machetes, knives, spears and axes, height is close to irrelevant — those are sized by the task. What does change with the person in every category is grip length.
What is the most useful blade length for general use?
Between 10 and 15 inches for a single do-everything blade. That covers a traditional service-size kukri, a compact machete and a large bushcraft knife. Shorter than 8 inches and you lose chopping power entirely. Longer than 15 inches and you are carrying a dedicated tool rather than a general one.
Is a longer blade better?
Rarely. Length buys reach and momentum and costs you control, and weight climbs faster than length because a longer blade needs a thicker spine or a more aggressive taper to stay rigid. The bigger cost is where the mass sits — weight far from your hand takes longer to stop and redirect, which is what actually tires people out.
Can I order a blade in a length you do not stock?
We hold no stock at all, so length is a build decision rather than a stock lookup. Many patterns carry a length option, the configurator prices your chosen length live, and anything outside those ranges is quoted as a custom piece. If the tool gives you a size we do not normally make, that is what custom forge is for.
Are these sizes specific to Everest Forge blades?
No. The ranges are general blade-sizing standards drawn from how each blade type has historically been made and used — a traditional service kukri is around 11 inches whoever forges it. The tool gives you the honest range first and points you at our catalogue second.
